Water Well Drilling Contractors in Massachusetts

Geology & Depth

Massachusetts bedrock is primarily crystalline igneous and metamorphic rock — granite, gneiss, and schist — that requires wells to intersect water-bearing fractures. Cape Cod and the Islands rest on glacial outwash sand and gravel, providing productive shallow wells.

Most residential wells in Massachusetts are drilled to 270 feet, with a typical range of 80–600 feet. Water table depth: 15-50 feet on Cape Cod; 80-300 feet in bedrock areas of central and western Massachusetts.

Permits & Licensing

Massachusetts requires water well drillers to hold a permit from MassDEP. Only registered well drillers may construct water supply wells. No homeowner exception.

Permit authority: Local Boards of Health issue well permits under Massachusetts Department of Environmental Protection (MassDEP) regulations. Expect $100-$500 in permit fees.

Primary Aquifer

Fractured Crystalline Bedrock Aquifers / Cape Cod Glacial Outwash Aquifer. About 20% of Massachusetts households use private wells, primarily in central and western Massachusetts and on Cape Cod.

Best drilling months: April through November; deep frost and rocky ground make winter drilling difficult and expensive.

Common Water Quality Concerns

Massachusetts well water commonly contains: radon, arsenic, uranium, manganese, iron, PFAS contamination. A comprehensive water test after drilling (typically $150–$500) will identify which treatments, if any, your well needs.
