Have you ever wondered if your drinking water is truly clean? American Water Works Association published a study describing that bacterial and viral indicators of fecal contamination were found in drinking water. Coliforms, E. coli, male-specific coliphages, and somatic coliphages were measured in feces, wastewater samples, and in drinking water samples collected from many different areas and seasons. Coliphages is a virus that affects E. coli and is thought to be a possible viral indicator, which monitors the fate of viruses in water. This experiment was done to compare coliforms and coliphages as indicator organisms in wastewater and drinking water systems. A total of 75 samples from five animal groups and a total of 72 samples from surface water and groundwater were collected and tested. Coliforms and E. coli were found in most of the fecal samples, all wastewater samples, and some drinking water samples. Therefore, it is believed that coliphages survive various conditions and are said to be good indicators of fecal contamination.

This
figure is showing a five statistical summary to help interpret the distribution
of data for raw and primary settled wastewater and untreated and treated
drinking water samples. Turbidity, TOC, pH, and DOC were all taken into account,
showing their specific results within the Raw WW, Final WW, Untreated DW, and
Treated DW. PH showed results in each category. Charest, A. J. et. al (2014)
