The company is a member of the Maine Groundwater Association and the National Ground Water Association. Pine State self-identifies as an IGSHPA member on its website; however, the company does not appear in the 423-member IGSHPA directory scraped in May 2026, so igshpa_certified is set to 0 per strict-directory policy.
