Frequently Asked Questions: Drilling Wells in Massachusetts
1. How deep do you usually have to drill for water in Massachusetts?
Across Massachusetts, the median residential water well is drilled to 270 feet. However, shallow alluvial wells can hit water as high as 80 feet, while deep bedrock or limestone aquifer wells may require drilling down to 650 feet to reach sufficient pressure and yield.
2. How much does a complete water well cost in Massachusetts?
On average, homeowners in Massachusetts invest $15,800 USD for a complete turnkey system. Drilling alone costs $54 per foot (ranging $38–$88/ft), while submersible pumps, pressure tanks, state permit fees ($225), and electrical hookups comprise the remaining balance.
3. What is the required setback from septic tanks in Massachusetts?
State health mandates overseen by the Massachusetts Department of Environmental Protection (MassDEP) require a minimum separation distance of 100 feet from any septic tank, leach field, or potential contamination source, plus at least 25 feet from adjacent property boundaries.
4. What is the groundwater quality like in Massachusetts?
Wells in Massachusetts typically yield water with a hardness reading around 75 PPM and an average pH of 6.5. Key minerals present in natural groundwater include Iron, Manganese, Radon in bedrock, PFAS concerns in localized areas. The recommended standard filtration configuration is: Whole House Carbon + Calcite Neutralizer + Iron Filter.
