If you've owned a home in Connecticut for more than a decade, you know about the foundations.
Starting in the 1980s, a quarry in Willington supplied concrete aggregate contaminated with pyrrhotite. That's an iron sulfide mineral. When water and oxygen reach it, it expands and cracks concrete from the inside. Thousands of homes across northeastern Connecticut had foundations that were quietly disintegrating. The damage stayed invisible for years. By the time cracks appeared, the structural integrity was already compromised.
The homeowners who discovered the problem faced a nightmare: insurance companies denied claims because pyrrhotite wasn't listed as a covered peril. The state took years to acknowledge the scope of the problem. FEMA declined to help. The quarry was long gone. Nobody was responsible. The homeowners were on their own.
It took years of advocacy, legislative battles, and the creation of a dedicated state fund before Connecticut homeowners got any meaningful relief. Many spent hundreds of thousands of dollars on foundation repairs with no reimbursement. Some lost their homes.
State Representative Jaime Foster, who represents East Windsor and has worked on well water contamination cases, made the comparison explicitly: "Well water contamination is like crumbling foundations was: no one is responsible, no one is taking ownership."
She's right. And the parallel is closer than it first looks.
Why Does the Well Water Crisis Mirror the Foundation Disaster?
Both crises share the same architecture of failure.
Invisible damage: Pyrrhotite stayed hidden until cracks appeared, sometimes years after the damage began. Well water contamination is invisible by definition. You cannot see PFAS, lead, nitrates, radon, or uranium in your water, and you can't smell or taste most of them either. The damage accumulates quietly.
No mandatory testing: Connecticut required no testing for pyrrhotite in concrete aggregate. Connecticut requires no ongoing testing for private well water after the initial construction test. In both cases, the absence of a requirement created a false sense of security.
No insurance coverage: Homeowner's insurance doesn't cover pyrrhotite damage. Homeowner's insurance doesn't cover well water contamination or the cost of remediation. In both cases, the financial burden falls entirely on the homeowner.
Bureaucratic buck-passing: The Giroux family in East Windsor spent four years trying to get two state agencies, DEEP and DPH, to agree on whose responsibility their contaminated well was. The crumbling foundation homeowners spent years trying to get the state, FEMA, and insurance companies to acknowledge the problem. In both cases, the homeowner was caught between agencies that each said the problem belonged to someone else.
What Can Well Owners Do That Foundation Owners Couldn't?
One difference matters a lot. The well water crisis is preventable at the individual level, right now, for a few hundred dollars.
There's no practical, affordable way to test a foundation for pyrrhotite before you buy a house. But you can test your well water comprehensively for $200-$500. The labs are certified, and the treatment options already exist.
The crumbling foundation crisis needed a political fix because there was no individual one. Well water is different. A political fix (mandatory ongoing testing, state support for remediation, clearer agency responsibility) would still be better. You just don't have to wait for it.
The Specific Risks Right Now
Statewide private well testing is now revealing a consistent pattern of contamination in Connecticut wells:
Uranium is being found in elevated levels in eastern Connecticut, particularly in areas with granite and gneiss bedrock. Uranium is a heavy metal and a radioactive element. Long-term exposure increases kidney damage risk and cancer risk. It is not included in the standard mortgage water test.
Arsenic occurs naturally in Connecticut's geology and is found in elevated levels in wells across the state. According to the ATSDR's toxicological profile, long-term arsenic exposure increases risk of bladder, lung, and skin cancers.
PFAS is being found in wells far from obvious industrial sources. PFAS travel through soil and groundwater over long distances. A well that was clean five years ago may have PFAS today.
Nitrates are elevated in agricultural areas and can spike dramatically after storm events, as the Giroux family in East Windsor discovered.
The Action That Doesn't Require Waiting for the State
Test your well, and ask for the comprehensive panel rather than the basic one. Name the contaminants: PFAS, radon, uranium, arsenic, nitrates, bacteria, iron, and manganese. Use a CT DPH-certified lab.
Want ZIP-level context before deciding whether to test? Enter your ZIP code at CheckYourTap.com to see available public-system or regional monitoring records associated with the ZIP. This is not a test of a tap, well, or property. Free, in 30 seconds.
If you find contamination, the cleanup options work. Reverse osmosis removes PFAS, arsenic, uranium, and nitrates. Aeration removes radon, and ion exchange removes nitrates. None of this is experimental. Plumbers install these systems in Connecticut homes every year.
The foundation crisis became a disaster because no individual fix existed and the state moved slowly. Wells don't have to end the same way.
