Garfield County, Colorado - Potential Impacts on Ground-Water Due to the Use of Individual Septic Systems Dear Ms. Caloia: As requested, Mclaughlin Water Engineers, Ltd. (MWE) conducted an evaluation of the potential effects on ground-water quality due to the use of individual septic systems at the Los Amigos Ranch residential development in Garfield County, Colorado. A copy of our report is enclosed. The proposed subdivision includes five separate filings of the approved Los Amigos PUD. Filings 6-10 consist of 168 single-family lots on atotal of 1,703.058 acres of land, of which 975.927 acres is dedicated for open space land use. There are four residential lots totaling 223.6 acres (averaging about 55.9 acres/lot). The remaining 164 single-family lots cover an area of about 503.5 acres with an average lot size of about 3.1 acres each. Each lot is to be equipped with an individual (nonevaporative) septic system. Upon reviewing the pertinent development plans, soil test data, geologic maps, and published well records and reports, we have concluded the density and number of individual septic systems and the local hydrogeologic conditions are not favorable for the use of individual septic systems. Ground-water contamination due to nitrate loading will likely occur if individual septic systems are used in the planned residential development. In localized areas, the nitrate concentration as nitrogen of shallow ground water may significantly exceed l0 mg/I, the primary drinking water standard. Therefore. the use of individual septic systems in the planned development is not recommended and should not be approved by Garfield County Officials. If you have any questions, please feel free to call me at (303) 458-5550. Respectfu lly submitted, Mclaughlin Water Engineers, Ltd.eer.#fut U1?,hff:'#:l;*1,1 'c P G Mclaughlin Water Engineers, Ltd. Denver, Colorado 80211 (303) 458-5550 jr*laAmigs2.wpd I I I T t T I I T t t I T T T I t T I I T T T I T T I t I I I T I I T I T T INTRODUCTION At the request of Veranda Ventures, Inc. and Colorado Mountain College, Mclaughlin Water Engineers, Ltd. has evaluated the potential effects of proposed individual nonevaporative septic systems at the Los Amigos Ranch development on ground-water quality. The Los Amigos Ranch P.U.D. is a planned residential subdivision located in Garfield County, Colorado about five miles southeast of Glenwood Springs' The residential development is to include 168 single-family lots on a total of about 1,703 acres of land, of which nearly 976 acres are dedicated for open space land use. There are four residential lots totaling 223.6 acres. The remaining 164 single-family lots cover an area of about 503.5 acres lvith an average lot size of about 3.1 acres each. Each lot is to be equipped with an individual (nonevaporative) septic system. The disposal of domestic wastewater is accomplished in many areas though the use of septic tanks and soil leach fields. Anaerobic decomposition of wastes takes place in the septic tank. The liquid waste is carried to a soil leach field, where it seeps through the vadose (unsaturated) zone to the water table. A major contaminant of ground water from individual septic systems is nitrate which is a conservative (stable) ion. The most important factorthat influences the development ofground-water contamination from septic tanks is the density of septic systems in an area. Documented cases of widespread ground-water contamination from septic-tank systems have been in areas where the lot sizes range from less than one quarter of an acre to three acres (C. W. Fetter, 1994). Septic tanks are most likely to contribute to ground-water contamination in areas where: there is a high density of homes with septic tanks, the soil layer over permeable bedrock is thin, the soil is very permeable, or the water table is close to the land surface. Areas with high population densities should not be served with septic tanks, and areas with thin soils, very permeable soils, and high water tables should be avoided (C W. Fetter, 1994). To evaluate the potential effects of proposed individual nonevaporative septic systems at the Los Amigos Ranch development on ground-water quality, information about the development was reviewed, including pertinent development plans, soil-test data, and geologic reports. In addition, State Engineer's Office well records were reviewed and evaluated, and recent geologic reports were obtained from the Colorado Geological Survey and the U. S. Geological Survey. Published documents concerning septic-tank design, operation, and T T T T T T I T T t T T T T T T t T T effluent quality were also reviewed. presented below are discussions of the hydrogeology of the plamed development area and potential impacts on ground-water flow and quality. These discussions are followed by conclusions and recommendations. HYDROGEOLOGY The occurrence and movement of ground water in the regional area between Glenwood Springs and Carbondale, Colorado (specifically east of the Roaring Fork River, north of Cattle Creek, South of Red Canyon, and bordered on the east by Spring Valley) are determined by major stratigraphic and tectonic factors. Shallow ground-water flow above the Roaring Fork river valley is largely controlled by significant fracture (or secondary) permeability as opposed to intergranular (or primary) permeability in otherwise tight rock formations. Presented in the paragraphs below are descriptions of the major hydrostratigraphic uruts that are exposed in the regional area described above . This discussion is followed by a description and interpretation of unusual structural features that affect the movement of ground water and is based on extensive lvork by the Colorado Geological Survey. Mai or Hvdrostratisranhic Units The major geologic units that affect the occurrence and movement of ground water in the regional area include Pennsylvanian, Permian, Tertiary, and Quaternary agedeposits. They are described below in ascending order and are shown in Figure l. [Fee] Eagle Valley Evaporite (Middle Pennsylvanian). This is a thick sequence of evaporite rocks consisting ofmassive to laminatedglpsum, anhydrite, halite (salt), and beds of light-colored mudstone and fine-grained sandstone, thin limestone and dolomite beds, black shale, and possibly