What Makes Conway's Water Unique?

Local geology and source profile

Source: GroundwaterTDS: 342.3 mg/LpH: 7.8

Conway, Florida's municipal water originates from the Floridan Aquifer System, tapped through numerous wellfields by providers like Jacksonville Electric Authority (JEA) and Orange County Utilities. Treatment occurs at facilities such as the JEA's water treatment plants, where disinfection, filtration, and basic conditioning processes are applied before the water reaches residents in the suburban communities surrounding Lake Conway, southeast of Orlando. This extensive aquifer system, a primary source for Central Florida, draws from a watershed that is part of the Upper Floridan Aquifer recharge area, with drainage patterns influenced by the St. Johns River basin.

Geologically, Conway's water is drawn from deep within the Floridan Aquifer System, interacting with thick layers of Paleogene limestone. Key formations include the karstic Ocala Limestone and the Avon Park Formation. These highly permeable limestone rocks are rich in calcium carbonate. As groundwater slowly percolates through these formations, it dissolves these minerals, leading to naturally high concentrations of calcium and magnesium. This process imbues the water with its characteristic hardness, a common trait in regions with this specific geology.

Homeowners in Conway will likely notice the effects of this hard water on their appliances and plumbing. Scale buildup is a frequent issue, forming on fixtures and inside water heaters, dishwashers, and coffee makers, which can reduce their efficiency and lifespan. You might also find soap scum in showers and spots on glassware after washing. Regular descaling with vinegar can help, and using rinse aids in your dishwasher is beneficial. To truly combat the effects and protect your plumbing, installing a whole-home water softener is often recommended. While the water meets federal standards, some contaminants have been detected above EPA health guidelines, so vulnerable populations may wish to use certified filters.

Geology & Source: Floridan Aquifer System - Eocene/Oligocene carbonate rocks; highly permeable limestone rich in calcium carbonate causes high hardness

Frequently Asked Questions

Is Conway's water safe to drink?
Yes. Conway'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 Conway?
At ≈ 120–179 mg/L (Hard), Conway'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 Conway compare to the USA average?
The USA national average is 151 mg/L. Conway (≈ 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 Conway 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

pH

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.
