How Public-System Records Differ from Private-Well Testing in What They Establish
Test results reflect samples from area wells, not individual household sources
Federal groundwater data for Washington County’s 100SDGV aquifer shows pH values measured from four samples in one well over 2013-2024. These indicate the typical pH range found regionally but do not define your home's specific water acidity.
Sampling depth affects pH readings but is not a household guarantee
The sampled well was about 94 feet deep. Water pH can vary with depth and local geology. A private well at a different depth may show different acidity levels.
Government data measures pH on a continuous scale, not pass/fail levels
Measured pH values ranged from 7.1 to 7.9 standard units with a median of 7.4. This reflects mostly neutral to slightly alkaline water by EPA secondary standards.
EPA secondary standards for pH focus on taste and corrosion aesthetics, not health
The EPA defines acceptable pH for aesthetic reasons as 6.5 to 8.5 standard units. None of the samples fell below 6.5, so the recorded water is not strongly acidic as defined by this criterion.
How the Treated Water Differs at the Tap Once the Documented Technology Is in Place
Treated water achieves a stable, neutral pH that helps protect plumbing
The C-Series Acidic / Low-pH Water Filter neutralizes low-pH water, reducing corrosivity and preserving fixtures.
The filtering process does not alter water safety or essential mineral content
This system’s treatment focuses on adjusting pH rather than removing beneficial minerals, maintaining overall water quality.
Households may notice less metal staining and reduced metallic taste
Neutralized water often results in fewer signs of corrosion such as staining on sinks or fixtures and improved taste.
What Changes for a Large Household, a Second Home, or a Seasonal Property
Larger households require treatment capacity sized for higher water use
Daily water demand increases with the number of residents, requiring consideration of filter capacity and flow rates.
Second or seasonal homes may need vacation mode or maintenance planning
Water quality impacts can vary with periods of non-use; periodic system flushing or standby settings may be advisable.
Monitoring water pH over time helps gauge seasonal or local variations
Conditions in wells or municipal sources can shift; testing before and after periods of non-use ensures stable water quality.
A Worked Example: Reading the Record's Median and Range as a Homeowner Would
Median pH of 7.4 indicates mostly neutral water typical for this aquifer
A reading near 7.4 represents water that is neither acidic nor alkaline, falling comfortably within EPA’s aesthetic guideline.
Range from 7.1 to 7.9 suggests some natural variability across measurements
This span shows that pH may fluctuate with time, depth, or location but remains close to neutral.
No samples below 6.5 means strong acid conditions were not detected in this data set
Though localized wells could differ, regional testing does not show acidic water levels that trigger aesthetic concerns.
How to Judge Treatment Capacity Against the Household's or Facility's Daily Demand
Estimate average daily water use based on household size and habits
Typical per-person water use averages help calculate total daily demand for treatment planning.
Select a system sized to accommodate peak flow and volume needs
The C-Series system is designed to handle residential demand levels, ensuring consistent pH adjustment without flow restriction.
Consider the frequency of filter media regeneration or replacement
Maintain system effectiveness by monitoring capacity relative to water hardness and volume treated over time.
Understanding the difference between area-based pH data and your home's specific water is critical for managing acidic water concerns. Use public records as a reference while testing your own water to guide treatment choices. The C-Series Acidic / Low-pH Water Filter provides a reliable method to stabilize water pH, preserving plumbing and improving water quality at the tap.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2024-08-05. 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 100SDGV aquifer (Washington County): 4 results from 1 wells, median 7.4 standard units, range 7.1-7.9 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 0 of 4 sampled results fell below 6.5
