[....] I would know, as I did the experiment. I took tap water from lake Michigan and filled a tall clear bottle with it. I then put it in a place where it wouldn't be disturbed for 72 hours. After that time, I took the bottle and looked at the bottom, where a thick brown sediment had settled. My best guess is that is human fecal material at the bottom of the bottle. Invisible at first because it is in suspension, but given the opportunity for gravity to work on it, the accumulation is quite pronounced, and of the appropriate brown color. As far as dissolved chemicals are concerned, they remained in solution. I attack both problems with sediment and activated carbon filters. I know someone who died from cancer...her doctor said it was most likely from drinking the water ( Steger Illinois, which I think is/was wellwater until we got a feed from Lake Michigan through a Chicago Heights distribution station ). In summary, I would not feed tap water to a stray DOG, without first filtering it through sediment and activated carbon/charcoal filters to remove _most_ of the impurities. There remains the *heavy metals* problem, but those filters are way way expensive. Activated carbon/charcoal with a pre-filter for sediment provides a Good Return on Investment (ROI). I have two of them in series, for drinking water purposes only. Nobody at this house drinks water from any source that isn't first filtered with my own equipment. Lg Chicago ( far South Side ) Lg - smart person, good job for your work. Thanks Jim, Here is my response to those that think I was looking at IRON precipitate.* THAT'S A HELL OF A LOT OF IRON! We're talking 1/16th deep LAYER of this *stuff.* If it is human feces, it is _dead_ human feces, but feces none the less. I surely doubt any of the Great Lakes have that much feces, human or cattle or pig or total in any way! I do suspect you overestimated the thickness of the sediment layer, especially as averaged over the bottom surface of the container. But even if it was only .02 or .01 inch thick if made even in thickness, I don't see any of the Great Lakes having that much poop even if all the cowpies from Wisconsin and all the sewage and dog poop, cat poop, rat poop, mouse poop and roach poop and flyspecks from Chicago and its suburbs and poop from all livestock in Chicago's stockyards got dumped into Lake Michigan with no treatment. I suspect most of this stuff is iron compounds and ordinary dirt. Also, I do not see a need for zero tolerance of fecal matter in water but some sort of "safe level". Humans evolved in areas where I doubt they were upstream of every fish in the nearest creek, as well as runoff from land pooped on by animals let alone the next village upstream! - Don Klipstein ) |
