This week, you need to evaluate how corrosive your household water might be based on local groundwater data and decide whether further testing or treatment is necessary.
1. How Well Depth and Source Affect Regional Water pH Expectations
The U.S. Geological Survey sampled groundwater from aquifer 112SRFD in Washington County between 2011 and 2019, measuring pH levels at depths of 72 to 95 feet. These samples provide a regional perspective but do not directly represent your household well or tap water. The median pH was 6.1 standard units, with most results ranging from 5.9 to 7.0. Note that a pH below the EPA’s secondary standard lower bound of 6.5 suggests a tendency toward acidity, which can contribute to corrosion in plumbing materials.
2. What Changes When the C-Series Corrosive Water Damaging Pipes Filter Is Used
Water treated with the C-Series system will have its corrosive characteristics reduced, protecting pipes and fixtures from damage caused by acidic water. Although the regional data shows frequent pH values below 6.5, applying this technology can help stabilize water chemistry at the tap, mitigating issues like pipe corrosion, metallic tastes, and surface staining that acidic water can cause.
3. Understanding a Certified Laboratory pH Test and Its Implications
A certified laboratory test measures your household water’s pH on a scale from 0 to 14, with lower values indicating acidity. Reading your water’s pH will show how corrosive your water may be compared to local groundwater samples. Since regional samples demonstrate a range, your own water’s pH could be higher or lower; only a test of your water will confirm its condition. Keep in mind, pH is not a health-based measurement but an aesthetic and material compatibility indicator.
4. Sample Size and Well Count Behind Regional pH Data and Its Interpretation
The regional data from Washington County is based on 12 pH results collected from two separate wells over multiple years. This relatively small sample size suggests some variability and seasonal or temporal changes might exist beyond this snapshot. While useful as a general guide, it cannot replace analyzing your specific water source to determine corrosion risk accurately.
5. Household Signs That Suggest Corrosive Water and Those That Do Not
- Potential Corrosive Water Indicators: Premature pipe deterioration, pinhole leaks, metallic or sour taste in water, blue-green stains on fixtures, or discoloration of plumbing materials.
- Signs Unrelated to Corrosive Water: Cloudy or turbid water, taste or odor issues caused by other contaminants, or health-related water quality problems that require different testing.
To resolve uncertainty about corrosive water in your home, order a comprehensive pH test from a certified laboratory. A pH result consistently below 6.5 standard units would confirm acidic conditions similar to those found in regional samples and support considering a treatment solution such as the C-Series Corrosive Water Damaging Pipes Filter to protect your plumbing system.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2019-09-17. 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 112SRFD aquifer (Washington County): 12 results from 2 wells, median 6.1 standard units, range 5.9-7.0 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 10 of 12 sampled results fell below 6.5
