1 above health guidelines7 contaminants detected

Every reading above guidelines, measured

All 1 of them, worst first, from Lyndon's own published tests. Tap any contaminant to see what it is, how it gets into the water, and what long-term exposure is linked to.

Radium (-226 and -228)3.31 pCi/L / 0.05 pCi/L66x over

Long-term exposure: Radium is radioactive. The body treats it like calcium, so it deposits in bone, and long-term exposure raises bone cancer risk.

Northern Illinois sits on a deep sandstone aquifer that is naturally radioactive. The radium comes up with the water. The federal limit of 5 picocuries per liter was set in 1976 and has not been revisited since.

Handled by: Water softener (EPA-recognized ion exchange), or reverse osmosis

Levels are the utility's own most recent published test results as compiled by the EWG Tap Water Database. "Times over" compares against EWG's independent health guideline, not the federal legal limit; this system meets federal limits.
