What Brookhaven's Water Means for Your Home
Hardness: 34 PPM - Low Concern
Brookhaven's water is slightly hard at 34 PPM. Most households won't notice any issues at this level. Scale buildup is minimal, and a water softener would be overkill. Brookhaven is softer than 80% of US cities. If you're thinking about water treatment, contaminant filtration is where to focus your money, not softening.
Contaminants & Safety
Beyond hardness, Brookhaven's water is within EPA guidelines for regulated contaminants. Chlorine sits at 1.2 mg/L — normal for municipal systems, but enough to notice. 1 contaminant exceeds EWG's stricter health guidelines, though all are within legal limits. If your water tastes like a pool or your skin feels dry after showers, a whole-house carbon filter is the simplest fix. A shower filter is a quick, affordable starting point that most people notice immediately. Want the full picture? Request your utility's annual Consumer Confidence Report for neighborhood-level data.

About Brookhaven's Water Supply
Water Utility: DeKalb County Water
Water Source: Chattahoochee River (Groundwater)
Population Served: 156
Hardness: 34 PPM (2 grains per gallon)
Brookhaven draws its drinking water from groundwater sources — Chattahoochee River. 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 156 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request DeKalb County Water's Consumer Confidence Report (CCR) or test your own tap.
