Sample Size and Well Depth Considerations in Livingston County

Samples and Wells Behind Local pH Data

The U.S. Geological Survey collected 20 pH samples from 8 wells within Livingston County's aquifer 112SDGV between August 2016 and July 2024. These wells ranged from 49 to 116 feet in depth. This limited data set provides a median pH of 7.55 standard units across the area, representing typical groundwater pH in this part of the county. While useful for understanding regional water quality trends, the small number of wells means the data may not fully represent all local variations.

Range and Stability of pH Values

Measured pH values for the sampled wells ranged from 7.0 to 7.9 standard units, all falling within the EPA secondary standard for pH (6.5 to 8.5). None of the samples exhibited pH levels below 6.5, which would indicate acidic or low-pH water. This suggests that, generally, groundwater in this aquifer does not display acidic conditions at levels typically associated with aesthetic or corrosiveness concerns.

Comparing Livingston County pH Data with Neighboring Areas

Regional Variation Without Overinterpretation

When comparing Livingston County’s aquifer pH record with nearby counties, it is important to recognize that aquifer geochemistry varies naturally. Differences in sampling periods or well depths can influence observed pH. The pH range found locally falls within typical groundwater pH values seen in adjoining areas, so minor variations should not be overread as unique water quality problems. Local well testing is needed to confirm an individual water source’s pH status.

Additional Questions for Commercial or Industrial Water Users

Household vs. Commercial Concerns

While household water users generally focus on aesthetic issues related to pH, commercial or industrial users may ask about corrosion rates, equipment compatibility, or process impacts related to pH fluctuations. Such users often require more detailed monitoring and may consider different treatment approaches tailored to their scale and water demands.

Adjusting Considerations for Large or Seasonal Households

Household Size and Water Usage Patterns

Larger households or seasonal residences should consider how water pH may interact with their specific plumbing materials and usage patterns. Although regional sampling indicates typical pH levels, individual water may differ due to local well conditions or seasonal groundwater changes. This can influence the choice and sizing of water treatment options.

Why EPA Secondary Standards Differ from Health-Based Limits

Aesthetic and Corrosivity Guidelines Versus Safety Thresholds

The EPA secondary standard for pH (6.5 to 8.5) addresses aesthetic factors such as taste, staining, and corrosivity potential. It is not a health-based limit and does not indicate safety concerns when pH values fall outside this range. The Livingston County aquifer samples all remain within this range, meaning pH-related health risks are not indicated by this data.

Next Steps: Testing Your Household Water

The Definitive pH Determination

Because government data represent area-wide sampling and not your specific well or tap, the only way to know your household water’s pH is through an individual laboratory test. This test will provide an accurate pH measurement for your water source. Should acidic (low-pH) water be confirmed, solutions like the Autotrol Acidic / Low-pH Water Filter system ship ready to configure and can address aesthetic and corrosivity concerns associated with your water quality.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2024-07-31. 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 112SDGV aquifer (Livingston County): 20 results from 8 wells, median 7.55 standard units, range 7.0-7.9 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 0 of 20 sampled results fell below 6.5