eolian deposits. Beds commonly are intensely folded, faulted, and ductilely deformed by diapirism (vertical movement from below), flolvage, dissolution-related subsidence or collapse, load metamorphism, hydration of anhydrite, and Laramide tectonism (mountain building). The formation is generally poorly exposed north of Cattle Creek and south of Spring Creek. Occurrencc of prominent gypsum outcrops on hillsides may be evidence of recent or on-going diapiric activity. Contact with the overlying Eagle Valley Formation is both conformable and intertonguing and is defined as the base of the lowest red bed within the Eagle Valley Formation. The Eagle Valley Evaporite was deposited in a marine evaporitic basin known as the Eagle Basin. The base of the formatiou is not exposed in the regional area. The formation thickness may range from about 1,200 to as much as 9,000 feet where it is tectonically thickened along the axis of the Cattle T I T I t t I I I I T T I I t I T T t Creek Anticline. The Cattle Creek Anticline trends north to south along the Roaring Fork River. Based on oil well drilling near the mouth of Cattle Creek, the formation contains about 2,065 feet of g)?sum, anhydrite, and siltstone, and at least 935 feet of halite. Drilling of the oil well stopped in the halite deposit. The Eagle Valley Evaporite contains cavernous voids as much as several feet in diameter and tens of feet deep that resulted from near-surface dissolution of halite and gypsum. It is prone to development of sink holes into which overlying deposits may subside or be piped. Evidence of sinkhole formation is shown in Figure I near Colorado Mountain College and near Spring Valley' [Pel Eagle Valley Formation (Middle Pennsylvanian). This formation is comprised of interbedded reddish-brown , Etty,reddish-gray, and tan siltstone, shale , sandstone, g,?sum, and carbonate rocks. The unit represents a stratigraphic interval in which the red beds of the overlying Maroon Formation grade into and intertongue with the predominantly evaporitic rocks of the Eagle Valley Evaporite. It includes rock types of both formations. The thickness is variable, ranging from about 500 to as much as 3,000 feet on the west side of the Cattle Creek Anticline. The Eagle Valley Formation is conformable and intertongues with the overlying Maroon Formation and underlying Eagle Valley Evaporite. Contact with the Maroon Formation is placed at the top of the uppermost evaporite bed or light-colored clastic bed below the predominantly red-bed sequence of the Maroon Formation. It was deposited in the Central Colorado Trough on the margin of an evaporite basin in fluvial, eolian, and marine environments. The formation may be susceptible to subsidence and sinkholes. Surficial deposits derived from it are prone to collapse, compaction, piping, and corrosion. The formation is generally exposed north of Cattle Creek and south of Spring Valley. [PFm] Maroon Formation (Lower Permian? And Upper Pennsylvanian). This formation is comprised of reddish-brown beds of sandstone, conglomerate, siltstone, mudstone, and shale and minor, thin beds of gray limestone. The top of the formation is not exposed in the regional area. The conglomerate contains pebble-and cobble-sized clasts of quartz, feldspar, and granitic rock fragments. It is commonly arkosic and micaceous. The entire formation is ranges in thickness from 3,000 to 5,000 feet. The exposed thickness in the regional area is only about 800 feet. Clastic rocks in the lower part of the Maroon Formation were deposited in basin-margin, alluvial fan and fan-delta environments in the Central Colorado Trough, whereas the limestones were deposited in shallow marine environments. The upper part of the formation was deposited in the Central Colorado Trough in fluvial and eolian environments. The formation is prone to rockfall rvhere exposed T t T T T I t I t I T T I T I T t T I in steep cliffs east ofthe Roaring Fork River. Beds are normally well cemented and jointed giving the formation a blocky appearance. Some hydraulic connection with the overlying basalt formation is probable because ofjoints and fractures. [Tb] Basalt (Miocene). Multiple and extensive flows of (lava) basalt, basaltic andesite, and basaltic trachyandesite underlie the entire Los Amigos Ranch property and much of Spring Valley. Basalt is a fine-grained, sometimes glassy, basic igneous rock. In places, the unit includes slightly indurated (cemented) sediments. Most flows are olivine basalt; many are porphyritic (large crystals in a fine- grained groundmass). The groundmass is predominantly plagioclase and pyroxine, with lesser amounts of olivine, glass, pigeonite, augite, and magnetite. This mineralogy renders the basalt very hard and diffrcult to excavate. Individual basalt flows are commonly 5 to 25 feet thick. The maximum thickness of the basalt deposit is about 300 feet. Due to the absence of deep borehole data in the Los Amigos Ranch property area, the thickness of the basalt deposit beneath the property is not precisely known. The thickness has been estimated to be as much as 160 to 200 feet by Hepworth-Pawlak Geotechnical, Inc. of Glenwood Springs, Colorado (1997). The basalt flows unconformably overlie westerly dipping Permian and Pennsylvanian rocks. The basalt deposit exhibits extensive polygonal sets of fractures (columnar joints) formed at right angles to the surfaces of flows, especially in the finer-grained portions ofthe lava flows. These joints are largely interconnected and are highly permeable conduits for the flow of ground water. Several high-capacity wells have been constructed locally in the basalt for municipal water supply purposes. Steep cliffs of basalt are a source of rock-fall debris due to weathering and failure along the joint planes. Based on a review of available records of local wells completed in basalt, the hydraulic conductivity of the igneous deposit probably ranges from less than 50 to more than 100 ftlday. Reported yields from local wells have been as high as 400 gpm. However, the overall specific yield of the basalt formation is probably low compared to an alluvial aquifer because yield is provided by interconnectedjoints and fractures as opposed to intergranular porosity. In the regional area, Miocene? sedimentary deposits [Ts] of alluvium and colluvium are sandwiched between early lava-flow events. These deposits are comprised of clast-supported, fluvial, silty, sandy pebble and cobble gravel with local silty and sandy deposits. The unit is poorly exposed in the regional area. Most clasts are well rounded to moderately well rounded and moderately to highly weathered. Thickness ranges from about 40 feet to a few hundred feet. This material is a distinct geologic unit but is considered to be a part of the greater basalt hydrostratigraphic unit. 2. 