Government sampling of groundwater in Portage County's 100SDGV aquifer shows pH values ranging from 6.4 to 8.4 standard units with a median pH of 7.7, based on 123 results from 27 wells sampled between 2011 and 2024. None of these values fall outside the U.S. Environmental Protection Agency's secondary standard pH range of 6.5 to 8.5, which relates to water taste and potential corrosivity rather than health risk.
If you want to interpret what 'detected', 'median', and 'range' mean for this area's pH data
'Detected' means the pH was measured in each sample, never below the reporting limit. The 'median' pH of 7.7 suggests that half the samples are above and half below this value, indicating generally neutral to slightly basic water. The range from 6.4 to 8.4 shows some variability in water acidity and alkalinity in wells from 12 to 140 feet deep. However, only 2 of 123 samples fell below 6.5, slightly more acidic than the EPA secondary standard's lower aesthetic limit.
If you want to understand why aesthetic secondary standards differ from health-based limits for pH
The EPA’s pH secondary standard is not a health limit but focuses on water quality aspects such as taste, corrosiveness, and effects on plumbing. Water below 6.5 pH is more acidic and may be corrosive, which can gradually damage pipes and fixtures. Water above about 8.5 can lead to scaling. These effects influence household plumbing performance rather than causing direct health harm.
If you want to know how the Pentair Corrosive Water Damaging Pipes Filter addresses corrosive water
This Pentair System works by neutralizing water acidity through its filtration media, thereby reducing corrosivity. It modifies water chemistry to bring pH closer to neutral, lessening pipe damage and corrosion inside household plumbing. The system is shipped ready to configure, designed for residential use to protect pipes from acidic water effects typical in the region.
If you want to know the maintenance rhythm for the Pentair corrosive water filter
Routine care involves replacing the filtration media as specified by the manufacturer, generally after a defined period or water volume processed. This ensures consistent water quality adjustment without interruption. The system requires no special tools or professionals for upkeep, and all parts ship ready for straightforward user service.
If you want to understand how treated water differs at your tap after using the Pentair system
After treatment, the water has a stabilized pH closer to neutral, reducing acidity that causes corrosion. This results in diminished pipe wear, less metallic taste, reduced staining from corrosion minerals, and improved water clarity. Overall, household plumbing longevity is enhanced with fewer corrosion-related issues.
If you want to know which household fixtures and appliances are affected first by corrosive water
Fixtures and appliances exposed to continuous water flow, such as faucets, water heaters, and dishwashers, show corrosion effects earliest. Metal pipes and fixtures may develop pinhole leaks or mineral deposits. Treating water with the Pentair System protects these key points by balancing pH before water reaches them, preventing early damage and costly repairs.
For homeowners in Portage County noting signs of corrosive water or wishing to safeguard their pipes, testing your water’s pH is the crucial first step. The Pentair Corrosive Water Damaging Pipes Filter offers a proven, user-ready approach to neutralize acidic water detected in this aquifer, reducing pipe corrosion risks based on regional water chemistry data.

On record: U.S. Geological Survey sampling of pH in the 100SDGV aquifer (Portage County): 123 results from 27 wells, median 7.7 standard units, range 6.4-8.4 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 2 of 123 sampled results fell below 6.5
