YikesI was on a construction project some years back and noticed a frozen pipe on a tanker load of "curing compund" had burst and was getting onto the interstate. Curing compund is a combination of water, wax and kerosene that is sprayed over concrete to hold the surface moisture from evaporating.
This one fellow thought he was helping and moved the truck away from the roadway. Trouble was now this stuff was getting into the storm drain system. The system that drained to the cities main resevior. Uh oh. The tank held about 1000 gallons and the resevior about a billion gallons give or take a few million. Yet it wasn't long before a white cloud began to show on the surface at the edge of the lake.
It was quickly contained, so no harm no foul but..... nearby was what is called a tank farm. As in about 100 tanks of gasoline at about 3 million each. Also nearby was a railroad where large lengths of train cars carrying hazardous chemicals like those in Palestine Ohio is dealing with. It's a very vulnerable water system to say the least. That was one of the few places I've ever lived that I wouldn't drink the tap water. Shoot, I didn't want to breathe the air there either but had no choice in that matter.
