The date we have here is just the opposite of what we saw the first time we sampled from these same sites.  During the first series, we saw slightly higher coliform counts in the beginning, after country systems and before south side huntington. This second time, we saw higher coliform counts after the south side and lower counts after the country systems vs. after south side.  Another difference is that there were significantly higher coliform counts when counting the sum of both before and after in this last experiment. This is probably because the creek was higher, following heavy rain the day before, which seems to lead to a "catching" of leachate from septic tanks in the country and possibly broken sewer lines on the south side.  We will need to repeat these sites once more and try to arrive at some   conclusions from the data.
