The Shocking Truth About Well Water in America

Before we name names, let's talk numbers. Because what's hiding in 1 out of every 4 wells in this country isn't just gross — it's genuinely alarming.

The RealityThe Number
| US households relying
Private wells the EPA does NOT regulate100%
Wells with at least one contaminant above safe levels23%
Common contaminants found in untreated well waterOver 90
Average lifespan of a quality whole house filter8-12 years
Average cost of well water-related plumbing damage$3,400/year

Read that again. The EPA regulates zero percent of private wells. That means the only person standing between your family and whatever's in that groundwater... is you.
