Reasons:	Coliform None

Details:	SUMMARY: GWR monthly assessment monitoring DETAILS: I was able to release Wells #3, #4, and #5 from monthly assessment monitoring because their only highly sensitive characteristics were unconfirmed organic chemical detects in the 90s, which have since been ND. Well #1 still needs to be sampled because the casing seal is inadequate and the Traverse Potential score is greater than 5. Well #2 still needs to be sampled because the aquifer is shallow and unconfined. Both wells have sewer lines within their 2-yr TOTs. I wrote Lee a release letter for Wells #3, #4, and #5, mailed today. ACTION NEEDED: System must sample Wells #1 and #2 monthly for a year.
