Question: EPA is initiating the Drinking Water Lead Reduction Plan to strengthen, update and clarify existing requirements for water utilities and states to test for and reduce lead in drinking water.Any information?
Answer: Drinking water does not start out containing lead. Lead is picked up as water passes through pipes and household plumbing fittings and fixtures that contain lead. Water leaches lead from these sources and becomes contaminated. In 1991, to reduce lead in drinking water, EPA issued the LCR. The LCR requires water utilities to reduce lead contamination by controlling the corrosiveness of water and, as needed, replace lead service lines used to carry water from the street to the home. Under the LCR, if 10 percent of required sampling show lead levels above a 15 parts per billion (ppb) action level, the utility must 1) take a number of actions to control corrosion and 2) carry out public education to inform consumers of actions they can take to reduce their exposure to lead. If lead levels continue to be elevated after anti-corrosion treatment is installed, the utility must replace lead service lines. Because virtually all lead enters water after it leaves the main system to enter individual homes and buildings, the LCR is the only drinking water regulation that requires utilities to test water at the tap. This also means that individual homes will have different levels of lead in their tap water due to the age or condition of pipes, plumbing materials and fixtures or other factors. For this reason, customer awareness and education are important components of the LCR and state and water utilities lead reduction programs.
