RE: Los Amigos Ranch PUD Filings 6 - 1O lndividual Wastewater Treatment Systems
Dear Greg:
This letter is provided as supplemental information to previous letters by Resource
Engineering, lnc. (Resource) related to ISDS systems for the Los Amigos Ranch PUD
Filings 6 - 1O (LAR). Those letters are addressed to Los Amigos Ranch Partnership and
are dated April 6, 1gg8t and April 23, 1998. The April 23 letter is attached hereto as
Exhibit A. The purposes of this letter are:
1) To place the Los Amigos Ranch PUD Filings 6 - 1O into perspective' This is
brief overview of our letter of April 23'd and the reader is directed to that letter
for further detail.
2l To summarize and comment briefly on the professional opinions that have been
made related to the proposed Los Amigos Ranch ISDS systems, both those in
favor of the ISDS systems and those opposed to lsDS systems.
3) To reiterate and further support the opinion of Resource Engineering, lnc. that
properly designed, installed and maintained ISDS systems will not present
adverse health and environmental impacts and are a suitable method of
wastewater treatment for the Los Amigos Ranch PUD Filings 6 - 1O
LOS AMIGOS ISDS SYSTEMS IN PERSPECTIVE
o Los Amigos Ranch PUD proposes 168 ISDS systems on 1 ,7OO acres' This is
a density of 1 unit per 1O acres. The development is linear in nature, extending
approximately 2.5 miles from the entrance to Filing 6 to the northwest corner
of Filing 9.
. The minimum distance between a proposed ISDS system and a drinking water
supply is approxim ately 2,2OO feet(Spring Valley Wells) and 2,500 feet (County
Rd. 1 14 - HwY 82 wells).
. The depth to the regional groundwater in the Los Amigos Ranch Development
area is great based upon available well data: ranging from 6O feet (apparent
perched water table) to possibly more than 800 feet'

o Other subdivisions we have reviewed in Garfield and Eagle Counties in generally
similar geologic settings have no nitrate contamination problems in their drinking
water supptLs. The five subdivisions reviewed (Wooden Deer, Panorama
Ranches, Kings Row, Red Table Acres and Aspen Mesa Estates) are underlain
by hasalt, utiiize predominantly ISDS systems (some systems are evaporative
where leach fields were inappropriate), and have public water system wells
within the developments. The highest nitrate level reported in any of these four
subdivisions is 2.3 mg/liter, less than l/e the State and EPA drinking water
standard. The drinking water wells in all these developments are much closer
than 2,20O feet from the nearest ISDS system. Please refer to the April 23
letter for additional detail.
. A study conducted in the mountain residential areas of Jefferson County,
Colorado2 (fractured bedrock conditions) found a strong correlation between
nitrate levels in drinking water wells and the setback distance from potential
contaminant sources such as leach fields. The study found that,
,ln particular, zones of nitrate contamination greater than
lomg/titerwerefoundtobeassociatedwithhousing
densities greater than one dwelling unit per acre and with
well protective distances of l OO feet or less"
The study further concluded that,
,statistical anatysis of the study data indicates that, for
similar mountainous terrain, residential development that
provides for well protective distance of only l0o feet face
a 21.8% probability of exceeding the NOt-N health
standard; whereas, the probability with a well protective
distance of 2oo feet is 9.4%. Thus a minimum protective
distance of 200 feet is more reasonable than 100 feet in
preventing nitrate heatth hazards'''
This study establishes a 200 foot well protective distance as more reasonable
than a 100 f oot distance f or protection from nitrate contamination. This
compares with a 2,2oo+ foot setback from drinking water supplies in the Los
Oualitv, Ford, Schott and Keefe, Journal of
November/December, 1 980.

SUMMARY OF OPINIONS PRESENTED
1) Resource letter of Februarv 28. 19983. This letter presented our initial opinion
that ground*"t", ttow in the ten development area is toward the Roaring Fork
River and not toward Spring Vatley. lt concluded that it is unlikely that LAB
ISDS systems will contaminate the regional groundwater system (where
contamination is defined as nitrate levels at or above the State and EPA
drinking water standard of 1O mg/liter). This opinion was arrived at based on
the geology and hydrogeology of the site, information on wells in the LAR'
Spring ValLy and HWV 82 - County Rd. 114 arca, and a mass balance
approach using reasonable engineering assumptions'
This letter resulted in a planning and Zoning Commission condition of approval
for LAR stating:
"ThatpriortotheapprovaloftheBoardofCounty
CommissionersofthePreliminaryPlanforLosAmigos
Fitings6-1o'theapplicantshalldevelopagroundwater
qrriitv monitoring plan and mitigation plan' or in the
alternative, develop a new proposal that eliminates the
need for a monitoring and mitigation plan, to be reviewed
and recommended for approval by the County's
consulting engineer-'
2l Resource letter dated Aoril 6. 1998. This letter was prepared to present a new
proposal "r r"qrir"O Uy P&2. The new proposal included the utilization of
properly designed, properly constructed and properly maintained individual
wastewater treatment systems. ln order to ensure this, Los Amigos Ranch
partnership agreed to implement Design Standards and a Management Plan for
individual wastewater treatment systems. These included:
a) Use of septic tank effluent filters. These eliminate the deposition of
nitrogen rich bio-solids from septic tanks to leaching fields.
3This letter was previously introduced to the Board of County Commissioners at the
hearing on April 13, 199b where it was included as an attachment to the Resource letter dated
April 6, 1998.

