North Smithfield School PFAS Filter Update: Carbon Treatment, Timeline, and Funding

North Smithfield school officials got an update on a planned PFAS carbon filtration system for the middle and high school wells. The design uses three carbon filters in series inside the existing pump house and is funded by a $674,000 federal grant. The corrective action plan sets a Feb. 15, 2027 installation date, but the engineer said public bidding could push that timeline. The campus has blended water from two wells since 2023 to stay under Rhode Island's 20 ppt PFAS limit. Well number two has measured between 30 and 60 ppt, with one reading over 80. The new system is designed to reach non-detectable levels for six regulated PFAS compounds. The source of the contamination remains unknown. The engineer said it is probable the school's leach field is influencing well number two, but no downhole camera survey or pump testing has been done. Private well tests for nearby residents now cost about $200 through the state monitoring program.

Good writeup. The interesting part is the $674k federal grant covers the whole campus treatment system. That's real money going to a concrete fix. Still no confirmed source for the PFAS, which matters because the school can filter its own wells while neighbors are left paying $200 for a test.

The 130 day cap on the lead filter is a nice detail. They're swapping media based on radon buildup, not just PFAS breakthrough. That's the kind of operational cost people ignore when they talk about carbon filtration. The Feb 2027 date slipping is almost expected once public bidding gets involved.

Do we know if the design accounts for the full lifecycle cost of media replacement? Three filters in series with a 130 day cap on the lead means frequent media swaps. That's recurring expense and disposal logistics, not a one time grant. Would be good to see the operations budget.

Worth noting the source question is still open. The engineer thinks the leach field is probable but no downhole camera or pump test has been done. The turf field gets mentioned because of crumb rubber, but he didn't rule it in or out. That's the part that needs more study.
