CHESTERFIELD COUNTY, Va. (WRIC) -- Chesterfield County announced on Tuesday that its water service lines are lead-free after a multi-year inventory effort. Chesterfield County has completed a service line inventory that shows pipe material used in its water distribution system is free of lead. Both the publicly owned (from the water main to the meter) and privately owned (from the meter to the building) portions of the service lines are included. The county submitted the inventory once the process was complete, and the Virginia Department of Health approved it on Oct. 22. There were several actions taken to complete the inventory process, including but not limited to field investigations, statistical analysis models and reviewing historical records. Public water systems were required by the Environmental Protection Agency's Lead and Copper Rule Revision (LCRR) to complete a service line inventory by Oct. 16 of this year. There will be new and more stringent lead regulation -- the Lead and Copper Rule Improvements -- enforced upon public water systems by the EPA in three years, which will build on the LCRR and service line inventory, according to the county. For more information about the service line inventory, including the results, an interactive map for customers to use, and the steps taken to certify the lead-free status, view the county's webpage.
