For a long time the US Dept. of Transportation had a restriction against taking on water (trains and planes) in Pascagoula, Mississippi. This water was so bad that the first time I went into the company loo to take a wiz I thought there had been several other guys ahead of me that had neglected to flush the john. I flushed the john and the color of the water did not change. Most restaurants and homes had filtration systems installed to bring the water to a consumable state.
