Water Quality Summary 2019

Lewis & Clark’s water originates from wells that tap into the Missouri: Elk Point Aquifer adjacent to the Missouri River.  A total of 5.7 billion gallons was delivered to the members in 2018 for a daily average of 15.6 million gallons.  The treated water is very high quality.  Lewis & Clark does extensive testing for contaminants in the water and only the few items listed on the Table of Detected Contaminants were found to be present in reportable quantities.  The level of these contaminants is less than what would be considered harmful.
