If you observe multi-year pH variation in groundwater sampling
Data collected by the U.S. Geological Survey from 2011 to 2022 for wells in Gibson County's aquifer 111ALVM shows pH values ranging from 5.0 to 6.7 standard units, with a median of 5.75. This record reveals that over about a decade, water in this aquifer often falls below the EPA’s secondary standard pH range of 6.5 to 8.5, indicating the water tends toward acidity in this area. However, these figures represent regional sampling, not your specific well, and reflect natural seasonal and hydrologic variation over time.
If you are comparing household water treatment needs to commercial or industrial questions
Unlike commercial or industrial water users who must consider processes with precise pH requirements or regulatory constraints, most household decisions focus on aesthetic, plumbing, and corrosion factors. Industrial operators might need detailed analyses of how water chemistry interacts with equipment, while residential users can prioritize minimizing acidic water’s effects on pipes and taste. This difference means household water treatment selection centers on addressing corrosivity and related issues rather than strict regulatory compliance.
If you want to understand the meaning of detected, median, and range in this pH record
The reported pH values come from four samples from a single well sampled between 21 and 21 feet deep. 'Detected' means pH was measured in all samples; there were no non-detects. 'Median' shows the middle value (5.75), reflecting typical conditions. The 'range' (5.0 to 6.7) indicates observed variation over time, not extremes outside normal conditions. Note the EPA secondary standard for pH addresses water taste and plumbing effects, not safety.
If you want to understand how pH becomes low in Gibson County groundwater
Low pH in this region’s groundwater can result from natural geochemical interactions within the aquifer, including carbon dioxide dissolution and mineral reactions that acidify water. Agricultural practices and soil composition also influence pH but are accounted for in the regional sampling data. This insight helps explain why acidic water is common in this aquifer and why testing your well's water is essential for specific conditions.
If you interpret the regional pH median and range for your household water
As a homeowner, observing a median pH near 5.75 and a range that dips below the secondary standard’s lower limit suggests your water may be acidic enough to cause taste concerns or minor pipe corrosion. Confirming your own water's pH through testing is advisable before choosing treatment. For acidic water in this range, a treatment filter designed to raise pH or buffer the water’s acidity, such as the C-Series Acidic / Low-pH Water Filter, ships ready to configure and can address these conditions effectively.
If you manage water use in a large household, second home, or seasonal property
Water consumption and usage patterns influence how treatment systems perform. Larger households or residences used seasonally might require filters sized and configured differently to handle varied flow demands and stagnation risks that could affect water chemistry. While the underlying acidic condition remains consistent with area data, these use factors inform treatment capacity and maintenance intervals.
Summary: Government sampling shows that aquifer 111ALVM in Gibson County often contains acidic groundwater with pH values commonly below the EPA secondary range. While this data informs what a homeowner might expect, specific testing of household water is essential before selecting treatment. For acidic water near these levels, the C-Series Acidic / Low-pH Water Filter offers a practical solution tailored to manage low-pH conditions and protect plumbing and water quality.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2022-04-21. 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 111ALVM aquifer (Gibson County): 4 results from 1 wells, median 5.75 standard units, range 5.0-6.7 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 3 of 4 sampled results fell below 6.5
