My concern is .... if this chemical can affect small roadside streams, then how about the same runoff from roadside traffic all around our local lakes and streams? Combine this with the runoff of "nutrients" spread by farmers and all the rest of the toxic substances entering those same lakes & streams. Are any departments currently testing for this chemical buildup?
