Water pH Variability in Hillsborough County's Aquifer 120FLRD
The U.S. Geological Survey collected groundwater samples from 20 wells in Hillsborough County's aquifer system (designated 120FLRD) between 2010 and 2012. These wells, ranging from 29 to 299 feet deep, were tested for pH, a measure indicating the water's acidity or alkalinity. Results show a median pH of 7.2 standard units within a range from 5.5 to 8.0. Notably, 5 out of 61 samples fell below the EPA secondary standard lower bound of 6.5, which relates to aesthetic concerns such as corrosivity and taste, not health risks.
What This Means for Your Household Water
This range in pH illustrates that acid conditions can occur in groundwater across this region, although many samples fall within neutral or slightly alkaline levels. Acidic water (pH below 6.5) can lead to corrosion of pipes and fixtures, causing metallic tastes, staining, and potential damage to plumbing components. Combined with water hardness—which involves minerals like calcium and magnesium—acidic water may exacerbate scale buildup and reduce appliance lifespan.
Understanding Your Own Water Conditions
Because the USGS data reflect area-wide sampling, they do not specify the pH or hardness of your household water supply. To assess your home's water condition accurately, specific testing for pH and hardness is necessary. This testing will determine the exact acidity and mineral content that might be present, guiding decisions on treatment options.
Testing providers can analyze your water for pH and total hardness levels. This helps to identify if your water is acidic, hard, or both, which is crucial since each condition impacts plumbing and water quality differently.
How Chemical Feed Technology Addresses Acid and Hard Water
When acid and hardness issues are confirmed, specialized water treatment solutions can mitigate these effects. One proven approach is a chemical feed system, designed to introduce precise amounts of chemicals that neutralize acidity and reduce hardness-related problems. Such a system is capable of handling water flow rates up to 9 gallons per minute and daily volumes up to 17 gallons per day, with a capacity to treat up to 48,000 grains of hardness.
This solution ships ready to configure and integrates into your household water system to protect plumbing and improve water quality by balancing pH and managing mineral content. It operates with a 10x54 inch tank size, offering robust capacity for residential water demands.
Next Steps for Homeowners
- Obtain precise testing of your home's water supply for pH and hardness.
- Review the results to determine if acidity or hardness exceeds levels that could affect plumbing or water taste.
- Consider deploying a chemical feed system that neutralizes acid and addresses hardness effectively.
By understanding area-wide water chemistry data and correlating it with your specific household test results, you can make informed decisions for managing acid and hardness concerns. This approach helps preserve your plumbing system and maintain better water quality for everyday use.

On record: U.S. Geological Survey sampling of pH in the 120FLRD aquifer (Hillsborough County): 61 results from 20 wells, median 7.2 standard units, range 5.5-8.0 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 5 of 61 sampled results fell below 6.5