Use of leach field dosing systems. Dosing systems, by intermittently
discharging slugs of efflu-entto the leach field, promote even distribution
of effluent throughout the leach field. This eliminates the consistently
saturated zones commonly found in "traditional" septic tank leach field
systems. Dosing also promotes the cyclical aerobic / anaerobic
conditions needed for the nitrification - denitrification process'
Annual individual wastewater system inspections performed under the
authority of the homeowners association. These inspections will ensure
proper system maintenance and identify failing systems so repairs can
be made.
The new proposal was based on the opinion of Resource Engineering, lnc' that:

County's consultant, prepared a letter regarding Los Amigos Preliminary Plan -
ISDS impact. The letter concludes:
'... the total, cumulative and diluted, concentration of
constituents in the regional groundwater aquifer is
estimated to be less than state and EPA drinking water
aGroundwater contamination for purposes of this opinion is defined as an increase in
the nitrate level of the groundwater undeilying Los Amigos Ranch and surrounding properties

likely occur if individual septic syste/ns are used in the

While the report concludes that nitrate levels may exceed the primary drinking
water standards in some areas (e.g. immediately adiacent to a leach field) it
does not state nor conclude that there will be contamination exceeding the
pri."ry drinking water standards at any drinking water wells.

from the nearest Los Amigos well. lf this map is correct, the effluent from 15
ISDS systems located orrer Yz mile away is a very small component of the
groundwater flowing to the wells and will not create a nitrate contamination
problem at the Uos Amigos of CMC wells. lt is our opinion that this map is not
correct and that no LAR ISDS systems are tributary to Spring Valley'
It is our opinion the groundwater contour map prepared by MWE is a flawed
interpretation of the lroundwater regime as it does not account for available
well data that is clearly contrary to the map. MWE concludes that there is a
significant groundwater mound centered to the northeast of the LAR proposed
development area. The apex of the mound is mapped showing the water table
approximately 1OO feet below the ground surface. This discounts 7 wells in the
atea, ranging in depth from soo to over 800 feet, only one of which
encountered water and that at a reported depth of 320 feet' Refer to
Attachment A to the Resource letter of April 23, 1998 for a map of these
wells.
ln our opinion when this well data is considered, the MWE map is shown to be
clearly incorrect. lf a groundwater mound does exist, the apex of the mound
has to be within, or very near the edge of Spring Valley and not centered on the
mesa above Los Amigos as suggested by MWE'
5) Addendum No. 1 to MWE reoort in (4) above. This report was prepared by Mr'
John Kaufman in rebuttal to "on*"nts made at the Garfield County Board of
County Commissioners hearing on April 13' 1998'
Mr. Kaufman states:
"MWE has examined additional welldata as presented by
Resource Engineering, lnc. and has amended the water
tahle map accordingty in Figures I and 2' As these
figures show, the ground-water mound is present with an
even greater Peak elevation.'
This remapping appears to be based on, and follow, more consistently than
previous MWE mapping, the topographic land surface. The mapping does
ieduce the number'ot ISOS lots tributary to the Spring Valley wells from 15 to
8 * (by Resource count). However the mapping continues to discount the
available well information which clearly shows a much greater depth to
groundwater. The discounted well information is either deemed incorrect where
information in the State's files contradicts the MWE opinion or invalid where the
limited information in the State's files has been supplemented with information

from the driller's files. Mr Kaufman states:
May 13, 1998
.So-calleddryweltsreferencedbyResourceEngineering,
lnc. (Wells No. 31, 32 and 41; Permits tr/o' 188402,
188403, and 1884O4 for Kindall Ranch) are shown on
these two figures. Review of the well completion and
test reports indicates that the static water- level data
were not reported and the geologic logs were vague' To
presume these boreholes are dry based on this lack of
information is Premature.'
Mr. Kaufman {urther states:
,The reported static levelafter drilling well No. 46 (Permit
No. 1 19503/ was 3OO feet. This water level is
inconsistent with other nearby wells and is believed to be
incorrect.'
ln Mr. Kaufman's oral testimony before the Board of Commissioners on April
13, 1998 he stated:
'l have researched every legally drilled well or bore hole,
test hole, out there ... at the Sfate Engineer's Office' l'm
not aware of a number of holes referenced in the other
consultant,s report. That raises a serous question about
the lawfulness of those boreholes to begin with.'
The status of these wells has been thoroughly documented in the Resource
letter dated April 23, 1998. ln our opinion continuing to discount this important
well information is a serious flaw in the MWE analysis. When these wells are
considered one !!USl! arrive at a different interpretation of the groundwater
regime than that Presented bY MWE.
Finally, it should be noted again that the MWE addendum does not conclude
that there will be contamination exceeding the primary drinking water standards
at any drinking water wells.
6) Jerome Gamba and Associates. lnc. letter dated Aoril 21. 1998. This is a one
page letter prepared by Jerome Gamba, PE for Colorado Mountain College. Mr.
Gamba provided a review of the April 10, 1998 MWE report'
Mr. Gamba concludes:

'Every effort should be made to convince the Garfield
County Board of Commissioners that any waste water
discharged to the (Spring Valley) aquifer' from this time
forward, must first receive tertiary treatment so that the
discharged effluent can virtually meet drinking water
standards.'
What Mr. Gamba does not say is very important. Mr. Gamba does not conclude
or infer that any of the LAR ISDS systems are tributary to the Spring Valley
aquifer. He does not state or infer that there is any possibility of contaminating
the Spring Valley aquifer from ISDS systems in Los Amigos Ranch. ln fact, Mr.
Gamba does not mention Los Amigos Ranch ISDS systems at all.
7l Bishoo Broqden and Associates letter dated Aoril 23. 1998 (attached hereto
as Exhibit Bol. Mr. Brogden was retained by LAR to review and comment on
the work and opinions prepared by Resource and MWE. Mr. Brogden prepared
a groundwater contour map including the well data dismissed by MWE and
concluded the following:
1. 'The direction of groundwater flow is not towards a
group of wells that provides or will provide the water
suppty for the Los Amigos Ranch development and the
Colorado Mountain College.'
2. "Return flows from the filings 6 through 10 in the Los
Amigos development will not migrate towards the wells;
instead the return flows willmove southwest towards the
Roaring Fork River.'
Mr Brogden states in summarY:
'ln summarY, our mapping of the ground water system in

CONCLUSIONS AND OPINION OF RESOURCE ENGINEERING, INC'
. None of the technical reports provided by consultants, both those representing
LAR ISDS p.pontnts and those representing LAR ISDS opponents' indicates
that ISDS'systems in Los Amigos Ranch PUD Fitings 6 - 10 will result in
groundwater nitrate concentrations in drinking water supplies that exceed State
and EpA orint<ing water standards. No consultant involved in these proceedings
has concluded otherwise'
. ln our opinion the MwE analysis of the groundwater regime in the Los Amigos
Ranch vicinity is flawed as it discounis available groundwater data that is
contrary to inlir opinion. While MWE concludes that somewhere between 5%
and 9% of the 168 lots in filings 6 - 10 are tributary to Spring Valley we
continue to be of the opinion, baJed on our analysis and supported by Brogden
and Collins, that none of the lots proposed for ISDS systems are tributary to
Spring Valley, the Los Amigos Ranch water supply and the CMC water supply'
o ln our opinion, properly designed, installed and maintained ISDS systems are an
appropriate and effective method of wastewater treatment for the Los Amigos
Ranch PUD filings 6 - 10.

6-10 lndividual Wastewater Treatment Systems
Dear Greg:
This letter is provided as supplemental information to our previous correspondence
regarding the proposed Los Amigos Ranch PUD individual wastewater treatment systems
(lSlDS). -That correspondence is contained in a report dated April 6, 1998 titled @
Amioos Ranch PIJD individual Wastewater Treatment Svstems Groundwater lmoact-
tn the past few weeks the discussion surrounding the use of ISDS systems at Los Amigos
Ranch PUD has been elevated to a theoreticat, academic plane in which there has been
much discussion about hydrogeology and contaminant transport in complex geologic
systems. Much of the theoretical discussion has been presented by Mr. John Kaufman
oi M"L"rghlin Water Engineers, Ltd. from his experience in other regions and in his
reiteratiori and interpretation of work by Kirkham and others. While some of Mr
Kaufman's points are relevant, we are concerned that by moving the focus of the
discussion toward theory, we are ignoring the actual conditions observed at Los Amigos
and thus losing sight of the impact of the project.
A recap of the project and the site conditions is appropriate:
1) There are 168 ISDS systems proposed for 1,7OO acres. This is a density one unit
to 1O acres.
2l The minimum distance between the proposed ISDS systems and a drinking water
supply is approximately 2,OOO feet (Spring Valley wells) to 2,500 feet (County Rd.
114 - Hwy 82 wells).
3) The depth to the regional groundwater is great: ranging from 60 feet (perched
water table conditions) to possibly as much as 800 feet.
The site setting fits well with my professional understanding of what is generally thought
of as an acceplable location tor iSOS systems. The conditions (depth to groundwater and
distance from significant water supplies) suggests that this may be one of the better
locations and project configurations for ISDS in Garfield County.
The balance of this letter is presents information emphasizing the reasonableness of the
ISDS proposal that has been made. lnformation presented in this letter covers four
general areas:
Confirmation of welt data available for the Los ,Amigos development area.
Groundwater impacts from other subdivisions in Garfield and Eagle Counties that
utilize ISDS systems and that are located in geologically similar settings.
Groundwater mixing and implications for drinking water quality.
Discussion of leachJield - well setback distances and the implications for water
quality.