3. 4. 6. 7. I T T t t I I I T I I I t T I I T I I tQt & Ql,l Lacustrine Deposits (Holocene and Pleistocene). Stratified and nonindurated lacustrine (lake) deposits comprised of medium- to dark-gray, organic-rich, silty clay and silt, yellow-brown clayey silt, and medium-reddish, well-sorted, fine to coarse sand underlie the central floor of Spring Valley (Qlr). ft also crops out along the margins of the valley in bluffs that are 20 to 40 feet higher than the central valley floor (Ql,). Exposed thickness of the deposits range up to 40 feet. Based on well construction data, the lacustrine deposits are more than 100 feet thick in the vicinity of Colorado Mountain College. Typically, the lacustrine deposits yield moderate amounts of water to wells' In Spring Valley, the lacustrine deposits are underlain directly by basalt flows and some lesser amounts of fractured and jointed Maroon Formation. Based on a review of available records of local wells completed in this sediment, the hydraulic conductivity of the lacustrine deposits probably ranges from less than 1 to less than l0 fl/day. Structural Features The regional area encompassing the Los Amigos Ranch property is on a shallor,v structural bench that lies between several folds, faults, and uplifts. The structuralbench has undergone significant deformation during the Neogene (Miocene and Pliocene periods of the Tertiary). Unusual structural features of this deformation that affect the occurrence and movement of ground water include: 1.linear and arcuate synclinal sags, some with faulted limbs; intrusive contacts between sedimentary formations; sets of orthogonal faults; circular, elliptical, rectangular, and irregularly-shaped bowlJike structural troughs ofvarying sizes; 5. a large, arcuate, half graben whose floor rvas occupied by a lake until drained by homesteaders (i.e.; Spring Valley); valley anticlines; and complexly deformed, highly broken and brecciated blocks of randomly oriented bedrock (Pleistocene and/or late Tertiary collapse debris). These distinctive structural features are pervasive wherever evaporitic rocks lie at or near the land surface. Many of the structural sags, troughs, and bowls contain locally-derived sediments eroded from adjacent I T T I I t I I I I I T I I I I I I I uplands. Many ofthese sediments are deformed but less so than the underlying bedrock. This deformation is believed to be restricted to the Eagle Valley Evaporite and overlying deposits. Bedrock older than the Eagle Valley Evaporite has not been affected by the salt tectonism and dissolution. Geomorphically, these unusual structures have combined to create a landscape that has the classic characteristics of karst topography. Open voids and caverns can be seen in many outcrops ofthe Eagle Valley Evaporite, and sinkholes, some quite large, have developed in bedrock formations overlying the evaporitic rocks. Quaternary deposits may be affected by this unusual type of deformation. River terraces are upwarped away from modern river channels. Large broad, closed or nearly closed depressions and swales (subsidence troughs) have developed in many outwash terraces. Sinkholes are locally abundant in surficial deposits. Drainage pattems and the extent of many of the basin-filling surficial deposits are influenced by the sinkholes and subsidence troughs, folded river terraces, folded and faulted bedrock, and collapse debris. The regional area is part of a larger topographic depression the coincides in part with the area where evaporitic rocks lie at or near the ground surface. The depression is believed to be a large collapse block that has resulted from dissolution and flowage of evaporitic rocks from beneath the area. Neogene igneous rocks are well preserved within the down-dropped collapse block. Both the lateral extent and amount of vertical collapse is defined by structural deformation within the Neogene igneous rocks. The synclinal sags, intrusive contacts between sedimentary formations, orthogonal fault sets, bowl-like structuraltroughs, arcuate halfgraben, valley anticlines, collapse debris, and folded Pleistocene outwash terraces occur within the collapse block. Neogene deformation ofthe regional area involves ( 1) regional down-to-the-east tilting of Miocene basalt flows that unconformably overlie moderately west-dipping sedimentary formations and (2) a series of subparallel bedding plane faults that closely follow the bedding ofthe moderately west-dipping sedimentary beds and offset overlying Neogene deposits. The bedding-plane faults are downthrown to the west, but blocks of basalt between the faults dip as much as 3 0 degrees eastward, opposite that the underlying pre-Laramide sedimentary formations. This type of deformation can be explained by dissolution of evaporitic rocks that underlie the area or by flowage ofthe evaporites toward the Roaring Fork Valley. As the evaporites were removed, the regional area tilted eastward. Sl,nclinal sags, the bowl-like structural troughs in bedrock, the half graben of Spring Valley, and the presence of collapse debris all can be explained by locally intense subsidence within the regional collapse block. Features such as valley anticlines and intrusive sedimentary contacts are probably a result ofdiapirism. Folded outwash terraces are a product ofeither dissolution-induced, localized subsidence and/or diapiric processes. Ground-Water Flow Conditions A general water-table map of the saturated basalVlacustrine sequence in the vicinity ofthe Los Amigos Ranch I I t I I I I I T I T t I I T I I T t property was developed and is shown in Figure 1. The map was developed from static rvater-level measurements in existing wells, elevations of perennial stream reaches in Spring Valley, topographic maps of the regional area, and the geologic map (Figure l). The wells used to construct the map are listed in Table l.

