Water Quality Characteristics in Orange County's Aquifer 120UFAQ
According to groundwater sampling conducted by the U.S. Geological Survey in Orange County, Florida, specifically within the 120UFAQ aquifer, the pH levels in water from wells (sampled at 520 feet depth) consistently measured within the range of 7.5 to 8.0 standard units. The median pH across five samples taken between 2015 and 2026 was 7.8.
This pH range lies comfortably within the Environmental Protection Agency's secondary (aesthetic) standard for pH of 6.5 to 8.5. It is important to note that this secondary standard addresses water's taste, odor, appearance, and corrosivity, rather than health safety. No samples fell below the lower pH threshold of 6.5, indicating that acidic conditions typical of corrosive water are not prevalent in these tested wells.
What This Means for Your Home's Water System
Even though aquifer data suggests water is not highly acidic in this region, households regularly dealing with both acidic and hard water conditions may find their current equipment unable to maintain balanced water quality. Hardness, typically caused by minerals such as calcium and magnesium, can lead to scale buildup and inefficiency in appliances and plumbing. Meanwhile, even slight acidity may promote corrosion and damage.
Because the government data represents area-wide aquifer conditions and not your specific well, it is crucial for homeowners experiencing these issues to conduct testing of their own water supply. This will determine the exact hardness levels and pH balance present in their household water, which can vary from regional averages due to well depth, aquifer variations, and local geochemistry.
Addressing Combined Acidic and Hard Water Conditions
Treating both acidity and hardness simultaneously requires technologies capable of neutralizing pH while reducing mineral content. One documented approach features a neutralizer system designed to handle household water challenges by increasing pH to reduce corrosion potential and managing mineral hardness to prevent scale.
The Fleck Acidic Water + Hard Water (Well) System ships ready to configure and has a grain capacity rated at 32,000, providing robust mitigation for hard water minerals. By adjusting pH and softening water, this solution helps protect plumbing, improve appliance efficiency, and enhance water’s aesthetic qualities.
Considerations When Upgrading Your Water Treatment
- Testing your water for pH and hardness is the essential first step to confirm the specific conditions your system must address.
- Evaluating system capacity relative to household water usage ensures long-term performance without frequent maintenance.
- Understanding that aquifer-wide data provides a helpful but indirect guide means your water quality may have unique characteristics to monitor.
Choosing appropriate water treatment technology that targets both acidity and hardness can extend the life of your plumbing, improve water taste and appearance, and reduce maintenance needs. The Fleck neutralizer-based system offers a documented, ready-to-configure option suited to these combined challenges in Orange County's 120UFAQ aquifer area.

On record: U.S. Geological Survey sampling of pH in the 120UFAQ aquifer (Orange County): 5 results from 1 wells, median 7.8 standard units, range 7.5-8.0 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 0 of 5 sampled results fell below 6.5