The information included in this letter does not, nor is it intended to provide additional Los

is pr6vidEO to support our previous conclusion that individual-sewage treatment systems

conclusion and assert that properly desilned, installed and maintained individual septic
tank - leachfield treatment systems ari a reasonable and prudent manner of sewage

Confirmation of Well Data
Attachment A to this letter provides supplemental data regarding the status of wells in the
1oi emigos development area. lncluded is Figure 1 that was attached to our Feb. 28,
l ggB letter. The figure has been modified to include the State Engineer's well permit
numbers under which the wells were drilled except where otherwise noted. Also included
in Attachment A are printouts from the State's well data base in support of the map.
Additional informaiion-proriO"O by Shelton Drilling on several of the wells constructed by
Shelton Drilling is also included.
Two wells noted on Figure 1 indicate the possible presence of localized perched water
table conditions at seiarate locations. This is seen by two wells repofting relatively
shallow depths to water (1 1g feet and 60 feet) as compared to the o.ther much deeper dry
holes. These *efislpplar to be hydraulically connected to nearby srnall springs that
discharge from the base of the basalt on the southwest side of the development. The
springs-nearby wells are the only known springs on the Los Amigos Banch property.
The well information supports a finding that the regional groundwater table in the Los
Amigos Ranch vicinity is'very deep arid trends welterly or southwesterly toward the
Roar'ing Fork River andis contiolled, ultimately, by the Roaring ForkEive.r. lt also supports
a findi-ng that there are two localized perched water tables defined by the localized
geology-in the immediate vicinity of the springs and two shallow wells.
Groundwater Ouatity in Water Wells Serving Other Subdivisions
Attachment B includes water quality information for four subdivisions on Missouri Heights
that use ISDS systems and have community drinking water wells located within the
subdivisions. n 'map tFigure 2) is also included showlng the. general location of these
subdivisions. While the ipecific densities within these subdivisions in unknown, it is my
lGroundwater contamination for purposes of this opinion is defined as an increase in the
nitrate level of the re;io;al groundwater undertying Los Amigos Ranch and surrounding properties
to a level above thi drink-ing water standard oi t o mg/liter as established by the Colorado
b"p"nnlrnt of public Health Jnd Environment and the U.S. Environmental Protection Agency.

understanding that the densities range from several acres per lot to Ies-s than one acre per
lot. plats weie not reviewed for thG analysis to determine the specific density.
As can be seen in the attached water quality data none of the four subdivisions r€port
elevated nitrate levels that would be of concern. The highest level of nitrate reported in
any of these four subdivisions is 2-3 mg / liter.
The four subdivisions were chosen as they are underlain by basalt formations and they
have public water-systems for which water quality data is available from the colorado
O"purt*.nt of Health. The basalt formation also makes them somewhat analogous to the
Los Amigos geologic setting.
The lack of groundwater contamination immediately under these four subdivisions with
ISDS systrrnr rrggests tnat it is improbabte for Los Amigos to adversely impact
groundwater several thousand feet away.
This analysis is not rigorous, nor is it intended to be. lt does however, show examples of
similar situations in -wnicn ISDS systems have had no apparent negative impacts on
groundwater qualitY.
Groundwater Mixing in the Vicinity of a Well
Speculation was raised by John Kaufman of McLaughlin Water Engineers that zones of
grornd*"ter with concentrated nitrates may exist in the groundwater under or adiacent
io tos Amigos as a result of poor mixing in the groundwater. We agree that mixing may
not be imm6diate or uniform. However [nowledge of groundwater behavior in the vicinity
of wells indicates that mixing will increase and beCome more and more complete as
troundwater is drawn towards a well. Complete mixing will occur, certainly, within a
pumped well.
As groundwater is drawn towards a well the gradient of the water table increases
(ste6pens) and the velocity of the groundwater moving through the aquifer increases (more
water moves through less space). As the velocity increases more and more mixing will
occur and complete-mixing will occur in the well. lt is unlikely that discrete components
oi tn" groundwai.i tf o* fraving high nitrates could result in high nitrates at a well as a
result oi unmixed flow. This iJparticularly true for existing producing wells.
ln summary, while it is possible to have areas within the groundwater regime of higher
nitrate concentrations, niixing will occur within the radius of influence of a pumped well'
Therefore we believe our p-revious assumption that there is complete mixing of the
gio;nO*rter is valid for determining the impacts to other drinking water supplies.
Discussion of Leachfield - Well Setback Distances'
A study conducted in Jefferson County, Colorado published in 1980 reviewed water well
contamination as a function of separation from contaminant sources (leachfields). The

leichfields were found to have nitrates greater than 1O mg / liter. At a_ distance < 210
tiei onlv one well out of 13 sampled ha-d a nitrate level greater than 1O mg / liter. The
riuOy found r rtrong correlation between nitrate concentration and well protective
distance where *.tt-p.t.ctive distance is the distance a well is separated from a
leachfield.
while not absolute, the probability of nitrate contamination decreases as wells are moved
further and further horizontally fiom leachfields or other possible contaminant sources.
The study concludes:
'When nitrate concentrations for the study area were spot mapped, the
localities of excessive nitrate contamination were seen to be associated
with increased housing density. tn particular, zones of nitrate
contamination greater tian 1O mg/liter were found to associated with
housing densities greater than one dwelting unit per acre and with well
proteciive distances of lOO feet or /ess.'
.Statistical analysis of the study data indicates that, for similar
mountainous teirain, residential development that provides for well
protective distance of only lOO feet face a 21.80,6 probability of exceeding'the NOr-N health standaid; whereas, the probability with a well protective
distancb of 2OO feet is 9.4%. Thus a minimum protective distance of 2OO
feet is more reasonable than l OO feet in preventing nitrate health hazards-'
ln Los Amigos, the minimum drinking water wells separation from ISDS systems will be
"ppr*i.rtity Z,OOO feet (Spring Valley wells) to 2,500 feet (Cty Rd 1 14 - Hwy 82
*Jfrt. The findings outlined in tni Ford ieport, together with the physical separation at
Los Amigor rrgg.its that the possibility of nitrate contamination at Los Amigos is very
slight.
Summary
ln summary it is the opinion of Resource Engineering, lnc. that individual septic disposal
systems that are properly designed, properly installed and properly maintained are
ipproprlate for Los'Amigos anO iitl notresult in contamination of groundwater drinking
suipfils as defined herein. Therefore we recommend approval of ISDS systems.

