When the sky cries, that’s a natural phenomenon. But when Nature’s pure water mixes with various types of oil and hydraulic fluids or other contaminants, the result is a man-made problem.
Commonly called stormwater runoff, rainwater will flow wherever it wants once it hits Earth. And this characteristic is what makes water troublesome wherever it encounters oil – in heavy equipment yards, scrap yards, truck and train terminals, oil and gas operations, shipping docks and the like. Water from various types of wash-down operations will behave the same way.
