What to Note From Your Lab pH Report Before Seeking Treatment Advice

Record the exact pH value found in your specific water test

Water test reports list pH as a measure of acidity or alkalinity on a scale typically from 0 to 14. Values below 7 indicate acidity, while those above 7 indicate alkalinity. Knowing the exact number from your own well or tap water test is essential to determine if acidic water treatment is needed.

Note the date, depth, and source of the sample in your report

Information about the sample’s collection date, depth, and whether it is from a well or surface source helps understand if conditions might fluctuate or vary by source.

Sample Size and Scope Behind Regional pH Data

167 pH results from 26 wells across Union County’s aquifer 124SPRT

The U.S. Geological Survey’s sampling from 2010 through mid-2026 covers a relatively large set of measurements that represent regional groundwater pH conditions but cannot specify any individual household’s water.

A median pH of 8.6 with a range from 7.5 to 9.1 standard units

These values are all above the EPA secondary standard lower threshold of 6.5, signaling no acidic water detections in the sampled wells for this aquifer, but individual wells may differ.

Effects of Sample and Well Depth on pH Expectations

Wells sampled were between 260 and 783 feet deep

Greater depth typically may reduce surface contamination effects and influence pH, but specific well conditions can vary widely. Shallow wells can sometimes show different pH values than deep wells.

Groundwater in Union County’s aquifer is generally not acidic by regional survey

Though the range shows alkaline water, actual pH at household taps may differ, emphasizing the need for local testing.

Household Fixtures and Processes Most Sensitive to Low pH Water

Metal plumbing and fixtures can corrode faster with acidic water

Water with low pH levels can speed corrosion in pipes and appliances, which can lead to metallic taste and staining. Identifying acidic water early helps protect plumbing infrastructure.

Water-using appliances may be affected by water corrosivity

Appliances like water heaters and dishwashers can experience damage if water is consistently acidic, potentially shortening appliance life.

Comparing Union County’s pH Data With Neighboring Counties

Use similar government sampling data for context, not to determine your own water’s pH

Neighboring counties might differ in groundwater chemistry. Comparing their median pH and range can help understand regional trends but does not override local test results.

Avoid assuming uniform water quality across county lines or well depths

Regional data is a guide, not a substitute for your own water analysis.

Summary and Government Data Source

The U.S. Geological Survey’s pH data for 26 wells and 167 samples from Union County’s aquifer 124SPRT show pH values from 7.5 to 9.1, with none below the EPA secondary aesthetic threshold for acidity. This represents regional groundwater conditions but does not specify your household’s water acidity. For treating acidic water, consider testing your own water's pH specifically. The Autotrol Acidic / Low-pH Water Filter is designed to address acidic water conditions by buffering and stabilizing pH, helping protect your home’s plumbing and appliances. This product ships ready to configure for your water system.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2026-07-30. 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 124SPRT aquifer (Union County): 167 results from 26 wells, median 8.6 standard units, range 7.5-9.1 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 0 of 167 sampled results fell below 6.5
