June 26, 2007 Garfield County Building & Planning Department 108 8th Street, Suite 201 Glenwood Springs, CO 81601 RE: High Mesa Water Treatment Facility Water Quality Data. Dear Sir or Madam: 2717 County Road 215 Suite 100 Parachute, CO 81635 P: (970)285 -2739 Please find the attached data summary table and laboratory analysis report for water samples collected from the High Mesa Water Treatment Facility on May 8, 2007. 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.