In other words, the land to be occupied by the Los Amigos Ranch property is a natural recharge zone. Ground water moves away from the mound in all directions with a natural hydraulic gradient that likely ranges from approximately 0.0I to 0.09 feeVfeet. The most gentle gradients are located on the west, north, and east sides of the mound. The steepest gradients occur on the south side of the mound coincident with steep ground slopes. The variable gradients indicate transmissivities of the basalt formation vary directionally and are structurally controlled. Perennial surface florvs in Spring Valley (i.e.; Spring Creek) are maintained by ground-water discharge into the lacustrine sediments from the northeast and east and from west and southwest. A ground-water divide in Spring Valley occurs near the southeast corner of Section 32, T6S,R88W. North of the divide ground water flows northward in the valley to Spring Creek. South of the divide ground water flows toward the municipal well field near Colorado Mountain College and to Cattle Creek. The well field is also supplied by southeasterly ground-water movement from the upland area where the proposed Los Amigos Ranch development is to be located. I I I T T T I I I I I I I I t I I t t POTENTIAL IMPACTS ON GROUND WATER presented in Figure 2 is the Los Amigos Ranch Development P.U.D. along with the general water-table map shown in Figure l. The Los Amigos Ranch development will change the local ground-water conditions. The municipal wells located near the college will be used to supply water to the development for domestic purposes. Landscape irrigation activity and onsite use of individual nonevaporative septic systems rvill increase the local ground water recharge. As a result, ground-water levels will rise. Springs may emerge in the otherwise ephemeral drainages that flow southwesterly through the development. The apex of the ground-water mound will likely shift to the northeast in the direction of greater transmissivities. As the municipal wells pump greater amounts of ground water to supply the domestic needs of the development, greater drawdown at the well field will occur. The increased drawdown at the well field and northeasterly shift of the ground-water mound will combine to increase the overall contribution of ground-water flow from Los Amigos Ranch development area to the municipal well field. The amount of ground-water recharge that will occur from seasonal landscape irrigation will be a function of vegetation types, irrigated areas, and watering practices. The steady-state recharge contribution from the proposed onsite nonevaporative septic systems will be approximately 30 acre-feet per year. This volume was computedassuminganaveragedailydomesticwastestreamof45gallonsperperson(EPA, 1980),3.5persons per single-family residence as per the decreed augmentation plan for the development, and 168 units as per the Los Amigos Ranch P.U.D. At each single-family residence, this recharge rvill occur over a very small area or along a short buried trench through shallow natural or imported surface soils. After the effluent passes through the shallow surface soils, it will percolate rapidly into the interconnected fractures and joints of the basalt formation. Movement through the basalt will be rapid as compared rvith even coarse alluvial sediments such as gravel. Nitrate concentrations in retum flows from landscape irrigation rvill be a function of vegetation types, irrigated areas, and individual fertilization and irrigation practices. There are no septic tank design requirements specifically established to enhance high levels of nitrogen removal in domestic wastewater. Designs that provide excellent solid-liquid separation ensure lower concentrations of nitrogen associated with suspended solids. Organic nitrogen in domestic wastervater readily undergoes decomposition to ammonia in septic tanks. According to the EPA (1980), about 2 to l0 percent of the total nitrogen from the home may be removed in the septic tank. Approximately 65 to 75 percent of the total nitrogen in septic tank effluents is in the ammonia-nitrogen form, indicating a significant level ofdecomposition of organic nitrogen. Nitrification of septic tank effluents occurs readily within sand filters. During nitrification, nearly all the ammonia is converted to nitrate. T T T t T t The total nitrogen concentration of the septic-tank effluent will likely average about 45 mg/l (EPA, 1980) Because of shallorv soils and the hydraulic properties of the basalt formation, only negligible attenuation of organic and ammonia species of nitrogen may be possible. As the effluent from the individual septic leach fields flows through the joints and fractures of the basalt formation, only minimal lateral dispersion will occur. Instead, flows will take onthe appearance of narrow channels of high-nitrate ground rvater inter-fingered with narrow channels of lower-nitrate ground water. As stated above, some of the effluent from the proposed development will flow back to the municipal well field. The presence of volcanic-ash interbeds and basalt fractures partially filled with Quaternary sediments and other debris may inhibit the vertical dispersion of the effluent. As a result, high-nitrate water from the septic leach fields may concentrate near the water table' I coNCLUsroNs AND RECoMMENDATIoNS I I I I I t T T I t t t The proposed density and number of individual nonevaporative septic systems at the Los Amigos Ranch property are high (164 on 3.I-acre lots) and are not favorable to prevent ground-water contamination. In many areas of the proposed development, surface soils are thin or nonexistent. Only fractured and jointed basalt is exposed at the ground surface. Such conditions are not favorable to overall septic system operation. Surface soils are underlain by highly permeable basalt deposits which provide little, if any, dispersion ofthe septic effluent. Septic effluent concentrations ofnitrate as nitrogen are expected to average about 45 mg/I. The proposed use of individual nonevaporative septic systems at the Los Amigos Ranch property will significantly increase the nitrate content of the ground-water supply. In localized areas, the nitrate concentration as nitrogen of shallow ground water may significantly exceed l0 mg/I, the primary drinking water standard. Use of individual nonevaporative septic systems at the Los Amigos Ranch residential development is not recommended as proposed and should not be approved by Garfield County offrcials.

