What Dothan's Water Means for Your Home
Hardness: 61 PPM - Low Concern
Dothan's water is moderately hard at 61 PPM. You'll see some spotting on glassware and a film on shower doors over time, but it's not the kind of hardness that demands a full softener. The minerals come from the local aquifer geology. A salt-free conditioner is worth considering if you have a tankless water heater or high-end fixtures.
Contaminants & Safety
Disinfection byproducts are the notable finding here. Dothan's water has TTHMs at 3.47 ppb and HAA5 at 0.967 ppb — both within legal limits, but the EWG health guidelines are far stricter. These byproducts form when chlorine reacts with organic matter during treatment. A whole-house activated carbon filter reduces both chlorine and its byproducts. Want the full picture? Request your utility's annual Consumer Confidence Report.
What's in the Treatment Process
Chromium-6 is naturally present in Dothan's aquifer geology at 0.0873 ppb — 4.4x 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 Dothan's Water Supply
Water Utility: Dothan Utilities
Water Source: Chattahoochee River Basin wells (Groundwater)
Population Served: 97,146
Hardness: 61 PPM (3.6 grains per gallon)
Dothan draws its drinking water from groundwater sources — Chattahoochee River Basin 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 97,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request Dothan Utilities's Consumer Confidence Report (CCR) or test your own tap.
