Serving Rhode Island & Southeastern Massachusetts
NTFD purchases treated water from the City of Fall River and Stone Bridge Fire District. Fall River water comes from the Watuppa Reservoir system; Stone Bridge draws from Stafford Pond. The 2024 data reported a PFAS6 result of 4.3 ng/L in the Fall River supply, below the then-listed 20 ng/L Massachusetts PFAS6 standard.
Private-well water is the homeowner's responsibility to test. RIDOH recommends annual testing for coliform bacteria, nitrate/nitrite, color, chloride, sodium and turbidity; every 3–5 years for metals, corrosivity and hardness; and every 5–10 years for VOCs and MTBE. Private wells are common in Tiverton and across Rhode Island — nationally, the EPA estimates more than 23 million households, about 15% of the U.S. population, get their drinking water from a private well, and none of those wells are covered by any utility report or regulated the way a public water system is.
The NTFD report listed a 90th-percentile lead result of 1 ppb for its 2021–2023 monitoring period, below the 15 ppb action level shown in the report. It also reported total trihalomethane and haloacetic-acid monitoring results, reminding homeowners that utility data and conditions at an individual tap are not exactly the same thing. For reference, the EPA's national limits for these disinfection byproducts are 80 ppb for TTHMs and 60 ppb for HAA5, with a chlorine residual limit of 4 ppm — figures worth having on hand if you want to compare NTFD's full report against a federal benchmark.
RIDOH maintains a Tiverton-specific private-well PFAS FAQ, while the NTFD report also includes PFAS results from its purchased supplies. Public-water data can provide context, but a private well requires property-specific testing to determine whether PFAS are present. Rhode Island's current PFAS6 standard for public water systems is 20 parts per trillion; there's no equivalent automatic testing requirement for a private well, which is why RIDOH's guidance points well owners toward voluntary certified testing rather than a compliance report.
For public-water homes, activated carbon may be considered for chlorine-related taste and odor or certain organic compounds, depending on the homeowner’s goal and the water profile. It should not be marketed as a universal solution for every contaminant.
Private wells may require softening, iron or manganese filtration, low-pH neutralization, sulfur treatment, sediment control or other targeted equipment. Testing determines the correct order and sizing.
Under-sink reverse osmosis provides point-of-use drinking-water treatment. It can complement whole-home filtration when a homeowner wants separate treatment at the kitchen tap.
PFAS treatment should be based on certified laboratory results, not taste or smell. Appropriate point-of-use or point-of-entry treatment may include reverse osmosis or qualifying adsorptive media, followed by verification testing to confirm performance. Whichever method is used, retesting after installation is the only way to confirm the system is actually holding PFAS below Rhode Island's 20 ppt standard over time, not just on day one.
Clear recommendations with no franchise-style pressure, locked-in rental plan, or hidden maintenance surprises.
Local water context is useful, but treatment decisions should follow the actual condition at the home. These pages connect common homeowner concerns to the right next step.
Tiverton includes public-water customers and private-well homes, so there is no single “Tiverton water” profile. North Tiverton Fire District purchases treated water from the City of Fall River and Stone Bridge Fire District, while other Tiverton properties use private wells.

NTFD reports that it purchases treated drinking water from Fall River and Stone Bridge Fire District. Fall River water originates in the Watuppa Reservoir system, while Stone Bridge uses Stafford Pond. The utility’s 2024 data gives Tiverton homeowners a useful public-water baseline before considering home treatment.
Stone Bridge Fire District supplies part of Tiverton, while many other homes use private wells. RIDOH maintains separate private-well testing guidance, so identifying the water source at the property comes before treatment recommendations.
The 2024 monitoring data in NTFD’s 2025 report includes PFAS, lead and copper, disinfection byproducts, sodium, manganese, nitrate, pH and other regulated or monitored parameters. The report lists PFAS6 at 4.3 ng/L in the Fall River supply, average pH of 7.71, manganese at 0.016 ppm and a 90th-percentile lead result of 1 ppb for the 2021–2023 monitoring period.

That does not mean every homeowner needs additional equipment. Public-system treatment, household plumbing, taste and odor goals, hardness, and drinking-water preferences are separate questions.

Do not choose equipment from the ZIP code alone. Tiverton is exactly the kind of community where utility boundaries and private wells make address-level source identification essential.
