How is a water supply affected by run off from nearby dairy farms?
Runoff from dairy farms not only includes bacteria from cow droppings but can also include items such as phosphates and other minerals that can have negative effects. As far as how it effects the water, the cow droppings can carry e-coli bacteria (which will cause severe intestinal problems in humans), the phosphates/misc minerals can incourage growth of water organisms that will choke out the waters natural oxegen content. Those are the 2 main big issues w/dairy farm runoff.
