Situated very near the top of the Blue River Watershed, the Metro District and its customers benefit from a virtually pristine water supply. Potential upstream sources of contamination are comparatively few and ours is an entirely groundwater-based system. The drinking water at Copper Mountain comes from three wells located within the West Ten Mile Creek alluvium. Our source water quality is exceptional and fully compliant with Primary Drinking Water Standards promulgated by the Environmental Protection Agency and enforced locally by the Colorado Department of Public Health and Environment. Because of the exceptional quality of the source water, the only treatment process that the Metro District employs is limited chemical disinfection, prior to delivering the water to our customers. Please visit the Water Quality Reports section of our website for more information on water quality and supply.
