Water Quality

General Information

The Jeffco Environmental Services Department operates seven water treatment plants and two wastewater treatment plants to support schools and District facilities in mountain areas not supported by a municipal utility. Water systems operate under the regulations set by the EPA Safe Drinking Water Act and the Colorado State Health Department. Throughout the year comprehensive sampling and monitoring occur, documenting the water system's compliance with all state and federal requirements and regulations.

Sites Serviced

Environmental Services provides treated water for the following Jeffco locations:

  • Conifer Senior High School
  • West Jefferson Elementary School
  • West Jefferson Middle School
  • Marshdale Elementary School
  • Elk Creek Elementary School
  • Coal Creek Elementary School
  • Windy Peak OELS
  • Mt. Evans OELS

Water is supplied by Jeffco at these sites from water wells or reservoirs at or near these locations. Water is filtered and treated prior to delivery (including chlorination - a requirement for any water supplier). Jeffco conducts routine sampling of treated water both at the point of treatment and at several points throughout the distribution system to confirm water quality is maintained. Sampling results are available from Environmental Services upon request.
