A common misconception about corrosive water is that it always means dangerously low pH levels or an immediate health hazard. In Hendricks County, IN, based on U.S. Geological Survey groundwater data for aquifer 112PLSC, the water's pH values sampled from local wells fall well within the federal secondary standard for pH, which ranges from 6.5 to 8.5. This standard is designed to address water taste, staining, and corrosivity rather than health risk. Understanding this nuance is essential for households whose current water treatment is unable to fully protect plumbing from corrosion damage.
How to Interpret Certified Laboratory pH Test Results
Certified laboratory tests report pH as a standard unit value that quantifies acidity or alkalinity. For the 61 samples collected from five wells in Hendricks County between 2014 and 2025, pH ranged from 7.0 to 8.2, with a median of 7.8. These results indicate neutral to slightly alkaline conditions in the local aquifer. A pH below 6.5 would indicate acidic water likely to cause corrosion, but none of the samples fell below this threshold. Thus, a low pH corrosive condition is not broadly established by regional data alone. Residents should test their specific well or tap water to determine actual corrosivity at home before deciding on treatment steps.
How the C-Series System Neutralizes Corrosive Elements
The C-Series Corrosive Water Damaging Pipes Filter targets corrosivity factors that contribute to pipe degradation. It uses filtration and conditioning media designed to adjust water chemistry, stabilizing pH and reducing corrosive effects. This action helps protect metal plumbing by minimizing metal leaching and scaling. Because corrosivity can vary even within an aquifer, the C-Series system ships ready to configure to fit the household water demand and its unique chemistry profile, enhancing existing equipment that may be underperforming.
What Hendricks County pH Values Mean Against Federal Secondary Standards
The federal secondary standard for pH of 6.5–8.5 exists mainly to address aesthetic concerns and plumbing preservation. The USGS sampling shows Hendricks County aquifer waters are consistently within this range, suggesting that corrosive conditions are not widespread locally. However, secondary standards are advisory and do not define safety or health. The presence of any corrosivity should instead be confirmed by localized testing and by observing household plumbing effects, rather than relying solely on regional pH data.
Influence of Well and Sample Depth on Corrosive Water Profiles
The USGS samples were drawn from wells 8 to 28 feet deep. Shallow wells may be more influenced by surface activities, whereas deeper wells can have differing mineral content affecting pH and corrosiveness. Homeowners with wells outside this depth range or different source types should consider additional testing. Water corrosivity can fluctuate based on aquifer layers, seasonal changes, and local geology, underscoring the importance of site-specific analysis.
Plumbing Material and Age: Factors Beyond Source Water Chemistry
Even with water chemistry within recommended ranges, household plumbing materials and age can influence corrosion symptoms. Older pipes made of iron, steel, or copper may be more susceptible to corrosion, especially if protective coatings have worn. Plastic plumbing is generally unaffected by water corrosivity. Recognizing this distinction helps in identifying whether water treatment or plumbing updates are the best approach to mitigate corrosion damage.
For households in Hendricks County where existing equipment cannot keep pace with corrosive water demands, the C-Series Corrosive Water Damaging Pipes Filter offers a targeted solution. Designed to address the specific corrosivity conditions indicated by your measured water parameters and household use, the C-Series system ships ready to configure—providing enhanced protection to your plumbing infrastructure while complementing your current setup.

Source: USGS groundwater sampling. Sampled 2025-08-25. 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 112PLSC aquifer (Hendricks County): 61 results from 5 wells, median 7.8 standard units, range 7.0-8.2 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 0 of 61 sampled results fell below 6.5
