What Hicksville's Water Means for Your Home
Hardness: 40 PPM - Low Concern
Hicksville's water is slightly hard at 40 PPM. Most households won't notice any issues at this level. Scale buildup is minimal, and a water softener would be overkill. Hicksville is softer than 76% of US cities. If you're thinking about water treatment, contaminant filtration is where to focus your money, not softening.
Contaminants & Safety
Beyond hardness, Hicksville's water is within EPA guidelines for regulated contaminants. Chlorine sits at 1.1 mg/L — normal for municipal systems, but enough to notice. That said, 10 contaminants exceed EWG's stricter health guidelines — these are legal but worth understanding. 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.
What's in the Treatment Process
Chromium-6 is naturally present in Hicksville's aquifer geology at 0.476 ppb — 24x 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.

About Hicksville's Water Supply
Water Utility: Hicksville Water District
Water Source: Long Island Aquifer (Groundwater)
Population Served: 48,000
Hardness: 40 PPM (2.3 grains per gallon)
Hicksville draws its drinking water from groundwater sources — Long Island Aquifer. 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 48,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request Hicksville Water District's Consumer Confidence Report (CCR) or test your own tap.
