What Gulfport's Water Means for Your Home
Hardness: 107 PPM - Low Concern
Gulfport's water is firmly in the moderate range at 107 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. Gulfport's water has TTHMs at 14.1 ppb and HAA5 at 5.66 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
Even though Gulfport draws from groundwater, the treatment process still generates disinfection byproducts: TTHMs at 14.1 ppb and HAA5 at 5.66 ppb. Groundwater typically needs less treatment than surface water, but when organic compounds are present in the aquifer, chlorination creates the same byproducts. All levels are within legal limits, though above the stricter EWG health guidelines. All measurements are within federal legal limits. The EWG guidelines represent a more conservative, health-based standard.

Water Utility: City of Gulfport
Water Source: Deep wells (Groundwater)
Population Served: 75,056
Hardness: 107 PPM (6.3 grains per gallon)
Gulfport draws its drinking water from groundwater sources — Deep 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 75,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request City of Gulfport's Consumer Confidence Report (CCR) or test your own tap.
