Carroll Water
Certifications: WQA Certified Water Specialist
Family-run well and water-treatment company founded in 1983, with an office on Hoff Road in Hanover. Advertises radon testing and removal for well water and recommends point-of-entry (whole-house) radon treatment rather than a drinking-water filter, because radon escapes into the air from every tap and shower. Also drills wells and installs pumps, softeners, filters and reverse-osmosis systems. Its Hanover page lists York, Adams, Lancaster, Dauphin and Cumberland Counties among the areas served. A WQA Certified Water Specialist and authorised EcoWater dealer; not on the PA DEP radon mitigation list, which covers radon in air.
