Seasonal and Multi-Year Variation in Clark County Water pH
Sampling Dates Span a Decade
U.S. Geological Survey sampling in Clark County's aquifer 112OTSH ranges from 2010 to 2020, reflecting a broad timeline for water quality trends rather than short-term fluctuations.
pH Range Indicates No Seasonal Acidic Spikes Below EPA Secondary Standard
Sampled wells (21 to 65 feet deep) recorded pH between 6.8 and 8.1, with none below the EPA secondary standard lower limit of 6.5, suggesting stable conditions over seasons and years in the area sampled.

Simple Maintenance Rhythm
The Pentair system ships ready to configure and requires periodic attention to maintain peak effectiveness. Its components should be checked and serviced according to the product guidelines to ensure reliable performance against corrosivity.
What the pH Range Means Compared to Federal Standards
EPA Secondary Standard is Aesthetic, Not Health-Based
The standard pH range of 6.5 to 8.5 addresses taste, corrosion, and staining concerns, not safety. Clark County samples stayed within this range, indicating no federally defined corrosivity violation in the area.
pH Below 6.5 Would Signal Potential Corrosivity Concerns
Since none of the 46 results fell below 6.5, measured water in this area is unlikely to be strongly acidic or aggressively corrosive under typical conditions.
Order of Steps to Identify Corrosivity Issues
Begin with Visual and Taste Checks at the Tap
Look for obvious corrosion signs such as pipe discoloration or metallic taste, which might hint at corrosive water presence.
Conduct Basic pH Testing at Home
Home water test kits can establish if your water’s pH is within a non-corrosive range, providing a starting point before professional lab tests.
Consider a Laboratory Water Analysis
For precise assessment, comprehensive testing on your well water is essential to confirm corrosivity levels tailored to your household.
Clarifying Sampling Terms in Clark County’s Water Record
'Detected' Means Measured, Not Unsafe
All 46 results showed detected pH levels; detection confirms presence but is not an indicator of health risk or violation.
'Median' Reflects the Middle Value of the Data Set
The median pH of 7.1 represents the midpoint of the 46 samples, showing typical water conditions found in the area.
'Range' Captures Lowest to Highest Measurements
Range from 6.8 to 8.1 shows the variability found across wells and sampling times, useful for understanding water condition fluctuations.
Information to Record Before Seeking Treatment Advice
- Dates and results of any home or lab pH tests you have conducted
- Any observed signs of corrosion or water quality changes at your taps
- Details about your water source depth and type (well, municipal, etc.)
- Previous water treatment or filtration measures used
Equipped with local data and personal water test results, you can make informed decisions about addressing corrosive water in your home. The Pentair Corrosive Water Damaging Pipes Filter is designed to protect household plumbing by addressing corrosive conditions based on your measured needs.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2020-10-27. 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 112OTSH aquifer (Clark County): 46 results from 11 wells, median 7.1 standard units, range 6.8-8.1 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 0 of 46 sampled results fell below 6.5
