anyone catch the NBC4 news last night ? they had some scientific-type guy testing the water at 4 central Ohio reservoirs. They tested Alum, Griggs, Hoover, and Delaware. They wanted an answer to which of these reservoirs is the cleanest/dirtiest. To my surprise, Griggs was fine. ALUM was by far the nastiest. Some kinda e-coli and other assorted nastiness around the beach area. The guy who did the test said that he would not let 'his' family swim there. Hoover was the cleanest.
