In 2014, the city of Flint, Michigan changed its water treatment practices allowing lead to leach into the city's tap water. This contamination continued for years as local and state officials provided inaccurate information about safety concerns and resulted in residents being exposed to drinking water with elevated lead concentrations and negative impacts on health.

Multiple lawsuits have been filed against local and federal government agencies and companies, including Veolia North America and Lockwood, Andrews & Newnam (LAN). LAN was accused of failing to implement corrosion control, a treatment for pipes that prevents lead from leaching into the water supply, a decision it says was made by the state and city. Veolia was hired to address drinking water quality. The lawsuit claims that the company’s final report made “fraudulent statements regarding the safety of Flint’s water supply” by stating it met state and federal drinking water regulations.
