The question I want to answer:The question I want to answer:

Can we test different stages of the water Can we test different stages of the water cycle runoff from grass & turf fields to see:cycle runoff from grass & turf fields to see: is one more toxic than the other?is one more toxic than the other? could the water hurt plants, people, animals or could the water hurt plants, people, animals or
