Uranium in Vermont well water
In Vermont, 1% of 19,240 private wells tested had uranium above the Vermont limit (20 ug/L), according to the Vermont Department of Health.
Uranium in well water comes from granite bedrock. Its main health effect is chemical toxicity to the kidneys rather than radiation. It is common in the same areas where radon and arsenic occur.
Check your uranium number
Type the value from your lab report. It is compared to the Vermont limit and the EPA limit, the same way the full interpretation does it.
