Is Sandy, OR Tap Water Safe to Drink?
Sandy tap water is legally compliant, but one contaminant exceeds health guidelines. Specifically: lead at 13 ppb (above the upcoming 10 ppb standard, effective 2027). A point-of-use filter is recommended for drinking and cooking water.

How Sandy Compares
Sandy's water is 90% softer than the national average of 138 PPM - ranking in the bottom 99% for hardness nationwide. Most homes here do not need a softener. Within Oregon, it ranks #47 of 48 cities (44% below the state average of 25 PPM). Among smaller cities, Sandy ranks #281 of 288 for hardness.
What Sandy's Water Means for Your Home
Hardness: 14 PPM - Low Concern
Sandy's water is soft at just 14 PPM. That's good news for your plumbing, appliances, and skin. Scale buildup is a non-issue here, and a water softener would be a waste of money. Sandy is softer than 99% of US cities. If you're thinking about water treatment in Sandy, contaminant filtration is the place to invest.
Contaminants & Safety
Lead is the main concern here. At 13 ppb, Sandy's average is well above the health guideline of zero — there is no safe level of lead, especially for children. Lead typically enters your water from old pipes, not the source itself. Quick fix: run cold water for 30 seconds before drinking. Better fix: a certified lead-reduction filter (NSF/ANSI Standard 53) at your kitchen faucet. If your home was built before 1986, testing is strongly recommended.
What's in the Treatment Process
Sandy's surface water supply requires heavy chlorination to stay safe — but that creates a tradeoff. The treatment process generates disinfection byproducts: TTHMs at 39.3 ppb (49% of the legal limit, but 262x the EWG guideline) and HAA5 at 45.4 ppb (76% of the legal limit, but 454x 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) | 14 PPM | < 60 PPM | No federal limit | ✓ OK |
| Total Dissolved Solids | 23 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 | 13 ppb | 0 ppb (no safe level) | 15 ppb (10 ppb in 2027) | ⚠ Elevated |
| Chlorine / Chloramine | 0.9 mg/L | Taste threshold ~1.0 | 4.0 mg/L | ✓ Normal |
| Nitrate | 0.0728 mg/L | 5 mg/L | 10 mg/L | ✓ OK |
Recommended Filter for Sandy
Lead at 13 ppb exceeds the upcoming 10 ppb action level (effective 2027). A certified filter reduces these contaminants effectively.
How to Test Your Water in Sandy
Lead enters water from your home's plumbing, not the treatment plant — so Sandy's city-wide average of 13 ppb may not match your tap. Testing your specific faucet is the only way to know. Run cold water for 30 seconds before collecting a sample.

About Sandy's Water Supply
Water Utility: City of Sandy Water
Water Source: local springs & wells near Mt. Hood (Surface Water)
Population Served: 12,991
Hardness: 14 PPM (0.8 grains per gallon)
Sandy's drinking water comes from surface sources — local springs & wells near Mt. Hood. 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 City of Sandy Water's Consumer Confidence Report (CCR) or test your own tap.
