What Olive Branch's Water Means for Your Home
Hardness: 50 PPM - Low Concern
Olive Branch's water is slightly hard at 50 PPM. Most households won't notice any issues at this level. Scale buildup is minimal, and a water softener would be overkill. If you're thinking about water treatment, contaminant filtration is where to focus your money, not softening.
Contaminants & Safety
Beyond hardness, Olive Branch's water is within EPA guidelines for regulated contaminants. Chlorine sits at 1.4 mg/L — normal for municipal systems, but enough to notice. That said, 6 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 Olive Branch's aquifer geology at 0.0441 ppb — 2.2x 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 Olive Branch's Water Supply

Water Source: Memphis Sand Aquifer (Groundwater)
Population Served: 54,025
Hardness: 50 PPM (2.9 grains per gallon)
Olive Branch draws its drinking water from groundwater sources — Memphis Sand 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 54,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request City of Olive Branch Water's Consumer Confidence Report (CCR) or test your own tap.
