What Lacey's Water Means for Your Home
Hardness: 20 PPM - Low Concern
Lacey's water is slightly hard at 20 PPM. Most households won't notice any issues at this level. Scale buildup is minimal, and a water softener would be overkill. Lacey is softer than 92% of US cities. If you're thinking about water treatment, contaminant filtration is where to focus your money, not softening.
Contaminants & Safety
Lead levels deserve attention. At 6 ppb, Lacey is above the ideal of zero, though below the EPA action level of 15 ppb (dropping to 10 ppb in November 2027 under the Lead and Copper Rule Improvements). The lead typically comes from aging service lines or interior plumbing, not the treatment plant. A point-of-use filter certified for lead at the kitchen faucet is a practical safeguard, especially in older homes.
What's in the Treatment Process
Even though Lacey draws from groundwater, the treatment process still generates disinfection byproducts: TTHMs at 7.16 ppb and HAA5 at 8.6 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.
Chromium-6 is naturally present in Lacey's aquifer geology at 0.228 ppb — 11x the EWG health guideline. There's no federal legal limit for chromium-6 specifically (only total chromium), which is why EWG tracks it separately. 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) | 20 PPM | < 60 PPM | No federal limit | ✓ OK |
| Total Dissolved Solids | 33 PPM | < 300 PPM | 500 PPM | ✓ OK |
| PFAS (total) | 32.1 ppt | — | No total limit | Detected |
| ↳ PFOA | 0 ppt | 0 ppt | 4 ppt (2024) | ✓ OK |
| ↳ PFOS | 0 ppt | 0 ppt | 4 ppt (2024) | ✓ OK |
| Lead | 6 ppb | 0 ppb (no safe level) | 15 ppb (10 ppb in 2027) | ⚠ Elevated |
| Chlorine / Chloramine | 1.8 mg/L | Taste threshold ~1.0 | 4.0 mg/L | ✓ Normal |
| Nitrate | 1.72 mg/L | 5 mg/L | 10 mg/L | ✓ OK |
Recommendations for Lacey Homes
Quick Fix for Chlorine: Shower Filter
At 1.8 mg/L chlorine, many Lacey residents notice dry skin, brittle hair, and that "pool smell" in the shower. A shower filter installs in 5 minutes, no tools needed.
How to Test Your Water in Lacey
Lead enters water from your home's plumbing, not the treatment plant — so Lacey's city-wide average of 6 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 Lacey's Water Supply
Water Utility: City of Lacey Water
Water Source: McAllister Springs & wells (Groundwater)
Population Served: 103,755
Hardness: 20 PPM (1.2 grains per gallon)
Lacey draws its drinking water from groundwater sources — McAllister Springs & 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 104,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request City of Lacey Water's Consumer Confidence Report (CCR) or test your own tap.
