Water in James City County often comes from aquifer 110QRNR, supplying private wells that tap into groundwater drawn from 2 to 29 feet deep. This groundwater's chemical balance, including its pH, can influence water behavior inside your home’s plumbing system.
If corrosive water remains unaddressed over years
Water with low pH—that is, acidic water—can gradually impact plumbing materials and fixtures. Over time, this may lead to increased pipe wear or metal dissolution, which could affect water taste and appearance but does not directly equate to health risk. Recognizing and managing corrosivity helps preserve plumbing integrity and maintain water quality.
If treated water reaches your tap using the Pentair Corrosive Water Damaging Pipes Filter
When this specialized filter is used, it is designed to reduce water corrosivity by adjusting pH and other factors influencing acidity. This results in water less likely to contribute to pipe wear and may improve the overall water experience. The Pentair System ships ready to configure and works as a direct purchase solution for household needs.
If considering the role of plumbing material and age
Corrosive effects partly depend on your home's plumbing. Older pipes or certain metals may react differently to acidic water than newer or corrosion-resistant materials. Plumbing condition can amplify or mitigate the impact of source water corrosivity, so understanding your system's characteristics is important.
If you are a commercial or industrial operator seeking more detailed information
Commercial or industrial water users might require additional testing and monitoring parameters beyond household scope, including corrosion rates and system-wide material assessments. These questions typically involve water chemistry complexities and regulatory requirements not usually relevant for residential households.
If you want context on how many samples and wells underlie these figures
The U.S. Geological Survey collected 141 pH results from 36 separate wells in James City County's aquifer 110QRNR between November 2017 and July 2021. This sampling size provides a reasonable representation of groundwater conditions in the area but does not define any individual well’s profile.
If you seek clarity on terms like 'detected,' 'median,' and 'range' in these results
The term 'detected' here means instruments measured pH at all 141 samples, with no below-reporting-limit results. The median pH value was 5.7 standard units, with an observed range from 3.7 to 7.1 standard units. These numbers describe the spread of acidity levels measured, where the Environmental Protection Agency’s secondary standard for aesthetic and corrosivity considerations is 6.5 to 8.5 standard units. Values below 6.5 indicate acidic or potentially corrosive water but are not health-based violations or safety limits.
This record reflects groundwater pH conditions from multiple wells sampled in James City County’s aquifer 110QRNR, as documented by the U.S. Geological Survey. More details are available at the government water data website for those who wish to explore further.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2021-07-21. 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 110QRNR aquifer (James City County): 141 results from 36 wells, median 5.7 standard units, range 3.7-7.1 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 120 of 141 sampled results fell below 6.5
