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.

Questions and answers

Under the EPA’s updated Lead and Copper Rule, Roseville has identified and categorized all public and private water service lines by material type. This inventory, completed by October 16, 2024, helps us understand the condition of our water system and address any issues. We’ll keep updating this inventory by confirming details and identifying unknown materials each year.
The EPA created the Lead and Copper Rule (LCR) in 1991 to control lead and copper in drinking water. Water systems must test for these metals in homes and take action if levels are too high. The rule was updated in 2021 and is now known as the Lead and Copper Rule Revisions (LCRR). It requires a full-service line inventory by October 16, 2024.
Lead pipes were widely used in U.S. cities for drinking water in the early 1900s. Millions remain in use today, posing health risks, as seen in Flint and Newark. By the 1930s, copper replaced lead due to its safety and durability. Galvanized steel was common from the 1940s to the 1960s. In 1986, Congress banned lead pipes in public water systems, but copper is still allowed under the Lead and Copper Rule.
No. City records show Roseville does not have lead service lines. If we find lead during maintenance or sampling, we replace it immediately.

Yes. Roseville meets LCRR requirements by:

1. Running an effective corrosion control program to reduce pipe corrosion.
2. Proactively working with customers to check service lines.
3. Regularly testing water samples for compliance

Lead mainly comes from household plumbing, such as old pipes, brass fixtures, and lead solder. If water sits in these pipes for several hours, lead can dissolve into the water. Lead particles can also attach to galvanized steel and be re-released over time. Regulations like the Lead and Copper Rule help keep these levels low.
First, locate your water meter box, usually near the street—the water meter marks where the service line changes from city-owned to customer-owned.
Yes, Roseville’s drinking water is safe. We test it regularly and follow strict standards set by the EPA. Our water meets or exceeds safety guidelines, including for lead. Water Quality Reports.
There’s no safe level of lead in the human body. Lead exposure can cause serious health problems, especially for children. It can lower IQ, cause behavior issues, and increase the risk of heart disease and high blood pressure in adults. You can learn more on the EPA's website.
Roseville works closely with local and state health agencies to prevent lead exposure. We follow all steps required to reduce lead risks and keep authorities informed.

Although Roseville's current inventory shows no lead service lines, if lead is ever detected, the city will take immediate action. This would include:

  • Notifying affected residents immediately with clear instructions on what to do.
  • Providing alternative water sources if necessary.
  • Replacing any lead service lines as quickly as possible.
  • Additional water testing is conducted to ensure the issue is resolved.
  • Coordinating with local and state health agencies to ensure public safety and compliance with all regulations.
Children are more vulnerable to lead exposure. Over five years, the city will test water at elementary schools and childcare facilities to ensure its safety. The results will be shared with each facility.
The city will contact elementary schools and childcare facilities for testing. Secondary schools can request testing by emailing waterdistributionadmin@roseville.ca.us or calling (916) 774-5750.
The city regularly communicates with school and childcare leadership about testing and safety measures. We provide information about lead health risks and methods to reduce exposure. Notifications are sent by mail, email, or phone to ensure all facilities stay informed.
