Starting on Monday drilling begins for two 300-foot deep geothermal boreholes that will support our ground source heat pump. The crew arrived today to set up the rig and excavate a slurry pit. I am glad I was onsite because they were going to locate the boreholes using Massachusetts state setback regulations rather than the more stringent ones mandated by the town of Concord. It would have been a very expensive mistake had I not intervened. Ideally, we would like to hit bedrock quickly and not find any water but Murphy’s Law suggests just the opposite will be true. Drilling is expected to take three days so we should know the answers by mid-next week.
