How Lead Gets Into Drinking Water

• Lead can enter drinking water when service pipes that contain lead corrode.

• The most common problem is with brass or chrome-plated brass faucets and fixtures with lead solder, from which significant amounts of lead can enter into the water, especially hot water. Homes built before 1986 are more likely to have lead pipes, fixtures and solder.

• The Safe Drinking Water Act (SDWA) has reduced the maximum allowable lead content.

• The SDWA was implemented in 1974 with the most recent amendments, including the Lead and Copper Rule (LCR), implemented in 2015.
