What Pawtucket's Water Means for Your Home
Hardness: 24 PPM - Low Concern
Pawtucket's water is slightly hard at 24 PPM. Most households won't notice any issues at this level. Scale buildup is minimal, and a water softener would be overkill. Pawtucket is softer than 89% of US cities. If you're thinking about water treatment, contaminant filtration is where to focus your money, not softening.
Contaminants & Safety
Disinfection byproducts are the notable finding here. Pawtucket's water has TTHMs at 36.1 ppb and HAA5 at 20.4 ppb — both within legal limits, but the EWG health guidelines are far stricter. These byproducts form when chlorine reacts with organic matter during treatment. A whole-house activated carbon filter reduces both chlorine and its byproducts. Want the full picture?

What's in the Treatment Process
Pawtucket's surface water supply requires heavy chlorination to stay safe — but that creates a tradeoff. The treatment process generates disinfection byproducts: TTHMs at 36.1 ppb (45% of the legal limit, but 241x the EWG guideline) and HAA5 at 20.4 ppb (34% of the legal limit, but 204x the EWG guideline). These are within legal limits, but the EWG sets much tighter thresholds based on cancer-risk research. A whole-house activated carbon filter reduces both chlorine and byproducts.
Chromium-6 was detected at 0.0804 ppb, which is 4x the EWG health guideline. There's no separate federal limit for chromium-6, only total chromium. A reverse osmosis system is the most effective removal method. All measurements are within federal legal limits. The EWG guidelines represent a more conservative, health-based standard.

About Pawtucket's Water Supply
Water Utility: Providence Water
Water Source: Scituate Reservoir via Providence (Surface Water)
Population Served: 98,130
Hardness: 24 PPM (1.4 grains per gallon)
Pawtucket's drinking water comes from surface sources — Scituate Reservoir via Providence. Surface water requires more extensive treatment than groundwater, including coagulation, filtration, and disinfection. This heavier chlorination is why disinfection byproducts tend to be higher in surface-supplied systems. On the upside, surface sources often deliver softer water than deep aquifers. The system serves 98,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request Providence Water's Consumer Confidence Report (CCR) or test your own tap.
