In February 2016, U.S. Environmental Protection Agency (EPA), prompted by recent events in Flint, Michigan and other U.S. cities, wrote states about the need to enhance at all levels of government the oversight of implementation and enforcement of drinking water regulations, including the Lead and Copper Rule. In an effort to enhance public transparency and public access to data and compliance information the City will now make the latest Lead and Copper Report available on our website. The results from the City's Lead and Copper sampling continue to meet all State and Federal drinking water standards. Please note, the City has a limited number of lead joints and service lines remaining in the distribution system. Most lead service has been replaced over the years and will continue to be removed during the final phases of the metering program.
Exercises Corrosion Control Methods
In addition, the City exercises corrosion control methods which protect the pipes and decrease the rate of corrosion. Lead found in tap water usually comes from the corrosion of internal household plumbing with older fixtures or from the solder that connects pipes. The latest Lead and Copper Report and additional information can be found below. For further questions please call 209-333-6878.
