They were buying water from Detroit’s water system. In order to save money, they switched to getting it from the nearby river, but they failed to account for how the new water source would interact with their pipes. They didn’t treat the new water correctly and it corroded all their old lead pipes, dumping lead into the water and giving everyone lead poisoning.
Even years later, after they switched back to Detroit water, they’re still having problems because the damage to the pipes is already done.
