What Brooklyn's Water Means for Your Home
Hardness: 25 PPM - Low Concern
Brooklyn's water is slightly hard at 25 PPM. Most households won't notice any issues at this level. Scale buildup is minimal, and a water softener would be overkill. Brooklyn is softer than 88% 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 6.1 ppb, Brooklyn 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.
| Contaminant | Detected | Health Guideline | Legal Limit | Status |
|---|---|---|---|---|
| Hardness (as CaCO₃) | 25 PPM | < 60 PPM | No federal limit | ✓ OK |
| Total Dissolved Solids | 45 PPM | < 300 PPM | 500 PPM | ✓ OK |
| PFAS (total) | Not tested | — | No total limit | N/A |
| Lead | 6.1 ppb | 0 ppb (no safe level) | 15 ppb (10 ppb in 2027) | ⚠ Elevated |
| Chlorine / Chloramine | 1.5 mg/L | Taste threshold ~1.0 | 4.0 mg/L | ✓ Normal |
| Nitrate | 0.29 mg/L | 5 mg/L | 10 mg/L | ✓ OK |
Quick Fix for Chlorine: Shower Filter
At 1.5 mg/L chlorine, many Brooklyn 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 Brooklyn
Lead enters water from your home's plumbing, not the treatment plant — so Brooklyn's city-wide average of 6.1 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 Brooklyn's Water Supply
Water Utility: NYC DEP
Water Source: Surface water (reservoirs) (Groundwater)
Population Served: 285
Hardness: 25 PPM (1.5 grains per gallon)
Brooklyn draws its drinking water from groundwater sources — Surface water (reservoirs). 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 285 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request NYC DEP's Consumer Confidence Report (CCR) or test your own tap.
