Water Quality

Delta County Environmental Health program partners with private and local, state, and federal entities to maintain and improve water quantity and quality in the County.  The Delta Board of County Commissioners is dedicated to preserving the quality and quantity of the water resources of Delta County and has therefore entered into a long-term research project to study the hydrology and science of water in the County.

If you are interested in learning more about getting a permit for a new well, contact the Colorado Division of Water Resources.  New wells, and those in submitting subdivision applications, will need to submit water sample reports to the Health Department.
