Questions
Does Rhode Island tap water have PFAS?
In EPA's UCMR 5 testing, 15 of 29 Rhode Island water systems (52%) had at least one PFAS compound detected, and 11 had PFOA or PFOS above EPA's 4 ppt limit.
What is the best water filter in Rhode Island?
It depends on your utility. Where PFAS is above EPA's limit, reverse osmosis is the most effective option. Where the main concern is lead from home plumbing or chlorine taste, a certified carbon filter is enough. Enter your address to get a match.
