What Makes Holly Hill's Water Unique?

Local geology and source profile

Source: GroundwaterTDS: 177.1 mg/LpH: 7.4

The City of Holly Hill Water Company provides drinking water to about 13,832 residents in Holly Hill, Florida. Their sole water source is groundwater, drawn from wells that tap into the Floridan aquifer. This water is treated at a facility located at 453 LPGA Blvd, Holly Hill, FL 32117. The Holly Hill system, which operates within the St. Johns River Water Management District watershed, consistently delivers treated water that meets all state and federal drinking water standards, as detailed in their annual reports. Chief Operator Andrew Armstrong can be reached at 386-248-9463 for further information.

Holly Hill's water originates from the Floridan aquifer, a vast underground system prevalent in Florida. The geology here is characterized by porous limestone formations dating back to the Eocene epoch, notably the Ocala Limestone. As groundwater flows through these formations, it dissolves significant amounts of carbonate minerals, leading to a high concentration of dissolved calcium and magnesium. This extensive interaction with mineral-rich bedrock is the primary reason the water supply is classified as hard, a common trait for groundwater sources in this region of Florida.

Homeowners in Holly Hill may notice the effects of this hard water, such as scale buildup in plumbing, water heaters, dishwashers, and washing machines, which can decrease their efficiency and shorten their lifespan. Appliances might need more frequent descaling, and simple remedies like flushing showerheads with vinegar can help. Many residents find installing a water softener beneficial to reduce issues like spotting on dishes, soap scum residue, and dry skin or hair after showering. While the water meets all health standards, the utility performs standard treatments like disinfection to remove potential contaminants such as bromide and tert-butyl alcohol, ensuring a safe and clean supply for all its customers can supply.

Frequently Asked Questions

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