Most homeowners have no idea their tap water contains PFAS "forever chemicals", their walls are coated in lead paint, or invisible radon gas is seeping through their foundation.

The average American home contains multiple invisible health hazards. These aren't dramatic failures—they're slow-acting toxins that accumulate over years.
Homes built before 1978 almost certainly contain lead paint. Pre-1980 homes may have asbestos insulation. Aging infrastructure means deteriorating pipes and increased contamination risk.
Even EPA-compliant water can contain harmful levels of PFAS, chromium-6, and disinfection byproducts. Lead service lines affect millions of homes across the US.
Radon zones, industrial legacy contamination, and proximity to military bases create localized exposure risks that vary dramatically by ZIP code.
Young children are especially vulnerable. Lead exposure causes permanent brain damage. Radon is the #1 cause of lung cancer in non-smokers.

Invisible, odorless radioactive gas that seeps through foundations. Second leading cause of lung cancer after smoking.
PFAS "forever chemicals", lead from aging pipes, chromium-6, arsenic, and disinfection byproducts in municipal water.
Banned in 1978 but present in 38 million US homes. Deteriorating lead paint creates toxic dust that causes permanent developmental damage in children.
Hidden mold from moisture issues, poor ventilation, VOCs from building materials, and indoor air pollutants.

All hazard data is compiled from official government sources: EPA radon zone maps, US Census housing age data, state water quality reports, CDC lead exposure studies, and municipal contamination records.
Yes. Our reports show community-level risk, but individual homes can vary dramatically. A "Low" radon zone doesn't guarantee your basement is safe. We recommend testing regardless of risk level, especially for radon and lead paint.
Start with testing to confirm the specific hazard. For radon: use a detection kit. For lead paint: test surfaces with swabs. For water: order a lab test. Each city report includes specific testing recommendations and product links.
