September 29 E.coli results

September 30, 2010

Every other Wednesday from June through September, WRP volunteers test for E. coli bacteria at sites along the White River and its major tributaries. E. coli is a type of bacteria that lives in the intestines of all warm-blooded animals. E. coli is easy to test for, and is therefore used as an indicator for other disease-causing bacteria in the water. In other words, a high E. coli count reveals that a variety of disease-causing bacteria from numerous sources (leaking septic systems, animal waste, etc) are in the water and could make people sick.

The EPA “swimmable” standard is 235 colonies/100 mL sample. Sites exceeding the EPA standard are marked with an asterisk (*).
