Lead Service Line Compliance in North Dakota
Current status
As of October 2024, North Dakota's 399 public water systems serving 712,514 people reported their lead service line inventories to the EPA under the Lead and Copper Rule Revisions (LCRR). The state's utilities reported 0 known lead service lines and 0 unknown service lines across all systems combined.
This result is unusual and warrants context. North Dakota's inventory data suggests either that lead service lines are genuinely absent from the state's water infrastructure, or that systems have not yet fully investigated their pipe materials. The LCRR requires utilities to identify service lines by type—copper, galvanized steel, lead, or unknown—by systematically reviewing records, excavating samples, or using other verification methods. A zero count for both known and unknown categories suggests reporting may still be in progress at some utilities.
What the LCRR requires
The EPA's Lead and Copper Rule Revisions, finalized in 2021, require all water systems to:
- Complete a full inventory of service line materials by October 2024
- Report results to state primacy agencies
- Begin replacing lead service lines if any are found
- Provide notice to customers about lead risks and their service line status
North Dakota's Department of Environmental Quality oversees water quality standards and LCRR compliance for the state's public water systems.
What zero inventories might mean
A reported zero-zero count could indicate:
- Genuine absence: Some regions have primarily copper or galvanized infrastructure installed after lead fell out of common use (late 1980s onward).
- Ongoing investigation: Utilities may still be validating records or conducting sampling and have not finalized counts.
- Incomplete reporting: Some smaller systems may not have submitted verified data by the October deadline.
If you're concerned about your specific water system, contact your local utility directly. They can tell you whether your service line has been tested and what material feeds your home.
Next steps for residents
- Contact your water utility and ask for your service line material status. Request a copy of their LCRR inventory if available.
- Check your water bill or utility website for lead and copper test results and public notices.
- If your service line is lead or unknown, ask about replacement programs and EPA guidance on interim protection (flushing, filters).
- For health concerns, consult the CDC's lead exposure guidance or speak with your pediatrician.
