| Assistance Type: | WATER QUALITY ALERT RESPONSE | ||
| Reasons: | VOCs |
||
| Details: | I called and left a message for Steve Wabschall; water sample test results for 2 VOCs, ethylbenzene and toluene, tested below the MCL but at/above the detection limit. Therefore, I mentioned, a confirmation sample for each chemical, ethylbenzene and toluene are required and the sampling schedule will switch to Quarterly for the time being. I added that if the results end up being reliably and consistently below the MCL for at least 2 of those Quarters, the monitoring schedule may be reduced to Annual. The confirmation sample and recent result for both contaminants will also be averaged to determine compliance. | ||
