The existence of lead pipes in municipal water systems and service lines connecting residential and commercial properties to water mains throughout the United States continues to generate litigation and regulatory action. The U.S. government reported in 2023 that more than 9.2 million American households connect to water through lead pipes and lead service lines. The water crisis in Flint, Michigan, that arose a decade ago and gained national prominence involved water allegedly contaminated both by a change in water source and the presence of old lead service lines. That case, involving over 25,000 individual lawsuits as well as class actions, is approaching an important milestone as a partial settlement nears conclusion.
Background
The Flint water crisis began in April 2014 when the City of Flint switched its source of municipal water to the Flint River. For decades previously, Flint had received water from Lake Huron that was pre-treated by the Detroit Water and Sewerage Department. Following the switch, residents soon reported that “there was something wrong with the way the water looked, tasted, and smelled, and that it was causing rashes.” Tests showed the presence of bacterial contamination. In response, the City treated the water with additional chlorine, which was alleged to have exacerbated the corrosion in the old water lines and allegedly the “corrosion contaminated the water with hazardous levels of lead.” Subsequently, it was alleged that lead monitoring showed results exceeding the Lead and Copper Rule’s action levels for lead, and that a published study showed a spike in the percentage of children in Flint with elevated blood lead levels.
