The U.S. Geological Survey has documented pH levels in Franklin County's aquifer 000OVBD, based on 45 groundwater samples from 9 wells collected between 2010 and 2025. These results present a median pH of 7.6 standard units, with values ranging from 7.0 to 8.2 standard units. All recorded pH values fall within the U.S. Environmental Protection Agency's secondary standard range of 6.5 to 8.5, which relates to water aesthetics and corrosion potential but does not indicate a health risk.

Interpreting 'Detected', 'Median', and 'Range' in the Sampling Record

In the context of these measurements, 'detected' means that all 45 samples recorded pH values measurable by the instruments, with none below the thresholds of detection. The 'median' value of 7.6 is the midpoint of all recorded pH values, signifying that half of the samples were higher and half were lower than this figure. The 'range' from 7.0 to 8.2 shows the spread of pH values observed across all sampled wells, indicating natural variability within the aquifer. These figures describe the aquifer's characteristics and should not be assumed to represent any specific household's water without personal testing.

Household Symptoms Associated with Acidic Water and What They Do Not Indicate

Typical signs that may suggest acidic water include diminished lifespan of plumbing fixtures, small amounts of staining or etching on pipes, and a metallic taste. However, these symptoms can arise for various reasons unrelated to water pH, such as pipe material or other water chemistry factors. Conversely, the absence of such symptoms does not guarantee neutral pH but suggests a lower likelihood of acidic water. Identifying acidic water specifically requires proper testing rather than relying solely on household signs.

Using Median and Range Data: A Practical Interpretation for Homeowners

The median pH of 7.6 indicates that most sampled wells in Franklin County's aquifer deliver neutral to slightly basic water, which is typical for many groundwater sources. The lowest measured pH of 7.0 is still above the EPA's lower aesthetic limit, meaning strongly acidic conditions were not observed in these samples. For homeowners, this suggests acidic water is uncommon in this area according to government records, but individual well conditions can vary.

Steps to Confirm and Address Acidic Water

• Initial Check: Examine plumbing and fixtures for signs of corrosion or wear that could relate to pH issues.
• Home Water Test: Conductor acquire a certified laboratory pH test of your household water to establish the actual pH level at your point of use.
• Water Quality Analysis: Consider testing other water chemistry parameters that influence corrosion and taste.
• Treatment Consideration: If acidic water is confirmed, equipment like the Pentair Acidic / Low-pH Water Filter ships ready to configure as a targeted solution to help neutralize low pH levels.

Maintenance Rhythm for the Pentair Acidic / Low-pH Water Filter

This product is designed for straightforward upkeep without the need for professional service. Regular replacement of filter media or components, as recommended by the manufacturer, ensures continued performance. Homeowners should monitor water quality periodically to evaluate ongoing effectiveness.

In summary, the pH data from 45 samples across nine wells in Franklin County's aquifer 000OVBD reveals a consistent median pH of 7.6 and a range from 7.0 to 8.2, all within EPA secondary aesthetic and corrosion guidelines. To understand your household water conditions, laboratory testing offers the definitive measure. The government source for these data is accessible at the U.S. Geological Survey monitoring location page.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2025-09-29. 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 000OVBD aquifer (Franklin County): 45 results from 9 wells, median 7.6 standard units, range 7.0-8.2 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 0 of 45 sampled results fell below 6.5
