What Wilkes-Barre South's Water Means for Your Home
Hardness: 50 PPM - Low Concern
Wilkes-Barre South's water is slightly hard at 50 PPM. Most households won't notice any issues at this level. Scale buildup is minimal, and a water softener would be overkill. 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. Wilkes-Barre South's water has TTHMs at 42.3 ppb and HAA5 at 34.8 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
Wilkes-Barre South's surface water supply requires heavy chlorination to stay safe — but that creates a tradeoff. The treatment process generates disinfection byproducts: TTHMs at 42.3 ppb (53% of the legal limit, but 282x the EWG guideline) and HAA5 at 34.8 ppb (58% of the legal limit, but 348x 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. All measurements are within federal legal limits. The EWG guidelines represent a more conservative, health-based standard.

|---|---|---|---|---|
| Hardness (as CaCO₃) | 50 PPM | < 60 PPM | No federal limit | ✓ OK |
| Total Dissolved Solids | 90 PPM | < 300 PPM | 500 PPM | ✓ OK |
| PFAS (total) | 0 ppt | — | No total limit | ✓ ND |
| ↳ PFOA | 0 ppt | 0 ppt | 4 ppt (2024) | ✓ OK |
| ↳ PFOS | 0 ppt | 0 ppt | 4 ppt (2024) | ✓ OK |
| Lead | 3 ppb | 0 ppb (no safe level) | 15 ppb (10 ppb in 2027) | ✓ Low |

Good news for Wilkes-Barre South residents. Your water quality is generally good. Most homes in this area do not need a water softener.

Quick Fix for Chlorine: Shower Filter
At 1.2 mg/L chlorine, many Wilkes-Barre South residents notice dry skin, brittle hair, and that "pool smell" in the shower. A shower filter installs in 5 minutes, no tools needed.

About Wilkes-Barre South's Water Supply
Water Utility: PA American Water
Water Source: Susquehanna River (Surface Water)
Population Served: 12,560
Hardness: 50 PPM (2.9 grains per gallon)
Wilkes-Barre South's drinking water comes from surface sources — Susquehanna River. 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 13,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request PA American Water's Consumer Confidence Report (CCR) or test your own tap.