Dear Mr. Boesker:
tr,Ir, John Cunier of Resource Engiucering asked that we review iaterprctations by his fircr and by
Mr. John IGutuan of the $ound watcr syst€m in the Spring Valley area, and providc you with our
written commests on thosc intcrprAations. We understand tbat some conccrn has beeu raiscd gbout
the moveraent of nitrates from individual septic systems imo the golrnd water systeE. We studied
rhe reports prcpsrcd by bmtr conpiulics such as a l€ttsr from Resourcg Fnginesring dated February
28, 1998 aud a rcport by Mt. John lkufman with Mclauglrlin Watsr Engineers titlsd, 'Los Astigos
Raach PUD, Potential loprcts on thc Crround.Watcr Fiow and Quality Due to the Use of Individual
Scptic Systems for Domestic Wastewatcr Treauaent and Disposal", dated April 1998. Both rcports
e:<amine tbc ground water systcm in the Spring Valley and both prcsent waGr lewl infornration that
can be used to describc the configruation of the upper watcr levels in the area.
Geolory eud llydrolory
The geology beneath Spnng Valley is dEscribed as a scries of basalts, intcrbedded wi& alluvial and
lake-bed deposits that overlie the Maroou Formation. At thc surface in Spring Valle), arE presEot-
day alluvial asd lske deposits that probably are sirnilar to the deposits found at depth bcttffccn
individual basalt florrs. Grourd wuer is present in the area aad can be found in the geologic usits;
iR occurrence is courolled by scvcrEl factors irr.luding:
1. The presence or absence of permcability in the gcologic units;
2. l.ocatious of discbargc sucb as Red Canyon, Cattle Creek and the Roaring Fork Rivsr
aud their tribuwies;

oru intcrpretation of thc $ound water systcm difftrs ftom lr4r' Kaufirran's interpetation in that he
mapped a ground water riound in ricilt;if,til*ie9s. .Wc believe that therc is not a oound in
this area. but instead an isolatcd -n. oi zones of pcrcbed gro,nd wa]l overlytng a deep $ound
t,/Etcr systsm. This intcp,retatioa is zupportcd by the nt-'"'L rcported dry holes in the area' which
indicate that the *giootf grognd watir'is deep and a shallow gfound water mound is not present'
From this effort, wc csn conclude thc following:

Mountain Collcge;
Z. Rcturn flows from iilings 6 through 10 iu tbc Los Amigos development will not

This report is essentially a slight refinement of the submittal dated Aprl'Z7 ,1998. It contains a few
minor corrections. ,.ririo*I and amplifications, as well as definitions of technical terms that were
omitted from the first report due to iime constraints. Definitions are themselves simplified to the
extent possible to avoid having to further define terms used therein. For precise technical definitions
I refer you to the Dictionory i7 Ufring, Mineral, and Related Terms (2"d ed., U.S- Bureau of Mines'
1996), or the Glossary of Giolog/ ind Related Sciences (American Geological Institute, 1997)'

I have also relied heavily on personal communications with Robert Kirkharn, of the colorado
Geological Survey, who iras several years of experience in detailed mapping of the geology o-f the
Roaring Fork Valle y are6- as well as on my own knowledge of the area, where I have lived and
worked intermittently since 1968.
The Los Amigos Ranch occupies roughly the southwestern half of the northwest-southwest-trending
oval mesa delineated by Red b*yon on the norttu Spring valley along the eastern and southeastern
side, the Sp.ing Valley road on the south and the Roaring Fork River on the west and southwest'
The gently-rolling top ofthe mesq which riop., to the southwest, makes up about two-thirds of the
property, with the remainder consisting oi l"dg"., ?_Iift, and steep slopes that drop away to the
Roaring Fork River. The mesa top is coiered wiih soils and other unconsolidated materials that are
generally thin, varying from two to rarely more than ten feet in thickness. Bedrock is well-exposed
only along the stee"p southwestern slopes of the property, and much more poorll' along the
northeastern slopes ubou" Spri.,g Valley, offthe property to the northeast'
Rocks in the vicinity of the property vary from Precambrianr granites? and gneisses3 up to two billion
years old, exposed in Glenwood Canyon to the basalt4 flows of Miocene age (from about 10'0 to 7'7
miilion years old) that form the uppermost ledges along the southwest side and floor the mesa top of
the property. The entire Paleozoic sequence * A**"titalty exposed in Glenwood Canyon only a few

