Lead Service Line Solutions
Starting in 2021, the Environmental Protection Agency (EPA) announced revisions to the 1990 Lead and Copper Rule (LCR), including the Lead and Copper Rule Revisions (LCRR) and Proposed Lead and Copper Rule Improvements (LCRI). These critical updates aim to enhance public health protection by addressing lead and copper levels in drinking water systems. The proposed LCRI changes introduce several significant alterations and deadlines to the LCRR that water suppliers must be aware of to ensure compliance.
