More than lead
A place, a sample, and a notice
Lead in drinking water is the first threat we ship.
The same water-system page can later hold PFAS, nitrates, boil-water notices, air, and soil.
| Threat | Status | Category | Thresholds | Why it fits |
|---|---|---|---|---|
| Lead | Live now | drinking water | action 15 ppb · health 1 ppb | Leaches from service lines, solder, and fixtures. There is no safe blood-lead level. Official 90th-percentile sampling can miss individual homes. |
| Copper | Live now | drinking water | action 1.3 ppm | Corrodes from pipes and fixtures. Often travels with lead and is included in certified lead-and-copper kits. |
| PFAS | Coming next | drinking water | health 4 ppt | Persistent industrial chemicals. Official monitoring is uneven. The same water-system page and alerts can hold later PFAS results. |
| Nitrate | Coming next | drinking water | action 10 mg/L | Agricultural and septic contamination, especially in private wells that sit outside Safe Drinking Water Act coverage. |
| Arsenic | Coming next | drinking water | action 10 ppb | Geologic and industrial. High-stakes for well communities and some small systems. |
| Disinfection byproducts | Coming next | drinking water | action 80 ppb | Form when chlorine reacts with organic matter. Official data already tracks this at the plant. |
| E. coli / boil-water | Coming next | drinking water | — | Acute microbial risk. Fits existing boil-water notices. |
| Fine particulate matter | Later | air | — | The same place page and alerts can later hold air data. |
| Soil lead | Later | soil | — | HUD Healthy Homes and childhood lead programs already fund paint and soil work. |
