Understanding Acidic Water in Martin County Residential Wells

Water acidity, expressed as pH, influences many aspects of household water quality including taste, plumbing wear, and appliance longevity. The U.S. Geological Survey’s groundwater sampling for Martin County’s 112NRSD aquifer collected three samples from a well 125 feet deep between November 2019 and September 2020. These samples showed pH levels ranging from 6.9 to 7.8 standard units, with a median at 6.9.

According to the EPA’s secondary standard, aesthetic and corrosivity guidelines set pH between 6.5 and 8.5 standard units. None of the samples fell below this range, which suggests that acidic water conditions in this aquifer are generally moderate. However, water on the lower end of this range can still create challenges in household plumbing and with water-using appliances.

What the Data Means for Your Home

The reported pH range provides a general sense of water acidity in the local aquifer but does not substitute for testing your own water supply. Variations can occur at each well depending on depth, surrounding geology, and other factors. To understand how acidic your household water truly is—and how it may be affecting your equipment—you will need a specific pH test of your well or tap water.

Effects of Acidic Water on Residential Equipment

Acidic water, even within allowable pH ranges, can be corrosive to plumbing materials like copper and iron. This corrosion can cause metal leaching, discoloration, unpleasant tastes, and deterioration of fixtures. Existing water treatment equipment that cannot fully manage the acidity may allow these effects to persist or worsen, shortening the lifespan of household infrastructure.

Why Existing Equipment Might Not Keep Up

• Neutralizing capacity may be insufficient to maintain stable pH.
• Equipment wear and media depletion over time reduces effectiveness.
• Water quality variations increase treatment complexity.
• Inadequate system sizing or aging components limit performance.

How Neutralizer Technology Can Help

A neutralizer system is designed to raise the pH of acidic water by adding a base, such as calcite or magnesium oxide, to neutralize acidity and reduce corrosivity. This technology can improve water from mildly acidic to a more balanced state within the EPA secondary pH range, protecting plumbing and appliances from acid-related damage.

The Fleck Acidic Water + Hard Water (Well) System employs such a neutralizer approach with a grain capacity of 32,000. This capacity supports effective treatment volumes for household use, helping water treatment keep pace where prior equipment struggles.

What To Consider When Upgrading Your System

• Test your water pH and hardness to verify the specific conditions.
• Evaluate your current equipment’s neutralizing capacity against your water’s acidity.
• Choose a system with sufficient grain capacity to handle your household demand.
• Ensure the system ships ready to configure to your household needs.

Addressing acidic water effectively requires understanding both your water’s chemistry and your treatment equipment’s capabilities. With accurate testing and appropriate neutralizer technology, you can protect your home’s water quality and infrastructure from the impacts of acid-corrosive conditions prevalent in Martin County’s aquifer.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2020-09-17. 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 (Martin County): 3 results from 1 wells, median 6.9 standard units, range 6.9-7.8 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 0 of 3 sampled results fell below 6.5