(Archean" approximately +.600 to 2,500 million years ago (mya); Proterozoic, 2,500 to 570 mya): Paleozoic' 570 to 245 mya:
Mesozoic 245 to 66.4myu and cenozoic. 66.4 mya to th-e pro"nt. A copy of the geologic time scale is anached to this report'
: Granite and ..granitic" rocks (most commonly quartz monzonite or granodiorite) are intrusive igneous rocks
containingmore than loploquarE(puresilica) and where potassiumfeldspar exceeds l0% of total feldspar (granite more than
67 Y'o. quartzmonzonite 33Vo to 670/o, ganodiorite I 0% to 33o/o)'
Igneous rocks are those thaisolidified from molter or partly molten material, i.e. fiom a magma' Igneous rocks
constitute one of the three main classes into which rocks are divided, the others being metamorphic and sedimentary'
lngtsive igreou, rocks are those that consolidated from magma (molten rock) beneath the surface: especially' those
that were forced into or between other rocks.
Feldspars are the most common of the basic rock-forming minerals, and consist of aluminum silicate with varying
arnounts of potassium (orthoclase, microcline) or sodium and calcium (plagioclase goup)'
r Gneiss is coarse.grained high-grad e metamorphrc rock in which granular minerals such as quartz and feldspar
alternate with bands containing finer-grained minerals such as micas (hydraied potassium aluminum silicate with varying
amounts of other elemeils), homblende and other amphiboles, and pyroxenes (amphiboles and pyroxenes are mostly dark
aluminum silicates containing varying amounts of iron, calcium, sodium, and magnesium).
Maamorphic rocks io *nroliauted rocks which have beerr altered in composition, texturc' or internal structurc' or
various combinations thereofi, by pressure, heat, or new chemical substances, usualiy all three and resulting from inoeasing
depth of burial, proximity to intnrsions of molter rock, or migration of mineralized solutions, and again most commonly
combinations of these agents.

unnamed basalt lavars flows interbedded with alluvial gravels and other sediments which are not
commoll. Rocks exposed on and in the immediate zubsurface beneath the Los Amigos Ranch consist
oflimited exposures of the Eagle Valley Formation and Eagle Valley Evaporite along the southern-
southwestern boundary; the Maroon Formation, which forms the red cliffs above the Roaring Fork
along the western-northwestern boundary; and the unnamed basahs, which form capping ledges along
the southwest-northwest boundary and forms the bedrock beneath the soils of the rest of the ranch
The upper Eagle Valley Formation and its equivalents, the Eagle Valley Evaporite and the lower
Maroon Formation all intertongue in complex fashion around the edges of the Eagle basrr, and are
therefore equivalent in age.
Many varieties of semi- to unconsolidated surlace materials of Pleistocene (100,000 to 2 million years
old) and Holocene (present to 100.000 years) age are present inthe area. These include stream
channel flood-plain terrace. debris-flow. and sheet-wash deposits, or alluviurn, depositecl by flowing
waterl talus, landslide and other colluviurq materials deposited primarily by gravity: lacustrine (lake)
deposits in the Spring Valley area immediately northeast of the property; and eolian (wind) deposits
that formthe basis for much of the soil of the upland areas. On the Los Amigos Ranch Quaternary
deposits are limited to sheetwash. colluvium ranging in age from early Pleistocene to recent, talus,
mixed alluvium and colluviurn and loess (fine-grained wind-blown material. mostly silt).
Detailed descriptions of all the units, bedrock and unconsolidated surficial deposits, are presented in
the pamphlets that accompany the four recent geologic maps by Kirkham and others (1995a, 1995b,
1996. 1997) that include the Los Amigos Ranch area. Somewhat abbreviated versions of these
descriptions are included in Mr. Kaufinan's report dated April 10, 1998. In attempting to shorten the
descriptions. certain words or phrases, sentences, and even whole paragraphs were omitted and in
other cases sentences combined. resulting in subtle changes in meaning in some instances; for this
reason I strongly recommend the original sources, as I do for my own definitions of technical terms.

r5 Fluid rock that has poured out onto the earth's surftce. most commonly from a volcano.
'u Most sedimentary rocks and extrusive volcanic rocks were originally deposited horizontally or nearly so, usually
in "beds" that are bottnded by oolor changes. mineralogical changes, surfaces of erosion and nondeposition. and so on. Bedding
planes are formed when the rocks break along such changes. Bedding attirude refers to the strike and dip of beds which ari
not hmizontal, either because they were deposited that way (sand dunes or lava ftlls for example) or more frequently because
they have been tilted by the forces of mountain building. Attitude is most easily daermined on bedding planc;. Strike is the
bearing ofa hqizqrtal line on the bedding plane and is perpendicular to the dip; dip is the angle of departure 6om horizontal
of the bedding plane and is perpendicular to the strike.
'' All rocks exposed at and near the surfrce are fractured to some degree. Fracturing is caused by many agents,
including oling drying the weight of overlying materials during burial. and mountain-building forces. Fractures that occur
in moreor-less repeatable panerns are joints. Fractures where one side has moved relative to the other are.faults.

