While performing research into premature pipe corrosion for the District of Columbia Water and Sewer Authority (WASA) in 2001, Marc Edwards, an expert in plumbing corrosion, discovered lead levels in the drinking water of Washington, D.C., at least 83 times higher than the accepted safe limit.
Under the LCR, if tests show that the level of lead in drinking water is in the area of 15 ppb or higher, it is advisable—especially if there are young children in the home—to replace old pipes, to filter water, or to use bottled water. EPA estimates that more than 40 million U.S. residents use water "that can contain lead in excess of 15 ppb".

The EPA, which regulates public drinking water, advises a safety level of below 70 parts per trillion for the two most-studied PFAS chemicals. This is considered voluntary guidance. This is ...
The accepted limit for lead in drinking water is 15 parts per billion (ppb). Edwards's meter, which could read values up to 140 ppb, showed off-the-scale readings even after he had diluted the sample to ten percent of its original strength. [2] The water contained at least 1,250 ppb of lead. [5] "
