Assistance Type: OTHER REGULATORY - Completed Level 2 Coliform Investigation
Reasons: Coliform
 
Details: Level 2 coliform investigation completed on 07.24.2024.

The failure of the chlorine injection pump was identified as the main cause of the multiple E. Coli samples.

Next steps: The chlorine injection pump was fixed, and the chlorination system is back online. The operator should verify free chlorine concentration is recorded when coliform samples are collected. Recommend using a non-swivel type faucet for coliform sampling to prevent cross contamination. Swivel joints on the faucet can harbor bacteria, creating the potential for bacterial contamination during sample collection.
