What Makes Moss Point's Water Unique?

Local geology and source profile

Source: GroundwaterTDS: 398 mg/LpH: 7.9

The City of Moss Point Water Department supplies about 13,000 people in Jackson County, Mississippi. Their water comes from several wells that tap into the Pascagoula River Alluvial Aquifer and the Catahoula Aquifer. These wells feed into the city's water treatment plant, where the groundwater is disinfected, mainly using chlorine. The treated water serves Moss Point and nearby unincorporated areas within Jackson County. The Moss Point supply originates in the Pascagoula River watershed, which is part of the larger Mobile River Basin that flows into the Gulf of Mexico.

The aquifers contain Tertiary sands and gravels from the Miocene Catahoula Formation. These are covered by Quaternary alluvial sediments that are rich in calcareous materials. This geological makeup causes minerals to dissolve naturally, giving the water a hard character with high levels of calcium and magnesium. These minerals significantly impact the water's overall chemistry and require special treatment approaches.

This very hard water in Moss Point can lead to considerable scale buildup in pipes, water heaters, dishwashers, and washing machines, which not only reduces efficiency but also shortens their lifespan. Homeowners often notice visible deposits on appliances like coffee makers and faucets, potentially increasing energy costs by as much as 20-30%. To combat this, regular maintenance such as vinegar descaling, installing scale inhibitors, and flushing systems annually is advised. A whole-house water softener is strongly recommended to prevent spotting on dishes and to improve skin and hair condition.

Frequently Asked Questions

Is Moss Point's water safe to drink?

Yes. Moss Point's water meets all federal safety standards. The hardness is ≈ 180+ mg/L (Very Hard), which is safe to drink. High hardness affects appliances and taste, but poses no health risk.

Do I need a water softener in Moss Point?

At ≈ 180+ mg/L (Very Hard), Moss Point's water will cause significant limescale on kettles, washing machines, and water heaters. A water softener or descaler is strongly recommended to extend appliance lifespan and reduce energy bills by up to 45%.

How does Moss Point compare to the USA average?

The USA national average is 151 mg/L. Moss Point (≈ 180+ mg/L) is 189 mg/L above the national average. The softest major city is Scarsdale at just 0.02 mg/L.

Data Sources & Methodology

Water quality data for Moss Point is derived from geographic and geological modelling of the surrounding region. No federal monitoring station data was available for this location.

Estimated

Water Hardness

Modelled estimate based on state-level USGS geological survey data for this region. No direct USGS Water Quality Portal measurement was matched to this city — the value reflects a statistical range calibrated to the state's dominant rock types and typical source water characteristics.

Estimated

Estimated from regional geology and source water characteristics. pH is correlated with water hardness and local bedrock — values may differ from utility-reported figures.

Estimated

TDS — Total Dissolved Solids

Estimated using a derived ratio from water hardness and regional conductance profiles. TDS in natural water correlates strongly with total mineral content including hardness ions.

Measured

PFAS — Perfluoroalkyl and Polyfluoroalkyl Substances

EPA UCMR5 (5th Unregulated Contaminant Monitoring Rule, 2023–2025) — sum of PFAS compounds detected at the public water system serving this city. A value of 0 indicates the system was sampled with no detection above reporting limits.

Modelled

Lead

Modelled estimate based on the EPA Lead and Copper Rule 90th-percentile tap-sample methodology. No publicly available per-city lead dataset with sufficient national coverage exists. Values are a conservative baseline derived from city population tier and infrastructure age — all estimates are maintained below the EPA action level of 0.015 mg/L.

Calculated

Appliance Lifespan

Calculated from water hardness using a linear degradation model. Baseline lifespans represent soft-water performance (kettle: 8.5 yrs, washing machine: 12.0 yrs, water heater: 15.0 yrs). Hard water mineral scale progressively reduces operational life in direct proportion to hardness concentration.
