How to read a uranium result.
The 0.02 mg/L (20 µg/L) MAC, Shield and Atlantic wells, and why waste from treatment needs a plan.
Unit
mg/L or µg/L. 0.02 mg/L = 20 µg/L.
Canadian reference
The Canadian maximum acceptable concentration for uranium is 0.02 mg/L (20 µg/L).
Possible sources
Natural geology in parts of the Canadian Shield, Nova Scotia, New Brunswick and other regions.
What one result cannot conclude
- Clear water is not a uranium screen.
- A total uranium result is not a radiological diagnosis — follow the lab and public-health advice.
Sensible follow-up testing
- Confirm units with the lab.
- Use an alternate drinking supply while you confirm a treatment plan with the laboratory and local authority.
Source correction
Source correction of the aquifer is generally not feasible. Treatment and waste-handling matter.
Certification questions
RO may reduce uranium at a drinking tap when the claim exists. Ion exchange for uranium is specialist work because of residual media and regenerate.
Treatment options
Point-of-use RO is a common drinking-water approach when the claim matches. Test after installation.
