Lead water service lines remain a significant concern in NYC, particularly in older buildings. The EPA estimates that NYC has tens of thousands of lead service lines still in use. Lead exposure can cause serious health problems, especially in children. NYC DEP has launched a Lead Service Line Replacement Program that offers free replacement for eligible properties. The program prioritizes properties with confirmed lead service lines and those in environmental justice communities. If your property was built before 1960, there is a higher chance your water service line contains lead. Contact NYC DEP or Sewer & Water Pros to have your service line inspected.