This report presents a response to comments by Resource Engineering, Inc. and a discussion of the fate and transport of'septic effluent. Based upon a review and analysis of additional well data in the project area and information concerning the fate and transport of septic effluent at Los Amigos Ranch, the conclusions and recommendations presented in the original report are reaff,rrmed. While there are important engineering aspects to the design of an on-site septic systenr that can be addressed to ensure effrcient septic-system operation in the Los Amigos Ranch development, geologic conditions are not favorable to prevent nitrate contamination of the ground water. The hydrogeologic conditions of the development site have not been adequately researched by the developer to justify the use of individual septic systems. If the Los Amigos Ranch development is to be permitted to utilize indivirlual septic systems, then the geologic and solute transport concerns discussed in the report should be fully addressed before such approval is granted. This would require the installation and testing of several nronitoring wells (shallow and deep) to specifically characterize the local hydrogeologic conditions. A solute-transport analysis will also be needed to accurately forecast long-term nitrate loading in the ground water. Such a study could be cost-prohibitive. The topography and proposed lot configuration of the development may not be advantageous for the use of a gravity-feed wastewater collection system. As a cost-effective alternative to the installation of several sewer-lift stations, the developer should consider using a low-pressure, small-diameter, variable-grade sewer-collection (SDVG) system which can be powered by individual grinder pumps. Simpler pumping systems may be feasible u'hen combined with the use of individual septic tanks to settle solids. 2420 Alcott Street, Denver, Colorado 80211 (303) 458-5550 Facsimile (303) 480-97 66 mwe@mwewater.com RONALD C.

Presented in the following paragraphs are (l) a response to comments by Resource Engineering, Inc. and (2) a discussion of the fate and transport of septic efluent. RESPONSE TO COMMENTS BY RESOT,IRCE ENGINEERING,INC. Water-Table Map IvI\ilE has examined additional well data as presented by Resource Engineering, Inc., and has amended the water-table map accordingly in Figures I and 2. As these figures show, the ground-water mound is present with an even greater peak elevation. So-called dry wells referenced by,Resource Engineering, Inc. (Wells No. 31, 32,and 4l; Permits No. 188402, 188403, and 188404 for Kindall Ranch) are shown in these tu,o figures. Review of the u'ell completion and test reports indicates that static water-level data were not reported and the geologic logs are vague. To presume these boreholes are dry based on this lack of information is premature. The fust two boreholes were drilled to a depth of 300 feet; the third borehole was driiled to a depth of 500 feet. Each borehole was dnlled using the air rotary method. Production testing was conducted in each open borehole and not in a cased rvell. None of the boreholes yielded measurable amounts of water from the air-lift tests. Circulation loss and./or lorv specific yield relative to the air-injection volume and air-lift velociry ma), account for the apparent lack of water production from each borehole. For these three boreholes, the static water levels are unlanorvn. Abandonment reports for these boreholes are not in the respective well permit files at the State Engineer's Office. If these boreholes still exist, the current static water levels in each hole should be measured. No record ofWell No. 51, also shown in Figures I and2, was not found in the State Engineer's Office files. The log of this borehole should be submitted to the State Engineer's Office. If this borehole still exists, the current static water level in the borehole should be measured. The reported static water level after drilling Well No. 46 (Permit No. 119503) was 300 feet. This water level is inconsistent with other nearby wells and is believed to be incorrect. A purnp installation report forthe well is not in the State Engineer's Office well permit file to veri$ this water level. The current static water level at the well should be verified. I I I I T T I I T I T T I T T I t T t Ground-Water FIow to Sorins Creek During the Garfield County Commissioners meeting on April 13, 1998, MWE illustrated and described the concept ofground-water flow from an unconfined aquifer to a perennial stream where the bottom ofthe aquifer is belowthe bouom ofthe stream shannsl. This steam-aquifer relationship is shown in Figure 3a and is similar to the hydrogeologic conditions that exist in Spring Valley. Unless a barrier to flow exists, all flow from the aquifer to the channel must be nonlinear, as shown in Figure 3a. MWE stated during the meeting that a ground-water mound exists in the basalt-capped upland area located south and west of Spring Valley and in the vicinity of the proposed Los Amigos Ranch development. The perennial flow of surface water in Spring Creek is maintained by ground-water flow to the channel from upland areas bordering both sides of the valley. Flow ocaurs because the potential energy head in the aquifer drives the water from areas ofhigher head to areas of lower head. Flows lines from the aquifer to the stream cha:rnel are perpendicular to the lines of equal water- table elevations, as shown in Figure 3b. No barrier to ground-water flow is known to exist in the viciniq, of Spriog Valley. According to &e Colorado Geological Survey (Kirkham and Widmann, 1997), the valley is a half graben (or down-thrown block) formed as a result of intense subsidence induced by dissolution of underlying evaporitic rocks. The basalt and sedimentary rock formations that underlie this valley and overhe the evaporitic rocks are likely fractured, highly permeable, and hydraulically interconnected. Geomorphically, the landscape of the area is a karst