Lead can enter drinking water from lead pipes or lead-based solder on water pipes. This can occur when pipes containing lead corrode, especially where the water is acidic or has low mineral content. The federal Lead and Copper Rule requires a public water system to test tap water from sites likely to have plumbing containing lead. If more than 10 percent of tap water tested exceed the lead action level of 0.015 milligrams per liter, then a public water system is required to notify residents and take steps to reduce lead levels in the public drinking water supply.

Lead can also leach into water inside the home from corroding brass or chrome-plated brass faucets and fixtures with lead solder, particularly when running hot water. Even if you get your water from a private well, there may still be a concern about lead in your water if the plumbing in your home contains lead solder or lead materials. Homes built before 1986 are more likely to have lead pipes, fixtures and solder. Homes built after 1986 have “lead-free” plumbing, but still can contain trace amounts of lead that can dissolve in water. You may reduce lead in your water by only using cold water taps for drinking and food preparation and running water for at least 30 seconds or until the water is cold before use (see Steps to Reduce Lead in Drinking Water below).

New York State Law and regulations require all public school districts and Boards of Cooperative Educational Services to test drinking water for lead contamination and to take responsive actions to remove sources of lead. Schools must also notify staff, parents and guardians of students in writing when outlets exceed the action level indicating contamination and maintain test results on their websites.

Bottled water suppliers must routinely test their water supply for lead. The U.S. Food and Drug Administration has established a maximum contaminant level of 0.005 mg/L for lead in bottled drinking water.

How to Find Out If You Have a Lead Service Line

How to Test Your Household Water

Certified commercial laboratories can test for lead in drinking water. The cost ranges from $15 to $50 per sample.

Take Steps to Reduce Lead in Household Drinking Water

  • Run water for at least 30 seconds if it hasn't been used in several hours to flush out lead or until water is cold before using it for drinking or cooking.
  • Use only cold tap water for cooking, drinking or making a baby's formula; lead dissolves more easily into hot water. Avoid cooking with or drinking hot tap water; DO NOT USE HOT TAP WATER TO MAKE BABY FORMULA.
  • Do not boil water to remove lead. Boiling water will not reduce lead.
  • Replace plumbing fixtures if they are found to contain lead with Lead Content Certified Products.
  • Use bottled water that is certified by New York State or a Lead Content Certified water filter if your home is served by a lead service line, or if lead-containing plumbing materials are found in your home. Follow the manufacturer’s instructions to maintain and replace all water filters.

Funding Opportunities to Eligible Public Water Systems

New York State provides grant funds to some municipalities for the replacement of lead water service lines from the public water main to the residence as part of New York State's Lead Service Line Replacement Program. The Drinking Water State Revolving Fund (DWSRF) and Water Infrastructure Improvement Act (WIIA) also can provide municipalities with financial assistance for the replacement of lead service lines.
