Serving Rhode Island & Southeastern Massachusetts
BCWA supplies Barrington, Bristol and Warren. Since 2011, its sole source has been the Scituate Reservoir system treated by Providence Water and delivered through the East Bay Pipeline. BCWA's 2025 report says the system did not exceed any water-quality regulations during the year. Because the Scituate Reservoir is a surface-water source, treatment focuses on filtration and disinfection rather than removing the naturally occurring hardness minerals more typical of well water in the region.
BCWA reported 65.7 ppb TTHMs, 17.6 ppb HAA5, 0.51 ppm chlorine, a 1.90 ppb lead 90th percentile, and no detection for Rhode Island's six-compound PFAS total. These are system-level results, not a substitute for testing a specific home when plumbing or drinking-water concerns are involved. For scale, the EPA's limits are 80 ppb for TTHMs, 60 ppb for HAA5 and 4 ppm for chlorine, and Rhode Island's PFAS6 standard is 20 ppt. BCWA's chlorine and HAA5 results sit comfortably below their limits and PFAS6 wasn't detected at all; the 65.7 ppb TTHM result is somewhat closer to its 80 ppb limit than the rest, though still fully compliant.
BCWA reported a 2025 lead 90th percentile of 1.90 ppb with 0 of 30 sites above the 15 ppb action level. BCWA also notes that lead in drinking water is primarily associated with service lines and home plumbing materials, so an individual home can still warrant tap-specific testing even when utility results are low. Homes built before 1986, when lead solder and lead service lines were more common, are the properties where this distinction matters most.
BCWA's 2025 report lists the Rhode Island six-PFAS total as not detected and also says its UCMR5 samples for 29 PFAS compounds were below the minimum reporting level. That is strong utility-level context, but treatment decisions for a particular home should still be based on the homeowner's concern and, when needed, appropriate certified testing. A clean utility-wide result also doesn't rule out contamination from a source specific to one property, such as older fire-fighting foam use or nearby industrial activity.
Whole-home carbon can be a strong option when testing and homeowner goals point to chlorine-related taste and odor or certain disinfection byproducts. The right system depends on flow rate, contact time and the conditions at the home, which is why AquaTrust tests before sizing equipment.
Under-sink reverse osmosis treats water at the point of use and can be a strong fit for homeowners who want an additional drinking-water barrier without treating every gallon used for showers, laundry and irrigation.
If lead is a concern, test at the tap because household plumbing and service-line materials can affect the result. Treatment should use equipment specifically certified for lead reduction and should not be used as a substitute for correcting a lead-containing service line or plumbing source when replacement is possible. Point-of-use filters certified under NSF/ANSI Standard 53 for lead reduction are the relevant category to look for.
Yes. BCWA's public report does not provide a house-specific hardness result, and a utility report cannot tell us exactly what is happening at your faucet. AquaTrust measures the water at the home so we can confirm hardness and other treatment conditions before recommending equipment. If the water does not support a softener, we will say so—and if another treatment makes more sense, we will show you why. Barrington doesn't have a significant private-well population, but that doesn't mean every home's plumbing behaves the same way BCWA's town-wide average suggests.
Your results drive the recommendation. We explain what matters, what does not, and what—if anything—is worth treating.
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.
