Dear Sir or Madam: 143 Diamond Avenue Parachute, CO 81635 1': (970)285-2739 �{r EA s° JUL U 7 2014 GARFIELD courg Afmurviry DEVELOP?: EN T Please find the attached data summary table and laboratory analysis report for water samples collected from the Lake Fox Water Storage Pond on June 12, 2014. The on-site Monitoring Well was dry on the date that Lake Fox was sampled. 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 contained in Lake Fox is from a fresh water source. Please do not hesitate to contact our Parachute office should you have any questions or comments. Sincerely, Encana O_-.

TB (ESC) - Additional method/sample information: Sample(s) received past/too close to holding time expiration. Qualifier Report Information ESC utilizes sample and result qualifiers as set forth by the EPA Contract Laboratory Program and as required by most certifying bodies including NELAC. In addition to the EPA qualifiers adopted by ESC, we have implemented ESC qualifiers to provide more information pertaining to our analytical results. Each qualifier is designated in the qualifier explanation as either EPA or ESC. Data qualifiers are intended to provide the ESC client with more detailed information concerning the potential bias of reported data. Because of the wide range of constituents and variety of matrices incorporated by most EPA methods,it is common for some compounds to fall outside of established ranges. These exceptions are evaluated and all reported data is valid and useable "unless qualified as 'R' (Rejected)." Definitions Accuracy - The relationship of the observed value of a known sample to the true value of a known sample. Represented by percent recovery and relevant to samples such as: control samples, 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 Relative Percent Differrence. Surrogate - Organic compounds that are similar in chemical composition, extraction, and chromatography 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.
