Understanding Acidic Water in Collier County from Regional Aquifer Data
Water acidity in residential wells is determined by measuring pH, a scale that shows how acidic or basic the water is. The U.S. Geological Survey collected data on pH levels from 14 wells in Collier County tapping into aquifer 112NRSD. This data, based on 30 samples from 2011 to 2019, shows a pH range from 5.7 to 8.2 standard units with a median of 6.95.
The Environmental Protection Agency recommends a secondary standard for pH between 6.5 and 8.5 to address aesthetic factors like water taste, staining, and pipe corrosion potential, not health risks. In this data, 5 of the 30 samples had pH values below 6.5, indicating occasional acidity levels that can be corrosive. However, these are regional sampling results and do not establish the pH of any individual household well or municipal water supply.
What pH Variations Mean for Residential Water Use
Lower pH water can affect plumbing and fixtures by accelerating corrosion, leading to discoloration of water and metallic taste. It may also cause etching of bathroom fixtures or increased leaching of metals from pipes. The data indicates that acidic water occurs at times in this aquifer, so households in Collier County may face these issues and benefit from treatment options that manage acidic conditions.
Because regional aquifer sampling cannot pinpoint the exact pH of your household water, testing your own well or tap water is vital. Testing provides the precise pH level and other constituents needed to determine the best water treatment approach.
Deciding on the Appropriate Treatment for Acidic Water
For households experiencing acidic water, treatment systems designed to neutralize water pH and control corrosivity are commonly sought. Among these, chemical feed systems can introduce agents that adjust the water's acidity effectively. One documented option is the Total Well — Complete Chlorination Whole-Home System, which features chemical feed technology that can help manage pH and related water quality concerns.
This system is capable of treating up to 17 gallons per day at a flow rate of 9 gallons per minute and includes a 10x54 tank with a grain capacity of 48,000. It is designed to ship ready to configure for home settings. Considering the specific characteristics of your water, such as pH and other measures, will guide whether this or another treatment class is suitable.
Next Steps for Homeowners in Collier County
- Obtain a comprehensive water test focused on pH and corrosivity indicators.
- Review test results against EPA secondary standards to understand aesthetic impacts.
- Explore treatment systems with chemical feed technology that neutralize acidic water.
- Consider total household water use and flow rates when evaluating system specifications.
By focusing on your home's unique water profile and the documented data from aquifer 112NRSD, you can make an informed choice about addressing acidic water. The Total Well system provides a well-documented technology option capable of managing water acidity effectively when testing shows it is needed.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2019-06-04. 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 (Collier County): 30 results from 14 wells, median 6.95 standard units, range 5.7-8.2 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 5 of 30 sampled results fell below 6.5
