The experts are looking for the pump tests to indicate one or all of the test wells will produce at least 150 gallons of water a minute each to make them worthwhile to pursue.
The pump testing should be conclusive in about two months, Bell and DeNatale said, when they will return with their report to selectmen, and the next steps will be decided.
Replacing bedrock well 4 is another option on AECOM’s plan. Installing up to two test wells adjacent to the existing, failing well to replace it would cost about $87,000, Bell estimated.
Selectmen will look at this again in two months, they said, after they learn the results of the approved pump testing.
