Routine federal monitoring and contaminant testing shown elsewhere on this page determine whether the water meets safety standards, not the treatment classification.
Federal UCMR5 PFAS Monitoring: Tested Clean
This water system was tested under the federal EPA Unregulated Contaminant Monitoring Rule (UCMR5). No PFAS compounds were detected.
Current MCL reflects the lowest state-enforceable limit (NYS 10 ppt for PFOA/PFOS, effective August 2020). The federal final MCL of 4 ppt for PFOA/PFOS (EPA April 2024 rule) is not enforceable until April 2029. Detections above 4 ppt but below 10 ppt are below current MCL but above the future federal limit.

The City of Fargo is developing a Lead Service Line Replacement Program, set to begin in the summer of 2025. This program is designed to be affordable by using state and federal funding, along with a City utility cost-share program. This means no added costs will be charged, provided property owners complete required water sampling three to six months after replacement. Failure to fulfill the sampling requirement after replacement will void the agreement to replace your lead service line and a $1,000 invoice will be billed to the property owner.