Formation and the lava flows. as well as recharge area,20 hydraulic head,2r and other hydrologic
controls. Two very important related factors in determining the dhection of groundwater flow in the
Los Amigos Ranch area that have not been sufficiently addressed in previous work that has been
reviewed by the writer are the nature of the pre-lava flow surface of the Maroon Formation and the
overall dip ofthe flows themselves. Unfortunately little is known concerning either of these factors,
and evidence that can be derived from the Kirkham maps is somewhat ambiguous. Elevations of
dated lava flows in Glenwood Canyon suggest that the Colorado River had cut a canyon 200 to 300
feet deep 7.7 million years ago but cut only an additional 300 to 400 feet over the next 4.4 million
years (Kirktnrn, personal communication), so a young stream in roughly the same location would not
be surprising, nor would be the presence of an ancestral Roaring Fork, prior to the first llows dated
at9.& million years. Therefore a low-relief surface on the Maroon dipping from I " to 5' generally
northwesterly is proposed. In additioru the overlying lavas appear to dip as a sequence gently in a
generally westerly direction from source areas thought to be in the Basalt Mountain area (Kirkharn,
personal communication; as of this date Mr. Kirkham wishes to emphasize that a Basalt Mountain
area origin for any ofthe flows in the Spring Valley area has not lcruen established with any degree of
certainty). and it is normal for lava flows, which frequently have highly contorted internal structure.
to dip as a sequence in the direction of the surface over which the original flow spread.
Along the southwest-center part ofthe property, from above the Highway 82 - Spring Valley Road
intersection northwestward for about 1.25 miles. Kirkham and others map a deposit of alluvial gravel
between the lower and upper lava flow sequences. These gravels were apparently deposited by an
ancestral Roaring Fork River, again indicating a general westerly-dipping surface for the Maroon in
the area toward this strearn The connection to the current Roaring Fork drainage area Ls supported
by the presence in the gravels of rocks derived from features unique to the Elk and West Elk
Mo untains (Kirkharn, perso nal c o mmunicat io n).
A gentle westerly dip is fllther suggested by the distnlbution ofthe flows in the ridge between the cliff
outcrops on the west side and the less-well-defined ledges to the east of the Los Amigos Ranch. The
clifftop, which has been dated as belonging to the uppermost (youngest) flow (Kirkhanr, personal
communication), occurs at approximately 6.800 feet, while the mapped basalt bedrock coincident
with the top boulder ledge on the east side varies from 7,000 to 7,200 ft, producing an apparent
westerly dip of less than I o to 3' depending on location, decreasing from southeast to northwest.
Finally, the flows are described by Kirkham and others (1995a 1995b, 1996, 1997) as being a
maximum of 300 feet thick but usually much thinner. The flow-gravel interval on the southwest rim
ofthe mesa is approximately 350 to 400 ft thick suggesting that the entire sequence is present. Drill
hole logs for three holes on the plateau but jus north of the property at elevations ranging from 6,960
ft to 7,020 ft indicate basalt thicknesses of 160 ft to 180 ft, suggesting either thinning or slight
steepening in the dip in this area; it should be mentioned that the sequence does thin rapidly to the
east to the extent of the thickness ofthe gravel beds described above, which Kirkham has advised do
not occur elsewhere in the area (personal communication).

To summarize, the Maroon Formation, which internally dips northeastward in the area of interest at
from 20" to 60" as the result of an essentially-unknown combination of Laramide tectonic activity
and later salt diapiricz2 movement, was eroied to a surface of low relief that dipped gently in.a
genera\, westerty direction toward an ancestral Roaring Fork River prior to the initiation of volcanic
activity which spread basaltic lavas over the region in the lati Miocene. The flows contain
uncorunon interbedded volcanic-related sediments that reflect the topography of the flows upon
which they were deposited. A single alluvial gravel deposit between the two major flow sequences
in the southeastern part of the property lends-support to the concept of an ancestral Roaring Fork
River and the development of a pediment-like23 surface on the Maroon Formation east of the stream
Except where intemrpted by more recent struchral activities the orientation of the Maroon Formation
surface and the ,pi., and lower (and some internal) boundaries of the lava sequence remain
essentially the same today, that is dipping gently in a generally westerly to northwesterly'direction'
The effect of the structure mapped as ttie-Glenwood Springs syncline2a by Kirkham and others on
these surfaces is not known. Kirkham has advised that although he did extend identification of the
structure south into the Los Amigos Ranch on the rnaps, it can be clearly defined in the field only as
far south as Red Canyon, about a mile north of the ranch boundary'
While the local effects of salt diapirism in the Roaring Fork Valley area have been known for some
time. new interpretations by Kirkham and Widmann (lgg7) suggest that the current geological
structure and to a large extent surface topography of the entire Glenwood Springs - Carbondale
region are governed to at least some e>rtent by movement and dissolution of thick intervals of gypsum
and halite in the Eagle valley Evaporite, which underlies vinually the entire area. Of particular
interest are collapse structures that vary from (apparently) only a few tens of feet in maximum
dimersion to several miles. Kirkham and others nup one such structure along the southwest side of
the properry, between the main upper basalt ledge and the top of the Maroon cliffs to the southwest'
and another on the wesr side of Spring Valley about a half-mile northeast of the property. Spring
valley itself, a certainly-anomalous structure, is likely the result of a larger collapse- I'he lapRed
stmctures trend generally northwest - southeast, parallel to the Roaring Fork Valley' itself at least
partially such a structure; Spring Valley paralleis this trend. The collapse structures influence
groundwarer flows in several;uyt, Uut principally by providing local sinks and by superimposing a
fracture (oint) system of varying e>rteniat least internally on any regional fracture system that-ma-v
be present. Fracture rnapping on the Los Amigos Ranch and immediately adjacent areas is difficult

