The LRM sent out well water questionnaires to well owners for purpose of determining well water level. To date some of us have not heard back. Perhaps it would not be a bad idea to request the LRM to conduct an analysis of the well water for contaminants as well.
Reason: To be able to establish a BASELINE in the event that a claim against contamination from the excavation arises.
For the record: This is not legal advice. I am not a lawyer, just a concerned resident exercising due diligence to help safeguard health, safety and interest of the community.
