In an effort to eliminate lead in drinking water, the Environmental Protection Agency has mandated that all water systems complete an inventory of all customers’ service lines. Exposure to lead is a health hazard and can particularly affect infants and children. Since lead can enter drinking water through lead pipes and plumbing fixtures, the ultimate goal of this initiative is elimination of all lead service lines.

Do You Have a Lead Service Line?  Test to find out.

Materials needed: A strong magnet, a coin and a flathead screwdriver.


1. Find the water service line entering the building:
The water service line will typically enter the building through the basement floor or the basement side wall. If you don’t have a basement, the service line will likely enter the building through the floor on the main level. A shut-off valve and water meter will be installed on this pipe. Test the pipe between the entry point into the building and the shut off valve, as shown at right.


2. Scratch test:
Scratch the outer surface of the pipe with a coin or flathead screwdriver. Take caution to not puncture a hole in the pipe. Do not use sharp objects for this test.


3. Magnet Test:
Place a magnet on the pipe to check if it sticks to the pipe.
