Assistance Type:	WATER QUALITY ALERT RESPONSE
Reasons:	Coliform N/A

Details:	SUMMARY: MCL- repeat total coliform positive samples DETAILS: I met up with Mike & David Jacob for a water system survey. I asked about the total coliform positive samples. David indicated that well # 7 was off when the samples were taken. The chlorinator is triggered off of well # 7 so chlorine was not being injected. This has been correct to provide chlorination when any of the wells are running. This will prevent the system from being without residual maintenance chlorination. He said the public notice will be sent to DWS. I let him know to be sure to take 5 temp routine samples in January. ACTION NEEDED: Obtain copy of public notice & monitor follow ups.
