Reasons:	Coliform N/A

Details:	SUMMARY: Positive coliform 6/8/11 DETAILS: Spoke with Jennifer and she said she is helping with water sampling and that Kat thought that it was likely sampling error that caused the positive. I let her know that they will need a triggered source sample at the wellhead along with 3 repeat samples in the distribution system. I let her know that if all come back absent then they will need 5 temporary routine samples for the month of July. If those come back absent they will count for the 3rd quarter sample and they will be back on 1 per quarter sampling. ACTION NEEDED: Monitor follow up sampling and respond if necessary.
