Water Quality in Miami-Dade's Aquifer 112BSCNN: What Government Data Shows
Residents of Miami-Dade County drawing from the aquifer 112BSCNN rely on groundwater whose characteristics have been studied by the U.S. Geological Survey. Between 2010 and 2023, 190 water samples from 84 wells located 14 to 325 feet deep were analyzed to measure pH, a key indicator of water acidity or alkalinity.
The median pH value of these samples was 7.1, and the results ranged from 6.6 to 7.8 standard units. This range stays well within the Environmental Protection Agency’s secondary standard for pH, set between 6.5 and 8.5. It is important to note that this secondary standard focuses on aesthetics and corrosion potential rather than health impacts. None of the sampled wells showed pH values below 6.5, meaning the groundwater generally does not exhibit excessive acidity that could lead to increased corrosivity.
What Does pH Mean for Household Water?
Water with a lower pH is considered acidic and can be more corrosive to household plumbing and fixtures, potentially leading to metal leaching and damage over time. Conversely, harder water typically contains higher levels of dissolved minerals such as calcium and magnesium, which can cause scaling, reduce soap efficiency, and affect water taste.
While the USGS data informs about the typical pH range in the aquifer's vicinity, it does not reveal the hardness level directly, nor does it represent the specific condition of any particular household’s water. Therefore, if you are evaluating treatment options to address water acidity or hardness, testing your own water is essential to determine the precise levels of these factors.
Why Testing Your Household Water Matters
Given that pH and hardness can vary from well to well even within the same aquifer area, relying solely on regional data cannot provide a full picture of your home's water condition. Specific water tests will measure pH alongside hardness levels and other minerals to identify the exact treatment needs.
Understanding this information enables you to choose the right class of water treatment tailored to your household’s water quality challenges. For example, acidic water treatment focuses on neutralizing corrosivity, while hard water treatment aims to reduce mineral buildup and improve water usability.
How Chemical Feed Technology Addresses Acid and Hardness Problems
A documented solution designed for comprehensive water quality management is the WSP Whole House Chlorination System - Complete, Well Water. This equipment utilizes chemical feed technology, which is effective in treating well water that may have acidity and hardness issues by adjusting water chemistry and controlling contaminants.
This system ships ready to configure and can be adapted to the specific conditions identified through water testing. By integrating chemical feed treatment, it helps mitigate the effects of low pH and hardness, improving water quality for household use.
Next Steps for Your Household Water Quality Decision
- Test your household water to measure pH and hardness levels accurately.
- Compare your test results with the regional data from Miami-Dade’s aquifer 112BSCNN as a reference point.
- Consider water treatment solutions like the chemical feed-based system that can handle acid and hardness in well water.
- Consult available product information to ensure the technology matches your water chemistry needs.
Taking these steps will inform a treatment choice that best fits your household water profile, ensuring better water quality and protecting your plumbing and appliances over time.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2023-03-23. 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 112BSCNN aquifer (Miami-Dade County): 190 results from 84 wells, median 7.1 standard units, range 6.6-7.8 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 0 of 190 sampled results fell below 6.5
