Water is our most valuable shared resource and together we can keep it
that way for generations to come.
Source Water Delineation and Assessment Report

As required by the EPA in 2003, a Source Water Delineation and Assessment report was completed for MWC and submitted to the Department of Environmental Quality and the EPA. Last revised in May 2015, we utilize this report as an opportunity to update our Wellhead Protection Program with the latest information and technologies in modeling and mapping with linked databases. This assessment resulted in an updated list of possible contaminant sources to our aquifer, some of those being underground storage tanks, public and private sumps, leaking pipelines, spills along railroad tracks and highways, sewer lift stations and septic systems. This has resulted in a very useful tool for protection of our valuable drinking water supply.
