What Government Sampling Reveals About Water Acidity in Orange County
The U.S. Geological Survey has collected water quality data from wells tapping the 112NRSD aquifer in Orange County, FL. Their data, gathered from a 15-foot deep well sampled 33 times over 2010–2026, shows that pH values ranged between 6.0 and 8.2, with a median of 7.3 standard units. The pH scale measures acidity or alkalinity, with lower numbers indicating acid conditions and higher numbers indicating alkaline.
According to the Environmental Protection Agency (EPA), the secondary standard for pH—which relates to water’s aesthetic qualities and corrosiveness—suggests an acceptable range from 6.5 to 8.5. It is important to understand that this is not a safety or health guideline but relates to potential taste, staining, and pipe corrosion issues.
In the sampled data, 6 out of the 33 results fell below 6.5, indicating that low pH (acidic water) can sometimes occur in this region. Acidic water can cause metal pipe corrosion and unpleasant taste, and it may also complicate the management of water hardness.
Water Hardness Considerations in Orange County
Although hardness is not directly measured by pH, hardness in water typically consists of dissolved minerals like calcium and magnesium. Hard water can cause scale buildup on fixtures and inside pipes, which affects household appliances and water flow.
Managing both acidity and hardness simultaneously requires careful selection of treatment methods, as these water characteristics influence each other and how treatment chemicals behave.
What Testing Your Own Water Means
Government sampling provides area-wide averages and ranges but does not specify conditions for any individual well. To accurately know the acidity and hardness levels of your household water source, specialized water testing is necessary. A comprehensive test will include pH, hardness, and other relevant parameters to guide effective treatment choices tailored to your home.
Two Approaches to Address Acid and Hardness
Residential water treatment often relies on either mechanical or chemical solutions:
- Mechanical treatments such as traditional water softeners use ion exchange to reduce hardness minerals but do not address water acidity directly.
- Chemical feed systems introduce controlled amounts of chemicals to adjust pH and oxidize contaminants, effectively managing both acidity and hardness effects.
In regions like Orange County where pH values can dip below the secondary standard, chemical feed systems can help maintain water balance and protect plumbing.
The Documented Chemical Feed Solution: Total Well System
The Total Well — Complete Chlorination Whole-Home System employs a chemical feed technology designed to treat water quality issues including acidity and hardness-related concerns. It delivers up to 17 gallons per day at 9 gallons per minute through a 10x54 inch tank and offers a 48,000-grain capacity.
This system adjusts water pH and provides chlorination to reduce corrosivity and scale formation. It ships ready to configure, allowing for straightforward integration with existing household water setups.
Summary and Next Steps
The Orange County 112NRSD aquifer presents a pH range indicating occasional acidic conditions that may affect water quality and equipment longevity. Alongside hardness, these factors call for treatment approaches capable of balancing water chemistry.
Exploring chemical feed systems like Total Well can be a proactive step to maintaining water quality in homes facing combined acid and hardness challenges. Confirming your own water parameters through testing will provide the information necessary to select the best option.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2026-05-13. 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 112NRSD aquifer (Orange County): 33 results from 1 wells, median 7.3 standard units, range 6.0-8.2 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 6 of 33 sampled results fell below 6.5
