This should have been brought up during the debate, Re: GM given special hook-up to clean water.

While the Children in Flint Were Given Poisoned Water to Drink, General Motors Was Given a Special Hookup to the Clean Water. A few months after Governor Snyder removed Flint from the clean fresh water we had been drinking for decades, the brass from General Motors went to him and complained that the Flint River water was causing their car parts to corrode when being washed on the assembly line. The Governor was appalled to hear that GM property was being damaged, so he jumped through a number of hoops and quietly spent $440,000 to hook GM back up to the Lake Huron water, while keeping the rest of Flint on the Flint River water. Which means that while the children in Flint were drinking lead-filled water, there was one — and only one — address in Flint that got clean water: the GM factory.
