Lead can enter drinking water when service pipes or plumbing inside a home contain lead corrode, or break down. Lead from these pipes, faucets, or fixtures can get into the water, especially hot water.
A small number of homes in Benton Harbor were found to have lead levels above the action level. An action level (water lead content > 15 ppb) is the amount of lead that requires an action to reduce lead in drinking water. More testing is underway to learn where the lead is coming from.
