What Newberg's Water Means for Your Home
Hardness: 24 PPM - Low Concern
Newberg'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. Newberg 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. Newberg's water has TTHMs at 32.5 ppb and HAA5 at 7.83 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? Request your utility's annual Consumer Confidence Report.
What's in the Treatment Process
Even though Newberg draws from groundwater, the treatment process still generates disinfection byproducts: TTHMs at 32.5 ppb and HAA5 at 7.83 ppb. Groundwater typically needs less treatment than surface water, but when organic compounds are present in the aquifer, chlorination creates the same byproducts. All levels are within legal limits, though above the stricter EWG health guidelines. All measurements are within federal legal limits. The EWG guidelines represent a more conservative, health-based standard.
| Contaminant | Detected | Health Guideline | Legal Limit | Status |
|---|---|---|---|---|
| Hardness (as CaCO₃) | 24 PPM | < 60 PPM | No federal limit | ✓ OK |
| Total Dissolved Solids | 38 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 | 2.3 ppb | 0 ppb (no safe level) | 15 ppb (10 ppb in 2027) | ✓ Low |
| Chlorine / Chloramine | 0.8 mg/L | Taste threshold ~1.0 | 4.0 mg/L | ✓ Normal |
| Nitrate | 0.0733 mg/L | 5 mg/L | 10 mg/L | ✓ OK |
Good news for Newberg residents. Your water quality is generally good. Most homes in this area do not need a water softener. If you have concerns about lead (especially in buildings constructed before 1986) or chlorine taste, a point-of-use filter is the most practical and cost-effective solution.

About Newberg's Water Supply
Water Utility: City of Newberg Water
Water Source: Willamette River & wells (Groundwater)
Population Served: 25,138
Hardness: 24 PPM (1.4 grains per gallon)
Newberg draws its drinking water from groundwater sources — Willamette River & wells. Groundwater typically requires less treatment than surface water because the earth acts as a natural filter. The tradeoff: dissolved minerals from underground rock formations, which is why mineral content varies by aquifer depth and geology. The geological profile determines hardness, iron, and trace mineral levels. The system serves 25,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request City of Newberg Water's Consumer Confidence Report (CCR) or test your own tap.
