How can you tell if water is fit to drink? Color and taste aren't reliable guides for water safety. Clear water can be contaminated with chemicals or microorganisms the senses can't detect. One of the principle qualities of potable (drinkable) water is its freedom from microbial contaminants. This article will describe some criteria and methods that are used to determine the microbial quality of water.

In the mid 70' s, someone noticed that the ratio of two indicator bacteria in fecal wastes - fecal coliforms (FC) and fecal streptococci (FS) - was characteristic of particular animal wastes. In human wastes, the fecal coliform/fecal streptococci ratio (FC/FS ratio) was greater than 4. In domesticated animals, like cattle, the ratio was between 0.1 and 4.0. In wild animals, the ratio was less than 0.1. Since that time, many attempts have been made to use the ratio to determine the source of fecal bacteria in contaminated ground water.