topography with sink or collapse structures. This type of topographl,is produced not by normal surface runoff, but by percolating ground $'ater. As a rebuttal to these remarks, Resource Engineering, lnc. presented tu,o illustrations to show that "one-sided" ground-water flow to a drainage can exist and that such is the case at Spring Valley. ln other u,ords, there is no ground-water flow from the basalt-capped upland area in the vicinity of the Los Amigos Ranch development to Spring Creek. Insfsad, Resource Engineering, Inc. suggests that ground water flou,s from Spring Vallel, southwesterly to the Roaring Fork River. The first illustration by Resource Engineering, lnc. is recreated in Figure 4 and shows ground-water florv to a dewatering trench that partially penetrates an unconfined aquifer with a sloping water table. Similar to Figure 3a, ground-water flow to the dewatering trench will be nonlinear. Assuming all ground water is removed from the trench, the water table will curve downward to the bottom of the trench from both sides. The water-table configuration on t}re left side ofthe trench will not be flat as drawn by Resource Engrneering, Inc. unless the trench fully penetrates the aquifer. However, in Spring Valley the creek does not fully penetrate the aquifer. Available weU records indicate the aquifer beneath the creek is over 100 feet thick. Therefore, this illustration is not applicable to the hydrogeologic system known to exist in the Spnng Valley area. The second illustration by Resource Enginecring, Inc. (Figure 5), Inc. depicts a site investigated by the firm where ground water reportedly discharges as springs and seeps into a lowland (or valley) from one side and I I t I I I I I T I T T I I T T I T T orits as perennial streamflow. At this site there is no surhce evidence of ground-water discharge from the opposite side ofthe valley. In order forthis condition to exist, the ground-water seepage must be the emergence of a contact spring where permeable rock units overlie rocks ofmuch lower permeability. A lithologic contact is often marked by a line of springs, which may be either in the main water table or in a perched water table. The underlying layer need not be impermeable, merely that the difference in hydrautic conductivity be great eirough to preclude the transmission of all of the water that is moving through the upper horizon (Fetter, I 994). As statod above, Sprirrg Creek does not fully penetrate the aquifer and the strearn cbannel is not underlain by relatively impermeable rocks. Instea4 the creek is underlain by permeable lake deposits, fractured basalt, and fractured Maroon Formation interbeds of sandstone, siltstone, and shale. Therefore, this illustration is not applicable to the hydrogeologic syst€m lnown to exist in the Spring Valley area. Perched Water Table Resource Engineering, lnc. proposed that the local well data may indicate the presence of a perched water table in the basalt upland area near tle Los Amigos Ranch development. There are insufficient data to confirm this. Nevertheless, a perched water table can exist in basalt formations because of the hydrogeologic character of the rock material. This h1'drogeologic character of basalt is described in the follor.r'ing paragraphs. FATE AND TRANSPORT OF SEPTIC EFTLIJENT Permeability and Porosity of Volcanic Rocks Volcanic rock form as a result of solidification of magma at or nqtr the ground surface. In a hydrogeologic sense, these rocls generally differ from most other crystalline rocks in that they have primary features that cause permeability within otherwise-solid rock mass. As described below, these features are related to the history of the rocks. When magma extrudes to the ground surface and flows as lava, the rocks that form on cooling are generally very permeable. At the surface, rapid cooling and escape of gasx causes cooling joints and bubble-like pore spaces. While the lava is in motion, a crust forms on the upper surface as cooling takes place. Flow of the lava beneath the crust causes it to become fractured, producing a blocky mass of rock that is commonly pulled under the leading edge of the lava flow. The final result is a solid mass which in many places has coarse rubble zones above and below more dense rock. The blocky rock masses and associated gravel interbeds produce a bulk permeability that is very high in most young basalts. Alteration of deeply buried basalt or by the influx of cementing fluids during geologic time causes the permeability to decrease (Freeze and Cherry, 1979). I I I t T T I T I I T T t t T I I I t In geologic terms, the Tertiary basalt beds in the Spring Valley uea are recent deposits. Some recent basdt aquifers have close to the highest trensmissivities known @avis and DeWiest, 1966). Ground water may be difficult to develop from basalt aquifers, even though ransmissivities of recent basdt flows are high, because ground water drains freely to points of discharge at str€ms and the depth to ground water may be excessive or water may be locally absent. To find ground water in basalt, attention must be paid to locating'impermeable' zones. The porosity of unfractured basdt is generally less than one percent. Dense massive lava-flow rock will have I to l0 percent porosity. Permeability is largely a function of other primary and secondary structures within the rock. As shown in Figure 6, features creating high K in basalt include: @lumnar joints caused bY cooling, lava tubes, vesicles that intersect, tree molds, Aactures caused by buckling of partly congealed lava, and voids left between successive flows @igure 7). In the Spring Valley area, permeability is also enhanced by collapse fractures and faults caused by subsidence induced by dissolution of underlying evaporitic rocks and regional folding. Porosity may be increased locally and near the ground surface due to weathering. Buried soils (paleosols), a common feature in thick sequences of volcanic rock, can form local horizons of "perched" ground water. In areas of extensive volcanism, a basin that is undergoing sedimentation may contain complicated sequences of alluvial, volcanic, and lacustrine material. The basalt deposis in the Los Amigos Ranch development are interbedded with alluvial deposits. Volcanic rock in which interbedded sediments (or