Water testing for Connecticut private wells
About 342,000 private wells serve roughly 23% of Connecticut residents — and unlike public water, no utility tests them for you. Testing is the first step, before anyone sells you treatment.
Fairfield Well Water connects Connecticut well owners with one licensed local well & water-treatment company — fast. We are a referral service, not a contractor.
Why test?
Connecticut's Department of Public Health (DPH) urges all private-well owners to test their water. Many of the things worth knowing about — arsenic, uranium, radon in water, lead — have no taste, smell, or color. A lab test is the only way to know what's actually in your water, and it's the only honest basis for choosing treatment.
What a test typically covers
- Bacteria (total coliform / E. coli) — the basic safety screen, worth doing annually
- Arsenic — naturally occurring in some Connecticut bedrock; only a lab test reveals it
- Uranium — also naturally occurring in parts of the state
- Radon in water — a separate test from indoor-air radon
- Lead — usually from plumbing, not the well itself, but the test catches it either way
- pH and hardness — acidic water corrodes pipes; hard water scales fixtures and shortens appliance life
- Iron and manganese — the usual cause of rust staining and metallic taste
When to test
- When you buy a home on a well, and annually for bacteria after that
- After flooding, nearby construction, or any work on the well or pump
- When taste, smell, color, or staining changes
- When a baby is expected or someone in the home is pregnant — testing is a sensible precaution
- Before buying any treatment system — treatment should follow test results, not replace them
How testing works
- Send a request through the form — choose "Water test" as the problem.
- The specialist arranges sampling. A proper sample follows lab instructions (correct bottles, correct tap, no contamination), so results you can trust.
- A certified lab analyzes the sample and the specialist walks you through the results in plain language.
- Treatment only if the results call for it. If results come back clean, the honest answer is that you don't need treatment — and the specialist will say so.
Our test-first rule: anyone quoting treatment without lab results is guessing with your money. If a result shows a problem, treatment is chosen for what the lab actually found — never the other way around.
What does testing cost?
Testing costs vary with how many parameters the lab analyzes; your specialist will confirm the price before sampling. We never charge homeowners anything for the referral itself.
