How Orevant uses 40 CFR Part 141
40 CFR Part 141 is the National Primary Drinking Water Regulations. When a finding on an Orevant report cites a federal rule, this is the book it is pointing at.
What Part 141 is
Part 141 sets the federal drinking water standards that apply to public water systems: contaminants, monitoring, treatment technique, public notice, and related duties. State primacy agencies can be as strict or stricter. They cannot be weaker.
What we pull
- The current published text of 40 CFR Part 141 and related federal parts
- Which provisions apply given a system’s classification, population, and source water (those three sit on the PWSID record)
- Cross-checks against the system’s EPA violation history
We do not write the regulation. We point at it.
What we will not claim
- If we cannot point at the regulation, we do not say it.
- When the record cannot confirm something, the finding says Unable to Verify. That is not a violation.
- This is not legal advice. Verify with your primacy agency.
- Orevant does not submit records, tasks, findings, or applications to agencies.
