Understanding What Area Data Reveals and Omits

The USGS groundwater sampling for Sauk County's aquifer 100SDGV provides an overview of water pH levels from four wells. This data, collected between August 2013 and May 2019, indicates that pH in these wells ranges from 7.3 to 8.4 standard units, with a median of 7.9. While this suggests the aquifer water generally falls within a neutral to slightly alkaline range, these results apply to the sampled wells only and do not specify your household well's conditions. To determine your water's acidity and hardness precisely, a dedicated water test must be conducted at your own source.

Seasonal and Multi-Year Variation in Area pH

The 59 sample results came from four wells sampled over nearly six years. This timeline shows that pH values stayed within the EPA secondary standard aesthetic range of 6.5 to 8.5, without dipping into acidic low pH at any point. While minor seasonal or yearly shifts could cause variation in your own well, the broad sampling period suggests the aquifer's water chemistry remains relatively stable over time.

Fixtures and Appliances First Affected by Acid and Hardness

In homes with acidic or hard water, the plumbing components and water-using appliances like water heaters, dishwashers, and washing machines typically show early signs of wear. Acidic water (low pH) can promote corrosion of metal pipes and fixtures, while hardness causes mineral buildup that reduces appliance efficiency. Even in the absence of acidic conditions confirmed by area data, hardness can still create these issues. Monitoring your household water's effects on these points helps identify the need for targeted treatment.

Comparing Sauk County's Record with Neighboring Areas Without Overinterpretation

Neighboring counties may have distinct groundwater properties due to differences in aquifers or geology. The pH values in Sauk County's aquifer 100SDGV are relatively stable and neutral to slightly alkaline. When comparing to other areas, it is important not to assume similar conditions in your well or to infer that differences imply safety or risk. Each aquifer's water quality is unique, and government sampling provides regional trends rather than household specifics.

Public-System Records Versus Private-Well Testing: What Each Establishes

Government groundwater data captures broad trends from selected wells over time, offering valuable insight into regional water quality characteristics like acidity and hardness potential. However, these records do not replace private well testing, which provides precise, current measurements of your specific water supply. For treatment decisions, private test results are essential, especially to quantify hardness levels and pH accurately at your household.

Key Information to Note Before Seeking Treatment Advice

Before consulting on treatment options, record the following from your private water test:

• Exact pH value to identify acidity or alkalinity
• Hardness level, usually measured in grains per gallon
• Source depth and water source type
• Any observed effects on appliances or plumbing

This information will clarify whether acidic conditions or hardness predominate and guide suitable technology choices.

Sample Size and Representation in the Area Data

The 59 samples across four wells in the Sauk County aquifer 100SDGV provide a moderate dataset representative of that aquifer section. While sufficient to establish general pH stability over time, these figures cannot predict localized variations in your well. Small sample numbers in an area could miss rare conditions, so personal testing remains the definitive source.

Recommended Treatment Approach for Sauk County Acid and Hardness Challenges

For households facing acid and hardness concerns in this region, the Fleck Acidic Water + Hard Water (Well) System offers a documented solution designed to handle combined acid and hard water conditions. Rated for up to 32,000 grains of hardness capacity, it ships ready to configure and addresses both factors comprehensively. Consulting your private test data helps confirm its suitability based on hardness demand and pH measurements specific to your supply.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2019-05-15. 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 (Sauk County): 59 results from 4 wells, median 7.9 standard units, range 7.3-8.4 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 0 of 59 sampled results fell below 6.5
