Contamination and Pollution FAQs - 27 Found
First let's talk about what E. coli is. It is a type of bacteria commonly found in the intestines of animals and humans. The presence of E. coli in water is a strong indication of recent sewage or animal waste contamination. The full fact sheet is on the web at: Basic Information about E coli 0157:H7 in Drinking Water
Public water supplies are usually disinfected with chlorine, ozone, or some other process. Finding E. coli in a public water supply indicates that the disinfection process was not working, or that contact with the waste occurred after the water was treated. If your sample was from a public water supply, you should notify the supplier.
If you suspect the water source, whether public or private, may still be contaminated, you should consider drinking bottled water, boiling your drinking water, or treating it with iodine, bleach, or disinfection tablets.
