ConsCom approves drilling on O'Rourke
Robert Cataldo, senior hydro-geologist from ENSR, attended the August 10 meeting of the conservation commission to present plans for a groundwater-pumping well and monitoring well on the O'Rourke Farm, now the property of U.S. Fish and Wildlife Service. Cataldo described the selected location as a wetland area where he believes they will find 50-60 feet of productive aquifer. They will drill one production well in the most promising location and then drill one or two monitoring wells nearby to observe any side effects on the water table. The cuttings from all drillings will be contained and removed.
After the drilling is complete, Cataldo will install a submersible pump and test gallons per minute (GPM) water flow. "We hope for 80-90 GPM, but maybe we'll hit bedrock at ten feet and only get three GPM," said Cataldo. If they do strike a "glory hole," he plans to hook the hose to a tree and spray the water over a wide area to limit spiking or other surface damage. The water will be analyzed for various minerals and toxins as part of the overall water quality evaluation. "If all goes well, we can come back to the town and say that this is a viable area," explained Cataldo. "This is the first of four or five steps before we can qualify a municipal water supply." ConsCom members gave Cataldo a unanimous go-ahead with a vote of 4-0.
