Is Goose Creek, SC Tap Water Safe to Drink?
Goose Creek tap water is legally compliant, but one contaminant exceeds health guidelines. Specifically: PFAS above EPA limits (PFOA: 4.7 ppt, PFOS: 4.9 ppt — limit is 4 ppt each). A point-of-use filter is recommended for drinking and cooking water.

How Goose Creek Compares
Goose Creek's water is 72% softer than the national average of 138 PPM - ranking in the bottom 77% for hardness nationwide. Most homes here do not need a softener. Within South Carolina, it ranks #9 of 16 cities (0% below the state average of 38 PPM). Among smaller cities, Goose Creek ranks #192 of 288 for hardness.
What Goose Creek's Water Means for Your Home
Hardness: 38 PPM - Low Concern
Goose Creek's water is slightly hard at 38 PPM. Most households won't notice any issues at this level. Scale buildup is minimal, and a water softener would be overkill. Goose Creek is softer than 77% of US cities. If you're thinking about water treatment, contaminant filtration is where to focus your money, not softening.
Contaminants & Safety
Forever chemicals (PFAS) are worth watching here. Goose Creek has PFOA at 4.7 ppt and PFOS at 4.9 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
Goose Creek's surface water supply requires heavy chlorination to stay safe — but that creates a tradeoff. The treatment process generates disinfection byproducts: TTHMs at 24.7 ppb (31% of the legal limit, but 165x the EWG guideline) and HAA5 at 11.7 ppb (19% of the legal limit, but 117x 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 0.0569 ppb, which is 2.8x 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) | 38 PPM | < 60 PPM | No federal limit | ✓ OK |
| Total Dissolved Solids | 56 PPM | < 300 PPM | 500 PPM | ✓ OK |
| PFAS (total) | 24.6 ppt | — | No total limit | Detected |
| ↳ PFOA | 4.7 ppt | 0 ppt | 4 ppt (2024) | ⚠ Exceeds |
| ↳ PFOS | 4.9 ppt | 0 ppt | 4 ppt (2024) | ⚠ Exceeds |
| Lead | 1.5 ppb | 0 ppb (no safe level) | 15 ppb (10 ppb in 2027) | ✓ Low |
| Chlorine / Chloramine | 0.5 mg/L | Taste threshold ~1.0 | 4.0 mg/L | ✓ Normal |
| Nitrate | 0.102 mg/L | 5 mg/L | 10 mg/L | ✓ OK |
Recommended Filter for Goose Creek
PFAS exceed EPA limits (PFOA: 4.7 ppt, PFOS: 4.9 ppt — limit: 4 ppt each). A certified filter reduces these contaminants effectively.

About Goose Creek's Water Supply
Water Utility: Berkeley County Water & Sanitation
Water Source: Edisto River (Surface Water)
Population Served: 40,628
Hardness: 38 PPM (2.2 grains per gallon)
Goose Creek's drinking water comes from surface sources — Edisto 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 41,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request Berkeley County Water & Sanitation's Consumer Confidence Report (CCR) or test your own tap.
