Goodwin Well & Water, Inc. has served Maine homeowners, businesses, and municipalities from their Turner facility since 1948, bringing over 75 years of groundwater and geothermal experience to every project. As an IGSHPA-listed Ground Loop Installer, the company offers all three geothermal well configurations: Standing Column Wells, closed-loop borehole systems, and open-to-recycle installations. Their in-house Standing Column Well design tool optimizes thermal performance for each site's specific geology and load profile. Well services extend beyond geothermal to include residential and commercial water well drilling, pump installation and repair, and water quality testing and treatment. Goodwin draws on familiarity with Maine's varied geological conditions across Androscoggin and Oxford counties, connecting each project to durable water and energy systems. Membership in both IGSHPA and the National Ground Water Association reflects participation in geothermal loop installation standards and continuing education.
