What Makes Marlton's Water Unique?

Local geology and source profile

Source: ReservoirTDS: 159 mg/LpH: 7

Marlton, New Jersey, located in Burlington County, receives its water from the Evesham Municipal Utilities Authority (EMUA). This utility serves an estimated 45,538 residents, managing both water treatment and distribution. The primary source of Marlton's water is the New Jersey Coastal Plain aquifer system, a crucial underground resource for the region. For service inquiries, residents can reach the EMUA at 856-983-1878 (ext. 107).

The New Jersey Coastal Plain aquifer system is geologically characterized by unconsolidated sediments from the Cretaceous and Tertiary periods, including sands, silts, and clays. These layers sit atop older Precambrian crystalline bedrock. As groundwater percolates through these formations, it naturally picks up dissolved minerals like calcium and magnesium. This process is typical for the area and results in a consistently hard water supply for Marlton.

Homeowners in Marlton might notice scale buildup in appliances like water heaters and kettles, and potentially reduced lathering from soaps and detergents. Over time, this hardness can affect the efficiency of dishwashers and washing machines. Installing a water softener is often recommended to combat these issues, especially for households with high water usage. The Evesham MUA monitors its supply to meet state and federal standards, though residents should review the utility's Consumer Confidence Report for specific details on tested contaminants and water quality parameters.

Frequently Asked Questions

Is Marlton's water safe to drink?

Yes. Marlton's water meets all federal safety standards. The hardness is ≈ 120–179 mg/L (Hard), which is safe to drink. High hardness affects appliances and taste, but poses no health risk.

Do I need a water softener in Marlton?

At ≈ 120–179 mg/L (Hard), Marlton'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 20%.

How does Marlton compare to the USA average?

The USA national average is 151 mg/L. Marlton (≈ 120–179 mg/L) is 1 mg/L below the national average. The softest major city is Scarsdale at just 0.02 mg/L.

Data Sources & Methodology

Water quality data for Marlton 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.
