Anne Arundel Water Service Inventory Program

WSIP Background

Lead and Copper Rule Background 

In January 2021, the U.S. Environmental Protection Agency (EPA) released the Lead and Copper Rule Revisions (LCRR), which affects all water utilities in the nation. Anne Arundel County has been monitoring lead and copper in homes in accordance with the 1991 Lead and Copper Rule (LCR) and has not exceeded the regulatory action levels for either lead or copper. The revised regulations include new requirements for water utilities including, for the first time, a service line material inventory, updated sampling and reporting procedures, and additional public outreach.

Anne Arundel County prohibited the use of lead in the construction of water service lines in 1936 and has been actively replacing lead service lines for decades. Testing for lead in accordance with the LCR has been ongoing since 1991. As such, the probability of finding lead in the County water system is low, with our water quality consistently remaining well above state and federal regulatory standards.

About the Water Service Inventory Program

In response to the EPA’s LCRR, Anne Arundel County launched the Water Service Inventory Program (Water SIP), a comprehensive initiative to meet the requirements of the revised regulations. 

A primary objective of the Water SIP is to provide educational outreach for residents to understand the LCRR, its impacts on Anne Arundel County water system customers, and any action needed by the public. This webpage serves as a one-stop destination for all information related to the program, providing easy access to valuable resources and tools. 

A service line is an underground pipe that connects your home to the public water main, delivering water to faucets, bathtubs, showers, and other fixtures.

Current records show that Anne Arundel County does not have any known utility-owned lead service lines in our service areas. Although lead service lines are unlikely since the 1936 ban, we are requesting the public’s assistance to identify service line pipe material in homes where no data currently exists.

Only customers with an unknown service line material are being asked to fill out and submit a self-reporting survey. To determine if your service line is listed as being made from an unknown material, type your address in the interactive map below. If a blue dot appears, you will be prompted to take the survey. If the material of your service line is listed, no further action is needed on your part.  

The information from the survey will be used to create an inventory that will be made available on this site. The inventory is a major component of the LCRR and must be submitted to the EPA by October 2024.

Customers listed as having a service line of unknown material may receive a letter from the County in the mail requesting the completion of the self-reporting survey.
