A public-risk map pairs USGS-modeled arsenic and nitrate estimates with a household-size filter selector for private-well users.

Landing page captured for the 2026-08-25 issue.

Field notes

The page combines geographic risk estimates with a treatment workflow: choose a contaminant, enter household size, and receive a recommended system plus cartridge intervals and running cost. Its coverage is unusually explicit, spanning 3,103 counties in 49 states, with state and county figures attributed to USGS studies. The site repeatedly distinguishes modeled probability from direct measurement and directs visitors to test their own well before relying on treatment recommendations.
