Government sampling from Clermont County’s aquifer 112OTSH shows groundwater pH values ranging from 7.3 to 8.0 standard units with a median of 7.3 based on four samples taken in 2019. This pH range falls comfortably within the U.S. Environmental Protection Agency’s secondary standard of 6.5 to 8.5, which addresses water aesthetics and potential corrosivity rather than health risks. None of the sampled results indicated acidic water below 6.5, which is generally where water begins to exhibit corrosive characteristics.
1. How Treated Tap Water Differs with an Autotrol Acidic / Low-pH Water Filter
When water from a source with lower pH is treated through the Autotrol Acidic / Low-pH Water Filter, it undergoes adjustment to reduce acidity, helping protect household plumbing and fixtures. This technology conditions water to raise pH levels within recommended aesthetic and corrosivity guidelines without affecting safety parameters. Water treated this way typically feels less harsh and minimizes potential metal leaching or pipe degradation associated with acidic water. This effect is noticeable as water comes from the tap, providing a more balanced pH that aligns with the region’s typical groundwater profile.
2. Comparing Clermont County pH Records with Neighboring Counties
Evaluating pH data from Clermont County in relation to surrounding counties demands caution. While local geology affects groundwater chemistry, nearby aquifers may show naturally different pH ranges due to varying mineral content or recharge sources. Comparing median and range values side-by-side helps establish whether your area has typical groundwater pH or possibly lower acidity concerns. However, differences in sampling frequency, depth, and well location also influence recorded values. Thus, broad comparisons can identify regional trends but do not substitute for specific local water testing.
3. Interpreting the pH Range Against EPA Secondary Standards
The EPA secondary standard for pH is 6.5 to 8.5 standard units, designed as a guideline for water aesthetics and to prevent corrosion in plumbing. The four samples from Clermont County, all between 7.3 and 8.0, are well within this range. This indicates that groundwater here is unlikely to exhibit corrosive behavior linked to acidity. However, pH is a continuous scale rather than a strict ceiling or floor; water slightly below or above the standard does not necessarily pose a health risk. It simply means there could be potential for taste or pipe-related effects, which water treatment can address.
4. Understanding Certified Laboratory pH Tests for Homewater
A certified laboratory reports pH as the concentration of hydrogen ions measured on a logarithmic scale from 0 (strongly acidic) to 14 (strongly alkaline). For household water, typical reports include the pH value along with notes referencing local guidelines or standards. Homeowners receiving a laboratory pH report should note the exact numeric value and compare it with regional ranges and EPA secondary standards but should not assume this single reading reflects a constant condition. Water pH can fluctuate over time due to source changes, seasonal effects, or well depth variability.
5. A Worked Example: Reading Clermont County’s Median and Range for Your Water Assessment
Imagine a homeowner examining the 2019 groundwater data from Clermont County’s aquifer 112OTSH. The median pH of 7.3 reflects the midpoint of sampled values, while the range from 7.3 to 8.0 signals slight natural variation among wells sampled at 80 feet depth. This median indicates that acidic conditions below pH 6.5 were not found. The homeowner can therefore consider that their well water is likely near neutral in acidity but should still conduct a direct test to confirm their specific water’s pH. This information aids in deciding which technical approach—such as selecting the Autotrol Acidic / Low-pH Water Filter—might best address potential acidity and protect their plumbing.
Despite the useful insight from area sampling, homeowners should not conclude that their own water exactly matches these values. The area data provides context but is not a substitute for a direct, certified laboratory test of the well or tap water in question. Only such a test can establish the actual pH and guide the choice of appropriate treatment technology to manage acidity effectively.

On record: U.S. Geological Survey sampling of pH in the 112OTSH aquifer (Clermont County): 4 results from 1 wells, median 7.3 standard units, range 7.3-8.0 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
