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

Details:	SUMMARY: Routine +TC/+EC DETAILS: Jennifer notified the OHA-DWS today that two routine samples collected yesterday 11/19/12 were positive for total coliform and one of those was also positive for E. coli. Three repeats were collected today at each routine positive location and results will be available tomorrow morning. She indicated that it was raining really hard when the samples were being collected and the location is under some trees, otherwise there are no other theories for a cause. Tigard is currently on Portland water only and not receiving water from Lake Oswego or their groundwater wells. Total chlorine residual was normal for the area at the time of sampling. The two locations with positives are across town from each other. ACTION NEEDED: No further action needed at this time-- we will wait for results from repeat sampling and respond accordingly.
