Dear Sir or Madam: Please find the attached data summary table and laboratory analysis report for water samples collected from the High Mesa Water Treatment Facility on June 4,2008. The data summary table also lists several reference standards for comparison with the analytical results. These standards are provided for relative comparison only, as the water is not intended to comply with any of the referenced regulatory standards. The water will be contained on site or used solely for natural gas exploration and production activities. As such, the water will not come in contact with the general public or with environmental receptors such as soil, ground water, or surface water. Please do not hesitate to contact our Parachute office should you have any questions or comments. Sincerely, EnCana Oil & Gas (USA) Inc.

The detection limlt is elevated in order to reflect the necessary dilution. (ESc) - Additiona.l- method/sampl-e j-nformation: Sample(s) received past/too close to holding time expiration. Qua]-ifier Report Information ESC utilizes sample and result qual-ifiers as set forth by the EPA Contract Laboratory Program and as required by most certifying bodies incfuding NELAC. In addition to the EPA qualifiers adopted by ESC, we hawe implemented ESC qualifiers to provide more information pertaining to our analytical results. Each qualifier is desj-gnated in the qualifier explanation as either EPA or ESC. Data qualifi,ers are intended to provide the ESC client with more detailed information concerning the potential bj-as of reported data. Because of the wide range of constituents and variety of matrices incorporated by most EPA methods,it is comon for some compounds to fal-1 outside of established ranges. These exceptions are eva]-uated and all reported data is valid and useable unless qualified as 'R' (Rejected). Def .initions Accuracy - The relationship of the observed value of a known sample to the true va.lue of a known sample. Represented by percent recovery and relevant to samp],es such as: contro]- sampl-es, matrix spike recoveries, surrogate recoveries, etc. Precision - The agreement between a set of samples or between duplicate samples. Relates to how close together the results are and is represented by Re.l"ative Percent Dif ferrence. Surrogate - Organic compounds that are sj-milar in chemical composition, extraction, and chromotography to analytes of interest. The surrogates are used to determine the probable response of the group of analytes that are chem- ically related to the surrogate compound. Surrogates are added to the sample and carried through all- stages of preparation and analyses. TIC - Tentatively Identified Compound: Compounds detected in samples that are not target compounds, internal standards, system monitoring compounds, or surrogates.
