Is your home's water acidic, and if so, how serious might that be? In Overton County, Tennessee, groundwater samples show a pH range that includes mildly acidic values, meaning your water could likewise vary. Checking your own water's pH is essential to know its specific condition.

Seasonal or Multi-Year pH Variation in Overton County, Aquifer 327PSLVL

Sampling Dates and Range Recorded by USGS

• The U.S. Geological Survey collected groundwater samples between January 14 and 22, 2026.
• Samples came from one well at 228 feet depth in Overton County's aquifer 327PSLVL.
• The pH values ranged from 6.1 to 8.2 standard units, showing both acidic and neutral to slightly alkaline conditions.

Interpreting the Median and Range for a Household Water User

Understanding pH Values in Context

• The median pH was 7.8 standard units, which is near neutral and generally not acidic.
• However, one-third of the samples indicated a pH below 6.5, the lower bound of the EPA's secondary range.
• This secondary standard addresses aesthetic factors such as taste and potential corrosivity, not health risks.

Plumbing Material and Age Effects Separate from Source Water

How Your Home's Pipes Influence Water pH Impact

• Older plumbing materials or certain metals can interact with water, potentially making acidic water effects more noticeable.
• This interaction can cause staining or accelerate pipe wear independent of source water pH.
• Newer or lined pipes may be less affected even if the source water is mildly acidic.

Fixtures and Appliances Most Sensitive to Acidic Water

First Signs and Areas of Concern

• Faucets, shower heads, and water heaters often show early signs due to constant water exposure.
• Appliances using hot water, such as dishwashers, may also reflect acidic water effects sooner.
• These points are good locations to monitor for any visible changes or damage.

Evaluating Treatment Needs Based on Household Water Use

How to Match Solution Capacity to Daily Demand

• Determine your household's daily water consumption to assess treatment system requirements.
• The C-Series Acidic / Low-pH Water Filter ships ready to configure for residential water volumes.
• This system is designed to address acidic water effects documented in the area’s groundwater.

Understanding Sampling Terms: Detected, Median, and Range

Clarifying What the USGS Data Shows

• "Detected" means the instrument measured the constituent—in this case, pH values for water samples.
• The "median" is the middle value amidst the measured results, representing a typical pH level in this sampling.
• The "range" shows the span from lowest to highest pH found, reflecting natural variability in the aquifer.
• These data are for this area’s aquifer and do not specify water quality in any individual well or household.

In summary, Overton County's aquifer 327PSLVL shows pH values ranging from slightly acidic to neutral, indicating potential but not certain acidic water conditions at the tap. Homeowners should test their own water for precise pH levels and consider managing effects with appropriate treatment, such as the C-Series Acidic / Low-pH Water Filter, to suit their household usage and appliance needs.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2026-01-22. 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 327PSLVL aquifer (Overton County): 3 results from 1 wells, median 7.8 standard units, range 6.1-8.2 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 1 of 3 sampled results fell below 6.5
