Private Well Water Testing in Hawaii
Hawaii is outside the USGS national groundwater models, so we don't have county-level well-risk estimates here — but here's how to test a private well in Hawaii.
Private-well testing in Hawaii
There's no USGS national groundwater model for Hawaii — Alaska and Hawaii fall outside the federal arsenic and nitrate datasets we use — so we don't have county-level well-risk estimates here.
If you rely on a private well in Hawaii, test it directly: Hawaii certified testing labs and what to test your well for.
