North Smithfield's middle and high school campus may not get its permanent PFAS treatment system by the Feb. 15, 2027 date in the corrective action plan. The engineer overseeing the project, Bob Ferrari, told the School Committee that final state approval and a public bid are still ahead, and summer construction may be more practical than the current target. The design uses three carbon filtration vessels in series, with the lead vessel capped at 130 days because the water also contains radon. Until the system is installed, the campus will keep blending water from its two wells to stay below the state limit of 20 parts per trillion. The project is funded with federal money through a state program, and the next step is a decision from the Rhode Island Department of Health.
