The Pittsburgh water crisis arose from a substantial increase in the lead concentration of the city's water supply. Although catalyzed by the hiring of cost-cutting water consultancy Veolia in 2012, and an unauthorized change of anti-erosion chemicals in 2014, this spike in lead concentration has roots in decades of lead pipe erosion. Since the Pittsburgh Water and Sewer Authority (PWSA) first failed its water quality test in 2016, it has exceeded the federal lead threshold of 15 ppb by almost 1.5 times. This level of lead contamination poses serious health risks to residents, particularly children and pregnant people. In an attempt to remedy the situation, the PWSA has begun removing lead pipes from the city's water lines and has decided to introduce orthophosphate to the water supply.
