Summary
The EPA is extending the deadline for public comments on a proposed rule to set safety limits for radon in drinking water. Radon is a naturally occurring radioactive gas that can dissolve in groundwater and pose health risks if consumed in high amounts, so this rule aims to protect Americans' drinking water safety.
Key Points
- 1The EPA is proposing to establish maximum safe levels of radon-222 (a radioactive element) allowed in public drinking water supplies
- 2The public comment period is being extended, giving Americans more time to submit feedback and concerns about the proposed safety standards
- 3Radon in drinking water primarily affects people who rely on private wells or public water systems that draw from groundwater sources
- 4Water utilities would need to test for radon and implement treatment methods if their water exceeds the proposed safety limits
- 5This is still in the proposal stage, meaning the final rule has not been finalized and will be shaped by public feedback received during the comment period
