Water Quality

The Left Hand Water District is proud of the high-quality water we provide daily to our customers. Our treatment plant operators are educated, trained and motivated to optimize treatment plant performance for water quality. All public water suppliers are required to meet stringent water quality criteria set forth by the US Environmental Protection Agency (EPA) as well as the Colorado Department of Public Health and Environment (CDPHE). Our water consistently meets or exceeds these standards.

Source Water Protection

The Left Hand Water District is committed to protecting the quality of our source waters. We worked with the CDPHE to develop a Source Water Protection Plan (SWPP) to delineate the area to be protected, identify potential sources of contamination in the area, implement measures to manage these potential sources and plan for the future.

We also partner with the Watershed Center and the St. Vrain and Left Hand Water Conservancy District in the effort to protect our source water and encourage improved water management.
