MA DEP is now determining whether a cross-connection problem may exist. Seems like there should be a way to insure it isn't a problem. Also, we determined that the well would be private and not public ( a private well is allowed for business, public is not).
The main concern is the presence of a restroom. I have one, but it is in my detail shop, which is a separate building with a separate water connection. This means the well would be for carwash only and therfore categorized as 'private'.
The impetus behind this latest round of due diligence was the arrival of last quarter's water/sewer bill.