pyroclastics) are absent will have relatively low porosities if large volumes of rock are considered. Although reliable mqsuremens of bulk density are not found in the literature, the rapid rise in water levels reported in areas recently put under irrigation indicates that the porosity can be less than 5Vo in 4 I I T I T t T I T I I I t T I t I I I volcanic rocts which are good to excellent aquifers @avis and DeWiest, 1966). Aquifer tests made in the Snake River Basalt of Idatro yielded storage coefficients of 0.02 and 0.06, which would suggest an effective porosity of less than l0 percent, provided that the aquifer in the tests wils entirely unconfined. Sedimens (interbedded) with the lava will greatly increase the average porosity of large volumes of rock that arepredominantly volcanic. Under favorable circumstances the interbdded sediments provide storage space for the water whereas the more permeable volcanic rock conducts the water to the wells. The hydraulic conductivity of various types of basalt will likely range from 0 to 2,400 ftlday. Horizontal permeability will be due to spaces between lava-flow events. Vertical permeability is largely due to fracturing of partially solidified lava in the late stages of movement together with shrinkage cracking. Commonly, vertical permeability is very small in comparison to horizontal permeability. If the basdt beds are tilted by tectonic movement after they have been deposited (such as in the Los Amigos Ranch development area), septic effluent movement in the unsaturated zone of the basalt will be down-dip berween the lava flows as schematically shown in Figure 9. In the Los Amigos Ranch development area, this percolation will be in a northeasterly direction until the water table is encountered. Therefore, ttre possibility may exist for some septic emuent from the development to emerge in Spring Valley. In general, "pahoehoe" flows ffigure 6) are much more permeable than are dense interior portions of thick "aa" flows. The upper and lower parts of the aa flows may be brecciated and quite permeable. Buried soils and ash beds may form semi-horizontal barriers to outer movement. Owing to the extreme high permeability of some volcanic rocks, biological contamination is a potential danger @avis and DeWiest, 1966). On a large scale, the permeability of basalt is very anisotropic. The centers of lava flows are generally impervious. Buried soils that produce high permeability develop in the top of cooled lava flows. Stream deposits occur between the flows. The zones of blocky rubble generally run parallel to the flow trend. The direction of highest permeability is, therefore, generally parallel to the flows. Within the flow, the permeability is normally greatest in the direction of the steepest original dip of the flows (Freeze and Cherry, 1979). This is shown in Figure 8. Ihansport of Contaminants in Porous and Fractured Rock The physical processes that control the movement of a dissolved, nonreactive ground-water contaminant (such as nitrate) through soil and rock is advection and hydrodynamic dispersion. Loss of nitrate mass in soil or rock is negligible except in unusual high-reducing ground-water conditions. Advection is the component of solute movement attributed 1s 6ansport by the flow of ground water. The rate of transport is equal to the average linear ground-water velocity. Hydrodynamic dispersion occurs as a result of I I t I T T I I I I I I t I T I t t t mechanical mixing and molecular diffrrsion (Freeze and Cherry, 1976). Dispersion is the spreading of a solute as it moves through a porous medium. The net effect of the dispersive phenomena is to decrease the concentration gradient between two different solutions of the same solute. In essence, dispersion reduces the sharp interface between the two solutions (Knox, et al., 1993). The heterogeneity of most geologic materials introduces irregularities of flow with the consequent effects on the mixing of the contaminant, which often far overshadow the effects of microscopic dispersion. Heterogenelty of the aquifer and irregular geometries of ground-water recharge and discharge zones, together with the lack of specific data on aquifer characteristics, preclude quantitative evaluation of dispersion coefhcients ("dispersion configuration") for most natural ground-water flow situations. In general, the magnitude of dispersion for uniform sands can be measured in terms of only a few feet over a travel disunce of 1,000 feet @reeze and Cherry, 1976). This is schematically illustrated in Figure lOa which shows the shape of a contaminant plume from a continuous point source. In saturated flow through porous media, velocities vary widely across any single pore, just as in a capillary tube where the velocity distribution in laminar flow is parabolic. ln addition, the pores possess different sizes, shapes, and orientations. As a result, when a contaminant is introduced into a flow system. it spreads gradually to occupy an increasing portion of the flow region. This is a nonsteady, irreversible mixing process by which the contaminant disperses within the surrounding water. Hydraulic conductivity has a direct influence on the seepage velocity in a saturated formation. Consequently, it will also have a direct impact on the transport of contaminants in the subsurface. Spatial variability in hydraulic conductivity is a critical factor controlling mass transport. Spatial variability of subsurface solute movements is derived mainly from the variability of the hydraulic conductivity. Thus, heterogeneity in an aquifer system has a pronounced effect on contaminant migration (Knox, et al., 1993). Fractured formations, such as basalt, can be viewed as a solid rock matrix, typically with a low permeability, that is cracked or fractured. Owing to the low permeability of the rock matrix, most fluid flow through the formation will be through the interconnected fracture channels. The velocity of fluids moving through fractures has traditionally been approximated using the so-called cubic law which was developed from the study of nonturbulent flow of a viscous, incompressible fluid between two parallel plates. The average velocity parallel to the planar surface is developed using Darcy's Law and the equivalent hydraulic conductivity. Iongitudinal