What Roseburg's Water Means for Your Home
Hardness: 22 PPM - Low Concern
Roseburg's water is slightly hard at 22 PPM. Most households won't notice any issues at this level. Scale buildup is minimal, and a water softener would be overkill. Roseburg is softer than 91% 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. Roseburg's water has TTHMs at 23.9 ppb and HAA5 at 22.1 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
Roseburg's surface water supply requires heavy chlorination to stay safe — but that creates a tradeoff. The treatment process generates disinfection byproducts: TTHMs at 23.9 ppb (30% of the legal limit, but 159x the EWG guideline) and HAA5 at 22.1 ppb (37% of the legal limit, but 221x 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 0.102 ppb, which is 5.1x 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.
| Contaminant | Detected | Health Guideline | Legal Limit | Status |
|---|---|---|---|---|
| Hardness (as CaCO₃) | 22 PPM | < 60 PPM | No federal limit | ✓ OK |
| Total Dissolved Solids | 32 PPM | < 300 PPM | 500 PPM | ✓ OK |
| PFAS (total) | 0 ppt | — | No total limit | ✓ ND |

Good news for Roseburg 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 Roseburg's Water Supply
Water Utility: City of Roseburg Water
Water Source: North Umpqua River (Surface Water)
Population Served: 28,800
Hardness: 22 PPM (1.3 grains per gallon)
Roseburg's drinking water comes from surface sources — North Umpqua 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 29,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request City of Roseburg Water's Consumer Confidence Report (CCR) or test your own tap.
