Many Connecticut homes outside the cities run on private wells, and the owner is responsible for the water quality. Common problems are bacteria, naturally occurring arsenic, uranium or radon, hard or iron-heavy water, and a tired pump. Most are fixed with testing, a treatment system or a pump replacement; a dry or failed well may need a new one.
What to look for
- Rotten-egg smell, cloudy water or an odd taste
- Orange, brown or black stains on sinks and fixtures
- Low or surging water pressure, or the pump running constantly
- Sputtering faucets or running out of water
- A lab test showing bacteria or contaminants above limits

Connecticut rules to know
- Connecticut law does not require a well water test when a house is sold; the Department of Public Health (DPH) notes that tests during a purchase are usually required by the mortgage lender (source: portal.ct.gov)
- Under CGS 19a-37, the seller or real estate licensee must give the buyer DPH's educational material recommending private well testing, though failing to do so does not void the sale (source: portal.ct.gov)
- DPH recommends testing basic indicators (including bacteria) every year, and arsenic, uranium and radon at least once and ideally every 5 years, since these occur naturally in groundwater in parts of Connecticut (source: portal.ct.gov)
- A new well needs a well drilling permit countersigned by the local Director of Health, and the driller files a Well Completion Report (source: portal.ct.gov)
- Well construction requires a W-1 water supply driller contractor registration; pump and tank work is also covered by well drilling registrations (source: portal.ct.gov)
Who to call
- A state-certified drinking water lab for testing. DPH lists certified labs and recommends checking the lab is certified for the tests you want (source: portal.ct.gov)
- A registered W-1 well driller or pump contractor. Verify the registration at elicense.ct.gov
- Your local health department for well permits and help reading test results
- A water treatment contractor for filters, softeners or arsenic or radon systems
DIY or hire a pro?
Collecting a water sample with a lab's kit and changing cartridge filters are fine DIY jobs. Pump replacement, well repairs and new wells should be done by a registered well contractor, and a new well needs a permit from the local health director.
If fixing it is more than you want to take on
Testing first and installing a treatment system if needed usually keeps a buyer's lender happy and avoids a last-minute scramble. You can sell as-is with disclosure and let the buyer test, but a bad result mid-deal often means a credit or a lost buyer. A cash buyer won't need lender approval of the water, but will price in the cost of treatment or a new well.
Want a cash offer on the house as it is?
Sell 2 Us buys houses as-is across Connecticut: no repairs, no cleanout, no fees. You pick the closing date.
Common questions
Is well water testing required to sell a house in Connecticut?
No state law requires it, but the buyer's mortgage lender usually does. The seller or agent must provide DPH's educational material on well testing.
How often should I test my well in Connecticut?
DPH recommends testing basic indicators like bacteria, nitrate and hardness every year. Test for arsenic, uranium and radon at least once, and ideally every 5 years.
Is arsenic or uranium in Connecticut well water common?
DPH says arsenic, uranium and radon occur naturally in groundwater in some areas of Connecticut. Only a lab test tells you if your well has them.
How much does a well water treatment system cost?
Angi's national average is about $2,300, with most systems $1,200 to $3,600. Multi-stage systems can cost more.
How much does it cost to drill a new well?
Nationally about $3,000 to $9,000, or $25 to $65 per foot. Deep bedrock wells cost more.
Do I have to disclose well problems in Connecticut?
Yes. The disclosure report asks whether you know of problems with the well or with water quality, quantity, recovery or pressure.
