Lead Service Line Replacement Program If your home was built before 1939, it might have a lead water
service line. Lead water service lines can leach lead and elevate
lead levels in your family’s drinking water. Elevated lead levels
may cause severe health problems, especially for pregnant women,
persons with disabilities, and young children. If your house water
service line is lead, replace it now with a Lead Service Line
Replacement Program (LSLRP) grant funded by the New York State
Department of Health. More Info
For more information about EPA lead service line resources,
including service line inventories, engaging with the community,
