The Story

The city is running PFOS/PFOA wastewater sampling required by its state discharge permit, with results due in July. Staff said the numbers they’re seeing are around 126 versus an anticipated limit of 140, and they expect the landfill to test high enough to be a major source. Depending on the final results, the city may have to write a PFAS minimization plan.