dispersion in the fracture is significant for low velocities. This is schematically illustrated in Figure 10b which shows the shape of a contaminant plume from a continuous point source in fractured rock. Fracture spacing can have a significant effect on the advance rate and ultimate penetration of a contaminant (Knox, et al., 1993). I t I T T I I t t I I I T T I T T t T Fate and Tfansport of Septic Effluent Each individual septic leach field in the Ios Amigos Ranch development will become a continuous point source of nitrate contamination. The concentration of nitrate in the effluent seepage will be a function of the biological denitrification capacity of the leach-field soils (Iong, 1995 and Cantor, 1997). Denitrification is the biological reduction of inorganic-nitrogen to nitrogen gas. Coarse soils will inhibit the denitrification process. As long as carbon and dissolved oxygen are available, nitrification (or the oxidation sf ammsnium-nitrogen to nitrate) will be present. In typical on-site septic systems, oxygen availability is the most important factor affeaing nitrification (Long, 1995). Nitrate is typically more mobile in the subsurface environment than ammonium-nitrogen. When niuate reaches ground water, it becomes very mobile because of its solubility and anionic form. Nitrates can move in ground water wirh minimal transformation. They can mi$ate long distances from input areas if there ue highly permeable subsurface materials that contain dissolved oxygen (Canter ,1997). From the individual septic leach fields in the Los Amigos Ranch development, ammonium-rich effluent will percolate vertically until it encounters the basalt bedrock. Each leach field will be comprised of a few feet of natural or imported soils within which some denitrification may occur. At the soil-basalt conract, the effluent seepage will likely change course and flow down-slope to the southwest until it encounters one or more vertical joints or fractures in the basalt, or until it emerges as a local contact spring. Unsaturated flow within the basalt will likely occur along very permeable bedding planes that separate the individual lava flows and through joina and fractures, as schematically shown in Figure 9. These beds dip in a northeasterly direction. As the effluent percolates through the unsaturated zone, it will undergo nitrification. The nitrate plume from each point source will likely appear similar to Figure lOb. Within the fractured rock formations beneath the Los Amigos Ranch development, uniform mixing of the high-nitrate effluent will not occur, as proposed by the developer. This further indicates that the developer's forecast average concentrations of nitrate in the ground water beneath the property are not applicable to the hydrogeologic conditions that are present. A low specific yield of the aquifer (likely in the range of I to l0 percent) and the planned close spacing of the individual septic systems (one per every 3.1 acres average for 164 residences) will likely compound the contamination concern. The notion proposed by Los Amigos Ranch that the density of septic systems in the development will be l0 acres per individual septic system because of open space is spurious. The lO-acre figure would be valid only if the open space is eliminated and the lots are re-platted to be l0 acres each. Concentrations of nitrate in the ground water will be variable because of the geologic factors discussed above. As reported by Ford, et al. (1980), this phenomenon has also been observed in the mountains of Jefferson County, Colorado. Geologic factors are significant in explaining the occurrence of contamination l: l: lr l: lr lr lr I T T t I in well water' aad they are difficult to deal with in mouDtainous environmeas due to the variation in the dep& to bedrock, fraca[e direction, specific yield of the aquifer, and other factors that defy easygenerdization. Geological considerations may arso explain coriform contrmination when weil construction is adeguate' Ford, et al.(1980) noted that fractures in crystalline bedrock are not effective in filtering the bacteria associated with waste effluent. Moreover, orientation of the rock fractures does influence the direction and travel path of the contaminants. This indicates that simply locating a well at an elevarion above the wastewater source does not provide any assurances that Ieachfield effluent will not flow into the well. CONCDUSIONS AND RECOMMET\DATIONS 1' Based upon a review and analysis of additional well data in the project area and the foregoing discussions concerning the fate and transport of septic effluent at Los Amigos Ranch, the conclusions and recommendations presented in the original report are reaffirmed. 2' while there are important engineering aspects to the design of an on-site septic system that can be addressed to ensure efficient septic-system operation in the Los Amigos Ranch development, geologic conditions are not favorable to prevent nitrate contamination of the ground water. 3' The hydrogeologic conditions of the development site have not been adequately researched by the developer to justify the use of individual septic systems. If the Los Amigos Ranch development is to be permitted to utilize individual septic systems, then the geologic and solute transpon concerns described herein should be fully addressed before such approval is granted. This would require the installation and testing of several monitoring wells (shallow and deep) to specifically cbuacter'ae the local hydrogeologic conditions. A solute-transport analysis will also be needed to accurately forecast long-term nitrate loading in the ground water. Such a study could be cost- prohibitive. 4' The topography and proposed lot configuration of the development may not be advantageous for the use of a gravity-feed wastewater collection system. As a cost-effective alternative to the installation of several sewer-lift stations, the developer shourd consider using a low-pressure, smalldiameter, variable-grade sewer-collection (sDVG) system which can be powered by individual grinder Pumps. simplerpumping systems may be feasibre when combined with the use of individual septic tanks to settle solids. - 8 ll :l rl rl ll I T I I l I lr Ir lr Ir lr I T I T T T In,iltralion to groundwater table --l Figure 3a.
