Pittsburgh water crisis

The Pittsburgh water crisis, marked by elevated lead levels in the city's water supply, stemmed from decades of lead pipe corrosion, exacerbated by changes in anti-corrosion chemicals. In 2016, the Pittsburgh Water and Sewer Authority (PWSA) exceeded the EPA's lead action level, posing health risks, especially to children. The PWSA has taken corrective actions to address non compliance with the EPA Lead and Copper Rule and has replaced over 13,000 public lead service lines since 2016. Their goal is to replace all residential lead service lines by 2027. Since 2020, the Authority has been in compliance with the EPA Lead and Copper Rule.
