What Pearl's Water Means for Your Home
Hardness: 55 PPM - Low Concern
Pearl's water is slightly hard at 55 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
Disinfection byproducts are the notable finding here. Pearl's water has TTHMs at 23.1 ppb and HAA5 at 11.7 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 Pearl draws from groundwater, the treatment process still generates disinfection byproducts: TTHMs at 23.1 ppb and HAA5 at 11.7 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.

About Pearl's Water Supply
Water Utility: City of Pearl Water
Water Source: Ross Barnett Reservoir (Groundwater)
Population Served: 27,115
Hardness: 55 PPM (3.2 grains per gallon)
Pearl draws its drinking water from groundwater sources — Ross Barnett Reservoir. 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 27,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request City of Pearl Water's Consumer Confidence Report (CCR) or test your own tap.
