How Orevant uses the SDWA
The Safe Drinking Water Act is the federal law that authorizes EPA drinking water rules for public water systems. 40 CFR Part 141 is the regulation written under it. This page is the source note, not a history of the Act.
What we point at
- The Act as the authority
- 40 CFR Part 141 as the National Primary Drinking Water Regulations
- EPA SDWIS as the inventory and violation file
Public notice tiers and deadlines stay on the blog: SDWA public notice tiers.
What we will not claim
- If we cannot point at the regulation, we do not say it.
- Unable to Verify is not a violation.
- This is not legal advice. Verify with your primacy agency.
- Orevant does not report your system to EPA or the state.
The $199 Complete System Report is the cited document. Orevant Pro is $87/month or $870/year.
