* Gas in the fermentation tubes and confirmatory test indicate the presence of bacterial organisms of the Coli-Aerogenes group. These
organisms inhabit the intestinal tract of warm-blooded animals, hence their presence in water shows sewage contamination or pollution
from surface drainage. Plus sign, gas present. Minus sign, gas absent.

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.
