Notification of Known or Potential Service Line Containing Lead

v>EPA FACT SHEET

Under the 2021 Lead and Copper Rule Revisions (LCRR), water systems must provide people with specific
information about their service lines. This requirement begins on October 16, 2024. Since this is a new
regulatory requirement, EPA recommends water systems plan ahead to ensure readiness to comply with the
new requirements. This fact sheet provides an overview of the EPA's requirements for content, delivery, and
timing of this notification.

provide notification of known or potential SL containing lead when applicable.

Health Effects Language: Exposure to lead in drinking water can cause serious health effects in all age groups.
Infants and children can have decreases in IQ and attention span. Lead exposure can lead to new learning and
behavior problems or exacerbate existing learning and behavior problems. The children of women who are
exposed to lead before or during pregnancy can have increased risk of these adverse health effects. Adults can
have increased risks of heart disease, high blood pressure, kidney or nervous system problems.

Notifications must be provided to people served by the water system by the given service line.

HOW DO I PROVIDE A NOTIFICATION OF KNOWN OR POTENTIAL SL CONTAINING LEAD?

You must provide the notification, by mail or by another method approved by the primacy agency. An example
of another method may be a NTNCWS posting the results on a bulletin board in the facility to allow consumers
to review the information.

The timing requirements for initial, repeat, and discontinuing notification of known or potential LSL are as
follows:

Initial: You must provide the initial notification within 30 days of completion of the initial SL inventory. You
