What Water Sampling Reveals About Orange County Aquifer Water
The U.S. Geological Survey has collected water samples from wells in Orange County, Florida, specifically the 122HTRNN aquifer. Data from 34 samples taken between 2010 and 2026 provide insight into the typical water chemistry of this regional source. The measured pH values ranged from 7.2 to 8.2 standard units, with a median of 7.5. This range is entirely within the EPA secondary standard for pH, which spans 6.5 to 8.5. The secondary standard addresses aesthetic and corrosivity concerns rather than health safety, reflecting factors such as taste, staining, and pipe corrosion potential.
In this area, water is not acidic according to these background measurements; acidic water has a pH below 7.0 and often below the lower secondary standard limit of 6.5. The sampled wells were about 75 feet deep, representing groundwater rather than surface water sources. While presence of hardness minerals like calcium and magnesium was not reported in these samples, groundwater in Florida commonly exhibits hardness that can cause scaling and reduce soap effectiveness.
Why Testing Your Own Well Water is Important
Since these data represent regional averages and not your household water, you should conduct your own water testing to understand your specific hardness and pH levels. Hardness affects scale buildup and appliance efficiency, while pH influences corrosion and metal leaching risks. Testing identifies whether your water tends toward acidic conditions (low pH) or alkalinity (high pH) and establishes the degree of hardness. This knowledge guides selection among treatment options tailored to your home’s water profile.
Treatment Options for Managing Acid and Hardness
Treatment selection depends on the combined challenges of acidity and hardness. Some water softeners primarily address hardness by ion exchange but do not correct low pH or disinfect water. Chemical feed systems that add controlled amounts of chlorine provide disinfection and can adjust corrosivity by altering pH and reducing organic contaminants.
For residences in Orange County facing both acid and hardness issues, a documented solution is the Total Well — Complete Chlorination Whole-Home System. This system uses chemical feed technology to treat entire home water supply, targeting disinfection and improving water chemistry. Technical specifications include a grain capacity of 48,000, daily flow rate capability of 17 gallons per day, and peak flow of 9 gallons per minute through a 10x54 inch tank. These parameters suit households needing comprehensive treatment addressing multiple water quality aspects.
How This System Addresses Combined Problems
- Adjusts Corrosivity: By chemical feed, the system stabilizes pH and reduces water aggressiveness toward pipes and fixtures.
- Controls Hardness: While primarily focused on chlorination, integration with pre-softening units is possible to manage scale buildup.
- Provides Whole-Home Protection: Treats all water entering the residence ensuring consistent water quality at every tap.
Next Steps for Homeowners
Before selecting a treatment system, confirm your household’s specific water profile through certified laboratory testing for pH, hardness, and other relevant parameters. Understanding the exact conditions helps determine if a chemical feed system like the Total Well fits your needs, or if a dedicated softener or pH adjustment solution is more appropriate. Combining testing with informed product choice ensures effective treatment and protects plumbing and appliances long term.

Source: USGS groundwater sampling. Sampled 2026-05-27. These figures describe groundwater sampled in this area. They are not a test of any individual private well - only a test of that well can establish its own water.
On record: U.S. Geological Survey sampling of pH in the 122HTRNN aquifer (Orange County): 34 results from 1 wells, median 7.5 standard units, range 7.2-8.2 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 0 of 34 sampled results fell below 6.5
