Scope and Sample Size Behind Bannock County pH Figures
Number of Wells Sampled
The US Geological Survey measured pH in 14 separate wells across the Bannock County aquifer, providing a regional snapshot rather than information about any specific household water source.
Number of Sample Results
A total of 29 sample measurements were taken from these wells between July 2010 and September 2011, offering repeated observations to characterize water conditions over time.
Depths of Sampled Wells
The sampled wells ranged from 75 to 280 feet deep, reflecting typical aquifer depths in the region but again not indicating the depth of a particular home’s water supply.
Limitations of the Data Set
While this data set offers valuable averages and ranges for pH, the relatively small number of wells means individual household water can still vary and should be tested directly.
Seasonal and Multi-Year Variation in Bannock County Groundwater pH
Sampling Dates Covered
Samples span from mid-2010 to late 2011, capturing more than a year to account for some seasonal changes that can affect groundwater chemistry.
Reported pH Range
The measured pH values ranged from 6.5 to 7.9 standard units, with a median of 7.4, all within the EPA secondary standard range of 6.5 to 8.5.
Consistency Across Sampling Period
None of the samples fell below the lower aesthetic limit of 6.5, suggesting that naturally strongly acidic water was not detected in this regional survey during that period.
Implications for Homeowners
Seasonal or year-to-year shifts in pH may occur but are not evident as extreme or problematic in this limited sample. Home testing remains important for confirmation.
Recognizing Household Symptoms Related to Acidic Water
Signs That May Suggest Acidic Water
- Corrosion marks or etching on plumbing fixtures
- Metallic taste in water
- Premature wear on metal appliances that use water
Signs That Do Not Confirm Acidic Water
- Cloudiness or sediment spots unrelated to pH
- Odors or colors caused by other contaminants
- Water pressure issues
Why Symptoms Alone Are Insufficient
Because many symptoms can arise from causes other than acidity, an accurate laboratory test of the home’s specific water source is essential before choosing treatment.
Ruling Out Causes: Household Checks and Testing Steps
Start with Simple Checks
Review plumbing materials for susceptibility to acidic water effects and check for visible fixture damage.
Obtain Laboratory pH Testing
Submit a water sample from the home well or tap to a certified laboratory to determine actual pH rather than relying on regional data alone.
Consider Testing for Related Parameters
Because pH shifts can link to other water chemistry issues, testing for total dissolved solids or corrosion indicators can refine understanding.
When to Consider Treatment Capacity
For larger households or properties with fluctuating occupancy, testing frequency and treatment sizing should reflect increased water use and storage needs.
Adjustments for Different Household Situations
Large or Multi-Occupant Homes
Water demand and treatment flow rates increase, so treatment solutions should be capable of handling higher volumes without performance loss.
Seasonal or Second Homes
Water chemistry may shift after periods of inactivity, making pre-occupancy testing advisable to ensure water quality before use.
Properties Using Private Wells
Private wells can diverge from regional averages; direct testing is critical to identify acidic water and plan treatment accordingly.
Summary
The Bannock County aquifer sampling records show pH values consistently within the EPA’s secondary aesthetic range, indicating no widespread acidic water problem in the regional groundwater. Individual household water characteristics may differ, so confirming pH through local testing is vital before deciding on treatment.
For households that identify acidic water after testing, the C-Series Acidic / Low-pH Water Filter ships ready to configure and offers a documented method to address low-pH water efficiently.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2011-09-21. 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 aquifer (Bannock County): 29 results from 14 wells, median 7.4 standard units, range 6.5-7.9 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 0 of 29 sampled results fell below 6.5
