Lead Service Line Inventory

ArcGIS Map Viewer

The Municipal Authority of the Borough of Somerset (MABS) is taking steps to identify the types of service line materials used by each of its customers. The service line is the pipe that connects your home or building to the water main in the street. Service lines may be made of lead, copper, galvanized metal or plastic. 

The U.S. EPA’s Lead and Copper Rule Revision requires us to identify all lead service lines by October 2024. Through our current waterline replacement project, we have begun to identify and replace existing lead service lines within the project’s scope. However, thousands are still unknown and we’re going to need your help to comply with this federal requirement. MABS is committed to providing safe and reliable water to all our consumers. We are updating our records and working towards a lead-free water supply system for our customers. A video with more information, provided by EPA, can be viewed by clicking the following link.


MABS conducts routine testing to ensure that our water meets all state and federal water quality requirements. Lead is not detected in the drinking water when it is being distributed and there is no current concern at large in our system. 

Lead contaminations of drinking water is often the result of corrosion in the plumbing or water service belonging to the water customers. If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. 

Since lead exposure in drinking water typically comes from your plumbing fixtures and not the source of your water supply, it’s important for both public drinking water customers as well as private well water users to follow these tips to reduce your exposure to lead.

  • Run your water to flush out lead and copper for 15-30 seconds or until it becomes cold. 
  • Use cold water for cooking and preparing baby formula. 
  • Do not boil water to remove lead or copper. 
  • Test your water for lead or copper. 
  • Identify if your plumbing fixtures contain lead.

MABS will begin collecting customer side service line inventory. We will be verifying the type of water service line coming from the water main in the street to your home as well as your internal plumbing material. There are several ways you can assist with this process. 

We will begin sending out letters and personnel to start the process of gathering information for our records and to comply with DEP requirments. We are requesting that you let them into your home so that they can gather the necessary information. These employees will have identification badges; additionally, you can call the Borough to confirm the name of an employee. If you have any concerns or questions, don’t hesitate to contact us. 814-443-2661. 

In addition, you have the option to fill out the survey that is provided in the GIS Map with the collected information. In this map you can view the progress and fill out the survey to assist with the customer owned service line records. Please keep in mind that we may still need to request verification by means of our employees coming into your home. View ArcGIS Map  

 Increases in population, and commercial and industrial establishments, have increased the demand for upgraded water and sewer facilities, etc. Our water treatment plant can now produce two million gallons per day, with average daily pumping of 1.5 million gallons.
