| Contact Method/Location: | Office | ||
| Assistance Type: | WATER QUALITY ALERT RESPONSE | ||
| Reasons: | Coliform N/A |
||
| Details: | SUMMARY: Response to TC + routine sample DETAILS: Micah and I spoke about the original TC + routine sample taken on 9/21. System took 3 repeat samples as per sampling plan on 9/22. All repeat samples were coliform absent according to Micah on 9/26/11, so no MCL or corrective action required. No source samples required as wells #1 and #2 are disinfected with adequate contact time and system is performing daily 4-log viral inactivation compliance monitoring under the Groundwater Rule for the wells. This exempts system from triggered source monitoring after a routine positive. ACTION NEEDED: System to take five temporary routines during October. | ||
