New tests show lead in Pittsburgh drinking water doesn’t exceed EPA limit, but officials aren’t celebrating yet

Even though there is near-universal agreement that it is unsafe to consume any lead, the EPA’s “action limit” is an indication that water systems have to make changes to reduce lead levels if they go above it. The state had ordered the PWSA to conduct this regular water testing after an unauthorized switch in corrosion chemicals that is widely believed to be linked to an increase in lead levels.
