Dear Sir or Madam: Please find the attached data summary table and laboratory analysis report for water samples collected from the Hunter 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 comments. Sincerely, EnCana Oil & Gas (USA) Inc. Parachute office should you have any questions or Brett Middleton EHS Field Coordinator Attachments Cc: David Grisso, EnCana Oil & Gas (USA) Inc.

The results prompted a few questions: Middle Fork water storage Pond: why are the Dissolved solid readings (550 mg/l) higher than thL Regulatory Standards (500 mg/l) found in. the up graO'lent rionitoring well and is there any way to reduce those levels to below Regulatory Standards? Hunter Mesa Water Treatment Plant: Why are the Manganese readings (0.09 mg/l) higher than the Regulatory Standards (0'05 mg/l) found in the iresh wJter no6ing pond and is there any way to reduce those levels to below Regulatory Standards? Lake Fox Water Storage Pond: The sole purpose of the Board of County Commissioner's requirement for Encana to install a down gradient water monitoring well was to monitor any activity that might come from Lake Fox. We ippreciate the results from the neighboring well; however, what does Encana propose to do to its monitoring well so that it functions as required? We look forward to hearing your response to these questions' I am happy to discuss over the phone as well. Very truly yours, Director, Building & Planning Department 970.94s.8212 108 Eighth Street, Suite 401 ' Glenwood Springs, CO 81601 (970) 945-8212' (970) 285-7972' Fax: (970) 384-3470 1) 2) 3) Fred A.

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.

The percent recovery, expressed as a percentage of the theoretj-cal concentrationr has statistical controf limits indicating that the ana.Iytic process is 'in control"' If a target analyte is outside the controf limits for the laboratory conirol sample or any other control sample, the parameter is flagged with a "J4" qualifier for all effected samples' Matrix Spike and Matrix Splke Duplicate - is two alj-quots of an environmental sample that is spiked with known concentrations of targeE analytes.

Dear Sir or Madam. Please find the attached data summary table and laboratory analysis report for water samples collected from the Hunter Mesa Water Treatment Facility on May 30, 2013. The middle pond was empty at time of sampling 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.

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 o, ur"d 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.
