RE: High Mesa Water Treatment Facility Water Quality Data.
Dear Sir or Madam:

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 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.
