Understanding Groundwater Acidity in Miami-Dade County
The Miami-Dade County aquifer is a key source of groundwater for many households. Government sampling from the U.S. Geological Survey provides insight into the natural pH range of water in this aquifer. Between 2010 and 2016, 22 samples from 10 wells 61 to 100 feet deep showed pH values ranging from 6.9 to 7.9 standard units, with a median of 7.2.
This pH range is within the EPA secondary standard of 6.5 to 8.5, which is a guideline focused on aesthetics and corrosion potential rather than health safety. Water with lower pH levels tends to be acidic and can cause corrosion in household plumbing and fixtures.
What the Data Does and Does Not Tell You
These measurements represent the aquifer area broadly, not any specific well or household supply. Because pH can vary by depth, location, and time, a private well's water could differ from the reported range. To determine your home's specific water acidity, testing of your actual water supply is essential.
Why Acidic Water Matters to Your Household
Acidic water can react with metals in plumbing systems, accelerating corrosion and causing staining or metallic tastes. Even if existing treatment equipment is present, escalating effects can indicate that your system is no longer adequately controlling acidity or its consequences.
Since the pH in this aquifer rarely falls below 6.5 according to sampling, issues may be intermittent or influenced by other factors such as water chemistry changes or system wear. This suggests that enhanced treatment capacity or an updated approach might be required to keep up with your household's demand or evolving water conditions.
Choosing a Chemical Feed System for Whole-Home Acid Control
A chemical feed system designed for well water can adjust water chemistry to minimize acidity and its corrosive effects. One such system known for reliability is the Total Well — Complete Chlorination Whole-Home System, which ships ready to configure and handles flow rates up to 9 gallons per minute with a daily capacity of 17,000 gallons.
This system uses a chemical feed method to treat the entire home's water supply, offering both chlorination and acid control in a single unit. With a tank size of 10x54 inches and a grain capacity of 48,000, it is intended to meet substantial household water treatment needs and maintain performance even when previous equipment is outpaced.
What to Test and Consider Next
- Test your household's water pH to confirm if acidity is a current concern.
- Assess your flow and volume needs to ensure that a chemical feed system with the specified capacity is appropriate.
- Evaluate existing equipment performance to determine if capacity or technology enhancements are necessary.
Addressing acidic water with a well-matched chemical feed system like Total Well can help maintain plumbing integrity and water quality, especially when prior treatment no longer meets household demand.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2016-08-31. 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 aquifer (Miami-Dade County): 22 results from 10 wells, median 7.2 standard units, range 6.9-7.9 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 0 of 22 sampled results fell below 6.5
