Lead Detection in Public Water Systems ‐ (dated 2/25/). This report reviews issues surrounding the elevated lead levels in DC drinking water and actions to address this problem.
More broadly, it discusses the lead regulatory framework, and EPA's national review of the rule and its implementation to determine whether the situation in Washington, DC, denotes a wider problem in need of a broader response.
Lead can enter the home drinking water by leaching from lead service connections, from lead solder used in copper piping, and from brass fixtures. Lead has a tendency to be complexed and precipitated by a large number of substances. Studies indicate that nearly all the lead in users’ tap water does not come from the primary water source or from the municipal treatment plant, but is a result.
Lead profiling is a type of sampling that collects each liter of water from the tap, through the home's plumbing system, and out through the service line to the water main.
