Water Filtration Services in Hopkinton, New Hampshire

Merrimack Valley

Hopkinton's wells tap into the granite bedrock common to the Merrimack Valley, which produces arsenic, uranium, and radon. NHDES recommends private-well testing for these naturally occurring contaminants across Merrimack County, and Hopkinton fits that pattern. Arsenic is undetectable without a lab test, and uranium and radon commonly appear alongside it in deeper bedrock wells. Iron and manganese staining is common in shallower wells and in lower ground near the Contoocook River, which runs through the heart of town. Hopkinton's agricultural history makes nitrate testing worthwhile for homes near current or former farmland. Hardness is widespread. Surface-influenced wells near the river or the town's ponds can be more prone to bacterial contamination and seasonal turbidity. A baseline PFAS panel is a reasonable addition given how broadly low-level PFAS has been found across New Hampshire.

Services in Hopkinton

What we install here.

Hopkinton well homes generally get a full panel covering arsenic, uranium, radon, iron, manganese, nitrate, hardness, and PFAS. Systems are built around the findings: whole-home arsenic removal, radon aeration, iron and manganese filtration, and a softener are common, with an under-sink reverse osmosis unit for drinking water. UV disinfection is added for surface-influenced wells where bacteria is documented. We handle NHDES PFAS rebate paperwork up to $5,000 for qualifying homes. Free on-site testing drives the system design.
