The fastest-growing water pollution threat in my region – and probably in yours, too – is stormwater, that filthy mixture that results when rain or melting snow washes away oil, antifreeze, dog poop, fertilizer, pesticide and anything else on the ground. It is truly foul stuff.
All that ends up somewhere. Usually, that's your nearest stream, wetland or bay. And the rainwater running off streets and other hard surfaces tends to come in big surges that gouge out stream bottoms.
