Uranium in Oklahoma well water
In Oklahoma, 8% of 1,135 tested private well samples exceeded the EPA limit for uranium (30 ug/L).
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 EPA limit, the same way the full interpretation does it.
