Why do we test for total coliforms and fecal coliforms in water?

| 2

Fecal coliforms are a good indicator of contamination from human or other animal waste products and they indicate greater risk of exposure to pathogenic organisms than total coliforms. Each person discharges from 100 to 400 billion fecal coliform organisms per day. Some animals discharge much more. A water system tests for these bacteria routinely. If EPA’s safety standards for these contaminants are exceeded, your water system will take action to correct the deficiency, and in the interim, issue an alert with guidance on how to protect you and your family. If you are on a private water system, the local health department will assist you, for a fee, in regularly testing your water supply for these organisms and pathogens.

Pathogens are relatively scarce in water, making them difficult and time-consuming to monitor directly. Instead, fecal coliform levels are monitored, because of the correlation between fecal coliform counts and the probability of contracting a disease from the water. Cities and suburbs sometimes contribute human wastes to local rivers through their sewer systems. A sewer system is a network of underground pipes that carry wastewater. In a separate sewer system, sanitary wastes (from toilets, washers, and sinks) flow through sanitary sewers and are treated at the wastewater treatment plant. Storm sewers carry rain and snow melt from streets, and discharge untreated water directly into rivers. Heavy rains and melting snow wash bird and pet wastes from sidewalks and streets and may "flush out" fecal coliform from illegal sanitary sewer connections into the storm sewers.

In a combined sewer system, sanitary wastes and storm runoff are treated at a wastewater treatment plant. After a heavy rain, untreated or inadequately treated waste may be diverted into the river to avoid flooding the wastewater treatment plant. To avoid this problem, some cities have built retention basins to hold excess waste water and prevent untreated wastes from being discharged into rivers. Without retention basins, heavy rain conditions can result in high fecal coliform counts downstream from sewage discharge points. That is why it is important to note weather conditions on the days before a fecal coliform measurement.
