John, we did---five samples. If I recall the max e coli level for wading/swimming is somewhere around 380; the pond clocked in at around 1200. The sample taken directly off the pile was 20,100. Spinner----that is brilliant; wished I'd thought of it myself. Only problem is we live too close to the big city. It would help if we lived in my wife's hometown, about 100 miles SW of here, where one day I read the lead story about some college students calling in a bogus order for 5 pies from the local Pizza Hut.
