EPA: Corruption and Idiocy At Its Greatest

Heard about the water contamination in Flint Michigan?

The braniacs running the city decided to switch water sources. At this point, the consensus is that the new water is causing lead in pipes to leach back into the system.

Well now. I am no engineer but this reeks of bullshit

How does water flowing into a house, leach lead from pipes, then flow back into the system and into the neighbor’s?
The above post hints that the EPA knew about the tainted water. (I guess they were too busy last year back pedaling and beating around the bush after they dumped a million gallons of toxic waste into a river in Colorado. Not to even mention the fact that they passed legislation to grab more water sources that used to belong to landowners.)