fractures were spaced from about 2 feet to l0 feet or more, are open at the edge of the cliffs but
appear to close in the direction of rock undisturbed by edge effects (virtually none of the observed
rock can be said to have been free of edge effects), and are near-vertical. A third set of minor
fractures. only a few of which were observed, are tighter and have a direction of N 60' to 70" E.
Curiously no significant fracturing parallel to the axes of the mapped collapse structures was found.
even directly adjacent to one of the features, where the N 80' E group was dominant. There is no
indication of columnar jointing,25 and Kirkham advises it is very rare in the region; the closest
observed columnar jointing is in a flow exposed in the roadcut on the hill between El Jebel and
Missouri Heights, several miles southeast of the property (personal communication). T'he fracture
pattern in the undertying Maroon Formation is unknowrU but is assumed to be similar (joint sets with
similar bearings occur in pre-Miocene rocks throughout the Piceance basin immediately to the west
and in fact throughout most of western Colorado and adjacent areas).
Some idea of the nature of the basalt cap can be had from the drilling that has occurred in the area.
According to Wayne Shehon of Shehon Drilling, who with his father has been drilling in the area for
over 40 years and who drilled the three holes closest to the property on the cap, virtually all holes on
the south side of Spring Creek above the lake sediments have produced little or no water. Drilling
conditions have been generally good, with only occasional lost-circulation26 or similar problems. The
basalt flows are solid and drill easily, and the occasional sediment interbeds, which he described
mostty as tufi27 posed no unusual problems either. He described the Maroon as very hard. One hole
was originally drilled to 500 ft. reentered the next year and extended to 800 feet. Mr. Shelton stated
that the hole was reentered without difficulty (no hole collapse, debris at the bottom, etc.), and that
it was completely dry.
The primary recharge area for groundwater in the Spring Valley regron, including the plateau between
Sprrng Valley and the Roaring Fork fuver, is the highlands to the east. Drilling information on and
along the east side ofthe plateau indicates that there is no significant "mound" of water on the west
side of Spring Valley. The almost total lack of springs along the down-dip contact between the lava
flows and the underlying Maroon, from within the flows including the alluvial gravel described above.
or the Maroon Formation above the Roaring Fork River suggests the absence of perched water or
tr More or less parallel, prismatic columns, almost always hexagonal in cross section, that occur occasionally in
basaltic flor,vs and dher ootsive and intnrsive rrcks. It is formed as the result of contraction during cooling, and is dependant
on cooling ratg thiclmess oftlre igrreors body. nature of the contacts ofthe body with other rocks, and chemistrl'of the cooling

5 In rmry drilling air or water, with or without a variety of additives such as fem or mud. is forced down the drill
pipe, through the bit, and back up the hole. The primary purpose is to cool the drill bit, although the fluid also acts as a
lubricant for the bit and rotating drill pipe. The fluid also carries rock fragments (cutlings) to the surface, where samples of
the rock being drilled can be taken. "[,ost circulation" (LC) refers to situations whete return of the fluid and cunings to the
surface stops. The most cornmon causes of [,C include drilling through extremely porous beds, rock with abundant open
fracnms, o oristing voids created by solution. Washing (or blowing) out of extremely soft, unconsolidated, or soluble rocks
by the drilling fluid can also result in LC. LC can be serious, especially where the fluid is lost but the cuttings remain in the
hole wh€re thcy can plug the bit and bum it offor bind the drill pipe. On the other han4 thousands of feet of hole have been

any signfficant water flow above the principal water tlble2s that connects the Sp.ing valley aquifele
with the Roaring Foik zuuer. Flow from the aquifer to the river is controlled by the two major
subvertical fracture systems. Ng0E and N10w, in the basalts and the underlying Maroon Formation'
the gentl,v-westerlv- to northwesterly-dipping flow sequence boundaries and the pre-flow Maroon
surface. and more-steeply dipping beddid pi*., in the Maroon, which strike northwesterly, all of
which suggest a generally westerly to so-uthwesterly flow of groundwater under the Los Amigos
Ranch.
Considering all of the above, I concur with the conclusions of Resource Engineering Inc', as
augmented by Robert Brogdan of Bishop-Brogdan Associates, Inc., in his letter report dated April
23.lggg.wherein it is coicluded that gior.rna*ater in the Los Amigos Ranch area is deep and that
flow is southwesterty torn the highlandJ east of Spring valley toward the Roaring Fork River' The
general geology of the area suggesrs that leach field efluent will migrate essentially vertically through
fractures in first the basalt cap of the mesa and then through the Maroon Fo.rmation to the water
table. where it will join the general flow toward the Roaring Fork River. Such diversion from vertical
movement as may occgr *ill by govemed by the gentle westerly dip of the lava bed sequence and the
pre-flow erosional surface on the Maroon and the northwest strike of the northeasterly-dipping beds
of the Maroon Formation all of which will tend to direct the water in a westerly to northerly direction
away from the water supply wells to the east of the property'
