I just read through some of the recent Select board minutes for Brookline....WOW, unfortunately the type of childish behavior that many of these board members exhibit is fairly common in small town NH politics. Select boards wield far too much power for elected officials. There are no qualifications to be a select board member and often in small towns people run unopposed, same with state representatives. I used to work in a town on the coast right on the border, everyone knows it, select board members were always getting involved where they don't belong and creating major issues and liabilities for the town. I wouldn't expect the knuckleheads running your town to be any different. If you want to message me I can help you look up your well drilling records filed with the state, I would also do as I mentioned and inquire about your occupancy permit. But as everyone else has said you really need a lawyer and don't waste your time dealing with the Town you will likely get nowhere because they know very little about hydrology and actual laws. Small towns sub out all engineering, legal, and usually only have a part time building inspector that they share with other towns.
