What Stafford's Water Means for Your Home
Hardness: 100 PPM - Low Concern
Stafford's water is firmly in the moderate range at 100 PPM. You'll see some spotting on glassware and a film on shower doors over time, but it's not the kind of hardness that demands a full softener. A salt-free conditioner is worth considering if you have a tankless water heater or high-end fixtures.
Contaminants & Safety
Forever chemicals (PFAS) are worth watching here. Stafford has PFOS at 5.23 ppt, exceeding the EPA's 2024 limit of 4 ppt per compound. PFAS are synthetic compounds that accumulate in your body over time. A certified carbon filter or reverse osmosis system with NSF P473 certification is the most effective protection. See the regulatory timeline.
What's in the Treatment Process
Stafford's surface water supply requires heavy chlorination to stay safe — but that creates a tradeoff. The treatment process generates disinfection byproducts: TTHMs at 34.2 ppb (43% of the legal limit, but 228x the EWG guideline) and HAA5 at 21.2 ppb (35% of the legal limit, but 212x 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.
| Contaminant | Detected | Health Guideline | Legal Limit | Status |
|---|---|---|---|---|
| Hardness (as CaCO₃) | 100 PPM | < 60 PPM | No federal limit | ✓ OK |
| Total Dissolved Solids | 170 PPM | < 300 PPM | 500 PPM | ✓ OK |
| PFAS (total) | 11.23 ppt | — | No total limit | Detected |
| ↳ PFOA | 0 ppt | 0 ppt | 4 ppt (2024) | ✓ OK |
| ↳ PFOS | 5.23 ppt | 0 ppt | 4 ppt (2024) | ⚠ Exceeds |
| Lead | 1.8 ppb | 0 ppb (no safe level) | 15 ppb (10 ppb in 2027) | ✓ Low |
| Chlorine / Chloramine | 1.3 mg/L | Taste threshold ~1.0 | 4.0 mg/L | ✓ Normal |

About Stafford's Water Supply
Water Utility: Stafford County Water
Water Source: Aquia Creek + Potomac (Surface Water)
Population Served: 123,684
Hardness: 100 PPM (5.8 grains per gallon)
Stafford's drinking water comes from surface sources — Aquia Creek + Potomac. 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 124,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request Stafford County Water's Consumer Confidence Report (CCR) or test your own tap.
