If you notice water-related issues such as scale buildup or unusual tastes in Florence County, WI, particularly when your water source taps into the local aquifer known as 100SDGV, understanding acid and hardness levels is key to proper treatment sizing.

How the Autotrol System Addresses Acid and Hardness

Neutralizing Acidic Water

The Autotrol Acidic Water + Hard Water (Well) System uses technology designed to counteract acidic water, adjusting pH towards neutral by adding minerals that raise pH levels within the acceptable aesthetic range.

Reducing Hardness Minerals

The system effectively reduces hardness—mainly calcium and magnesium—through ion exchange, helping prevent scale accumulation and improving water usability inside the home.

Sources of Acid and Hardness in Florence County Groundwater

Geologic Influence on pH

In Florence County’s 100SDGV aquifer, pH values recorded by U.S. Geological Survey wells ranged from 7.7 to 8.4 standard units, indicating water tends toward neutral or slightly alkaline rather than acidic. Hardness minerals typically originate from local rock and soil dissolution.

Water Depth and Mineral Content

Samples from 50 to 82 feet deep suggest groundwater interacts with subsurface geology that contributes to hardness and pH characteristics.

Reading the Median and Range of pH Data as a Homeowner

Interpreting the Median pH of 8.1

This median pH suggests water is generally not acidic, which influences how much acidity neutralization your treatment system will require.

Considering the pH Range 7.7 to 8.4

The range reflects natural variation within the aquifer’s groundwater; treatment sizing should accommodate this variability for consistent water quality.

Why Secondary Standards for pH Are Different from Health-Based Limits

Understanding EPA’s Secondary Standard

EPA sets a secondary pH standard of 6.5 to 8.5 as an aesthetic guideline, addressing taste, staining, and water corrosivity rather than health risk.

Implications for Treatment

Your water’s pH within this range is not a health concern but affects appliance longevity and comfort, justifying treatment focused on aesthetic and material protection.

Fixtures and Appliances Sensitive to Acid and Hardness

Commonly Affected Items

• Water heaters, which can deteriorate more quickly with improper pH
• Plumbing fixtures prone to scale buildup, reducing flow and efficiency
• Dishwashers and washing machines, which may experience deposits affecting performance

Why Early Attention Matters

Addressing acid and hardness helps prolong fixture life and maintain water quality throughout household water use.

Reading Certified Laboratory Test Results for pH and Hardness

What Lab Reports Show

Certified tests will provide exact pH measurements and quantify hardness minerals, essential data to confirm your specific water conditions.

Using Lab Data for System Sizing

Accurate lab results enable precise selection of a treatment system with adequate grain capacity—such as the Autotrol system’s 32,000-grain capacity—to match your household needs.

While Florence County’s aquifer data gives helpful regional insight into pH and hardness trends, it does not replace testing your own water to define exact treatment requirements. Do not assume your water matches the area median or range without verification by a certified laboratory analysis.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2024-09-12. 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 100SDGV aquifer (Florence County): 4 results from 2 wells, median 8.1 standard units, range 7.7-8.4 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 0 of 4 sampled results fell below 6.5
