In 2021, the U.S. EPA updated the Lead and Copper Rule (LCR) to protect communities from lead exposure better. Under these new rules, Roseville and other water systems submitted a service line inventory by October 16, 2024, identifying the materials used in water service lines.
Roseville has completed its initial inventory and found no lead or galvanized service lines requiring replacement (GRR). This conclusion was reached through a thorough review of historical records and inspections.
Using stratified random sampling, the city carefully selected and inspected a representative group of service lines, confirming that all were non-lead. This method ensures that different types of service lines, based on their age or location, are adequately represented in the inspection.
Although no lead was found, Roseville will continue to update the inventory annually and remain vigilant in ensuring the safety and quality of the water supply.
