These organisms inhabit the intestinal tract of warm-blooded animals, hence their presence in water shows sewage contamination or pollution Minus sign, gas absent. from surface drainage. Plus sign, gas present. One part per million is equivalent to 1 pound of substance per million pounds of water. One gallon weighs 8.33 pounds. 17.1 parts per million=1 grain per gallon. . AP wt
