"This memo ways even the best-centralized treatment used by a public water system may not prevent the release of lead particles, particles that can be up to 97 percent lead."
"The memo points out that neither the states nor small or medium water systems have the expertise to establish optimal water quality parameters that will ensure lead levels are well controlled."
"The memo points out that a lot of water systems don't know where their lead service lines are and thus may be missing high lead levels when they go out to sample."
"According to the memo, sampling just the first liter of water to come out of the tap rather than the fifth or tenth liter, missed the peak lead values 100 percent of the time."
