Details: SUMMARY: Drilling New Well with Correct Construction Guidance DETAILS: (2 of 3 contact reports)

……

2. Without a well report or other relevant data concerning well construction, we cannot approve this well for use. The options available are to reconstruct the well or to abandon the well and drill a new one consistent with state standards.
3. The new well must be cased and sealed through the sand and gravel at least five feet into the bedrock.
4. Given that the aquifer in question is likely to be fractured bedrock, and unless it is located at least 500 feet from surface water, we normally would require monthly coliform testing of raw water to evaluate the potential of surface water influence.

(continued in next contact rpt) ACTION NEEDED: Go through Plan Review

Drill new well

Seal casing 5 feet into bedrock.

Abandon old well or maintain it as an emergency well.

Ascertain whether Surface Water Influence needs evaluating in new well by water quality parameter analysis (i.e. oxygen deficient conditions)
