Problems With Your Well in Massachusetts? Here's What to Do
Many rural Western Mass homes in Hampshire, Franklin and Berkshire counties rely on private wells. Massachusetts has no statewide private well code; your local board of health sets the rules, and MassDEP publishes guidelines. Start with a test from a state-certified lab, because bad water is often fixable with treatment, while a failed well or pump is a bigger job.
What to look for
- Cloudy, discolored or bad-tasting water
- Rotten-egg smell, staining, or a change after heavy rain or drought
- Sputtering faucets, low pressure or the pump running constantly
- No water at all, or the well running dry in late summer
- A failed bacteria, arsenic or uranium test

DIY or hire a pro?
You can collect water samples yourself using a certified lab's bottles and instructions. Drilling, pump replacement and treatment system installs belong to certified drillers, pump installers and licensed plumbers.
If fixing it is more than you want to take on
Many water problems can be fixed with a treatment system, and having passing test results makes the house much easier to sell and finance. If the well itself is failing, you can sell as-is with an agent and disclose the test results, or sell as-is to a cash buyer, who will close without a passing test but pay less than for a house with a working well.

Common questions
Is well water testing required when selling a house in Massachusetts?
There's no single statewide rule; MassDEP recommends buyers test, and some local boards of health have their own requirements. Lenders often ask for a test too, so check with your town.
What should my well water be tested for in Massachusetts?
MassDEP suggests bacteria and nitrate/nitrite every year, and arsenic, lead, uranium, radon and PFAS at least every ten years. Arsenic and uranium occur naturally in Massachusetts rock.
How much does a new well cost?
Angi's national average is about $5,500, with most homes between $3,000 and $9,000. Deep bedrock wells cost more.
Who regulates private wells in Massachusetts?
Your local board of health. MassDEP issues guidelines and certifies well drillers and labs.
Can I sell a house with bad well water?
Yes. Many problems can be solved with treatment; otherwise disclose the results and price the house accordingly, or sell as-is to a cash buyer.
Are there health risks from contaminated well water?
Some contaminants can affect health. If you're worried about exposure, share your test results with a doctor.
