After an Elburn water sample detected a PFAS “forever chemical” above state standards, officials quickly moved to retest the village’s drinking water.
Those tests have come back clean. No PFAS compounds were detected.
Following the detection of perfluorooctanoic acid (PFOA) in a December 2025 sample collected as part of the U.S. Environmental Protection Agency’s Unregulated Contaminant Monitoring Rule (UCMR) testing program, the Village conducted additional testing to further evaluate the water supply.
According to a news release, the Village used the same certified laboratory that performed the original testing. Two samples were collected and analyzed:
One sample from the Finished Tap, the same sampling location used during the U.S. EPA’s December testing.
One sample from the Raw Tap, which measures untreated water before it enters the treatment process. Sampling from the Raw Tap is not required by the U.S. EPA, but the Village included it to provide additional information about the water supply.
The village said both samples showed no detectable PFAS compounds.
Officials said they plan to share these results with the Illinois Environmental Protection Agency (IEPA) and will work with the agency to determine any appropriate next steps or follow-up actions.
The release also stated that the village will continue to take a proactive approach to water quality monitoring. Additional PFAS sampling will be conducted multiple times throughout the year to continue evaluating the water system and ensure ongoing safety.
