Background and Major Changes

All community (COM) and non-transient non-community (NTNC) public water systems in Massachusetts required to comply with the Lead and Copper Rule (LCR) will be required to comply with the Lead and Copper Rule Revisions (LCRR) starting October 16, 2024.

On December 16, 2021, the U.S. Environmental Protection Agency (EPA) announced final revisions to the National Primary Drinking Water Regulations for lead and copper under authority of the Safe Drinking Water Act - called the Lead and Cooper Rule Revisions (LCRR). The LCRR will identify the most at-risk communities and ensure systems have plans in place to rapidly respond by taking actions to reduce elevated levels of lead in drinking water. Some of the major changes include:

Requiring COM and NTNC systems to inventory (identify) and make public the locations of lead service lines (LSLs) and to develop an LSL replacement plan by October 16, 2024 (note that the requirements take effect on the first day of implementation).
In addition to the system-wide 90th percentile action level of 15 parts per billion (ppb), the LCRR also establishes a 90th percentile system-wide trigger level of 10 ppb of lead to assist systems to plan to further address lead in drinking water.
Requiring COM systems to offer testing to all schools and childcare facilities served.

See more information on the LCRR from EPA.

EPA also announced that future additional updates to the LCRR will be made to further evaluate if they protect families and communities, particularly those that have been disproportionately impacted by lead in drinking water. These future updates are called the Lead and Copper Rule Improvements (LCRI), and EPA intends to promulgate them prior to October 16, 2024. See more information on the LCRI at EPA.

Information for Massachusetts Consumers

Massachusetts Consumers can learn more about the LCRR and it's requirements, such as the Service Line Inventory and how consumers will be notified if served by a service line that contains or may contain lead by visiting the MassDEP Consumer's Frequently Asked Questions about the LCRR Service Line Inventory Webpage.

MassDEP has created an interactive map with Public Water System's Service Line Inventory (SLI) Submissions for public viewing. SLIs will be available as they are reviewed by MassDEP. For questions on your Public Water System SLI, this Map also contains the contact person for your system. The Massachusetts Service Line Inventory is available here: Massachusetts Service Line Inventories Hub Site

For summary statistics of how many Non Lead, Unknown, Galvanized Requiring Replacement (GRR) and Lead service lines, see the Service Line Inventory Summary Sheet.

LCRR Service Line Inventory and Replacement Plan Templates

You can find templates and instructions for the development of LCRR Service Line Inventories and Replacement Plans on the Lead & Copper Forms & Templates webpage. The compliance date for the Service Line Inventory is October 16, 2024.

NOTE: All public water systems, even those without lead service lines, are required to submit an initial FULL service line inventory by October 16, 2024. MassDEP Drinking Water Program is encouraging PWS to submit their draft inventories by April 1, 2024. This would give public water suppliers time to make sure their inventories are complete and to receive any technical assistance, if needed, to ensure compliance on or before the regulatory deadline.

MassDEP LCRR Tools & Toolkits for Service Line Inventory Work

MA Lead Service Line Identification (MA-LSLI) Web App

MassDEP developed a "crowdsourcing application" (hereafter referred to as "the App") to assist both consumers and PWS to identify lead service lines. The App is a web-based tool for consumers to assist in the identification of lead service lines. No downloading of software is required. The App is a collection of Smartsheet forms, sheets, and workflow automations that allow your customers to submit photos of their service line for identification purposes. This can be helpful for PWS in compiling their line inventories and in prioritizing lead service line replacements. See Instructions for Using the App.

LCRR Service Line Inventory Public Outreach Toolkit

Under the Lead and Copper Rule Revisions (LCRR), all community and non-transient non-community systems are required to submit a service line inventory by October 16, 2024. To help these systems develop their inventories and encourage community involvement, the MassDEP Drinking Water Program developed this outreach toolkit that contains posters, infographics, social media images and other tools.

Customer Infographics

LCRR Service Line Inventory Press and Media Toolkit

This Toolkit is a compilation of materials that can be shared digitally (social media), physically (flyers) and through broadcasting (a slide deck) to your community, to interest your community into helping local public water suppliers to identify service lines in their service area.

Funding Opportunities for PWS to Address Lead

Service Lines Inventory and Replacement Plan Grant Program

MassDEP is accepting Lead Service Lines planning grant applications, on a rolling basis, while funding is available.

Eligible activities for these planning programs include:

Service Line Inventory - Completing a comprehensive Service Line Inventory for both public and private portions that will be made publicly available. This comprehensive inventory project could include activities such as inspecting physical service lines, compiling paper records, initiating a consumer lead service line identification program, but must include submitting the complete inventory to MassDEP in a digital format specified by MassDEP or in an alternate format approved by MassDEP that can be readily compiled into the MassDEP data system.
Lead Service Line Replacement Program - Preparing a Lead Service Line replacement program for the PWS that complies with the LCRR. PWS’ lead service line replacement plans need to incorporate the MassDEP public health protection goal by planning to replace all lead service lines in 5 years or as soon as possible.
Use of the MassDEP-provided tools will ensure the submission of a service line inventory and lead service line replacement program summary in a digital form acceptable to MassDEP.

Assistance for Small Community Water Systems and Non-Transient Non-Community Systems - Lead Service Line Planning Program

This program is available for PWS serving a population of less than 10,000. MassDEP will use the $1.3 million of the set-asides from the DWSRF Lead Service Line Grant to contract with a qualified technical assistance provider to complete eligible planning projects working with the PWS.

Small PWS must notify MassDEP of their interest in this technical assistance and provide an update on how they are preparing for the LCRR requirements by submitting the MassDEP Service Line Inventory and Lead Service Line Replacement Plan Technical Assistance Survey. PWS will be contacted, and technical assistance will be provided virtually or in person, depending on need and resources.

Massachusetts Free Water-Smart Pilot Program for Public Water Systems

Beginning in November 2027, all community water systems will have to offer lead testing to at least 20% of the elementary schools and 20% of the childcare facilities in their service area, except for those schools and childcare facilities that were either constructed or had full plumbing replacement on or after January 1, 2014 and are not served by a lead service line, galvanized requiring replacement service line, or service line of unknown material. PWS must ensure that all facilities are initially offered testing within 5 years. To assist PWS and to support lead in school testing, MassDEP launched a FREE testing pilot program for PWS to test schools and childcare facilities ahead of these federal requirements. This pilot program includes: Facility mapping Laboratory testing Technical assistance Notification and results dissemination For more information about this Pilot Program please contact program.director-dwp@mass.gov. Subject: Water-Smart Pilot Program for PWS.

LCRI Waiver for Lead Testing in Schools and Childcare Facilities

Starting in November 2027, PWS may receive a full or partial written waiver from MassDEP to exempt them from the school and childcare facility sampling requirements of the LCRI if they participate in the Pilot Program, or have a lead in schools and childcare facilities sampling program that meets the LCRI waiver requirements. To be considered for a waiver, complete and submit the Lead Testing Waiver Application for Schools and Childcare Facilities.
