Data from the U.S. Geological Survey collected from August 2010 to October 2017 in Cumberland County’s aquifer 112ICCC shows a variation in groundwater pH levels, with 83 samples from 11 wells ranging from 4.0 to 7.6 standard units and a median of 6.2. Over half of these samples measure below the EPA’s secondary standard range of 6.5 to 8.5, indicating a tendency toward acidic, potentially corrosive water in this area.
Distinguishing Corrosive Water from Other Common Water Quality Issues
Corrosive water, characterized by a pH below the secondary standard minimum of 6.5, differs from other water problems such as hardness or sediment presence. While those primarily affect water clarity, scale formation, or sediment buildup, corrosive water directly influences the integrity of plumbing materials by accelerating metal corrosion. It is important to note that a measurement below EPA’s secondary standard is an aesthetic measure related to taste and plumbing concerns, not a health-based violation.
How Water Treated with the Autotrol System Differs at the Tap
When water exhibiting corrosive characteristics is passed through the Autotrol Corrosive Water Damaging Pipes Filter, the system works to stabilize pH and reduce the water’s corrosivity. The result is water that is less likely to degrade pipes and fixtures over time. Households can thus expect a reduction in corrosion-related issues such as metallic tastes, pipe leaks, or staining. The equipment ships ready to configure for household plumbing systems, providing a direct purchase solution without the need for professional intervention.
Meaning of 'Detected,' 'Median,' and 'Range' in the Local Sampling Record
In the USGS sampling record for this area, 'detected' means pH was measurable in each of the 83 sampled results, with none below the detection limit. The 'median' of 6.2 standard units represents the midpoint pH value when all samples are ordered, indicating a common condition in the aquifer. The 'range' from 4.0 up to 7.6 shows variability across different wells and sampling times, reflecting natural fluctuations rather than individual well conditions.
Comparing Cumberland County’s Corrosivity Record with Neighboring Areas
While Cumberland County’s median pH at 6.2 reveals a tendency toward acidic water, nearby counties may report different median and range values due to geological and hydrological differences. These regional variations do not imply that all wells in Cumberland County or neighboring counties behave uniformly. It’s essential to avoid overinterpreting the regional data as a universal condition for any specific household supply.
Steps to Evaluate Corrosive Water Issues in Your Home
- Start with simple visual inspections for pipe corrosion signs such as blue-green stains or leaks.
- Check for metallic taste or staining on fixtures.
- Conduct or obtain a laboratory test specifically measuring your water’s pH to understand its corrosivity precisely.
- Use the test results to decide whether treatment options like the Autotrol System would effectively address your water’s corrosivity.
The definitive way to confirm corrosive conditions in your household water is to order a laboratory analysis focusing on pH. Results showing persistent values below 6.5 standard units would support considering a treatment system designed to mitigate corrosive effects on plumbing.

On record: U.S. Geological Survey sampling of pH in the 112ICCC aquifer (Cumberland County): 83 results from 11 wells, median 6.2 standard units, range 4.0-7.6 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 53 of 83 sampled results fell below 6.5
