E.-coli (Escherichia coli)
E-coli is the most prevalent member of the fecal coliform group. It is a member of the indigenous fecal flora of warm-blooded animals. The occurrence of E-coli in water is considered a specific indicator of fecal contamination and the presence of enteric pathogens.
The current methods for bacterial analysis of drinking water have the ability to check for both the total coliform group and E-coli.
Sample submission
Sample containers may be picked up in all health district offices during regular business hours. Request a bacteriological or Coliform analysis. Samples must be received and setup within 30 hours of sample collection and kept cool during transit.
- When collecting samples take care not to contaminate the sample container.
- Go to a tap where you draw your drinking water and remove aerators, screens, or other devices.
- Turn the water on to a moderate flow and let run for a minimum of 3 minutes.
- Without altering the flow, collect your sample.
- Leave a ½ inch air space at the top of the bottle.
- Cap the bottle and return it to the laboratory as soon as possible.
