Groundwater in Jackson County contains PFOA-related chemicals known as HFPO-DA, PFBS, and PFHXS. Contaminant levels in this county are low and do not exceed EPA health standards.
These chemicals come from human activity rather than natural sources. They enter groundwater through industrial discharge, firefighting foam at airports or military sites, and contaminated runoff. The crystalline rock that makes up the county's aquifer does not naturally produce these substances, so their presence points to land-based sources.
Groundwater in this county is soft, with low mineral content typical of crystalline rock aquifers. Water flowing through granite and similar hard rock does not dissolve large amounts of calcium, magnesium, or iron the way it does through limestone. This soft-water character is common across wells throughout the county.
Wells in Jackson County show some concern for certain chemicals called PFOA-like compounds. These substances accumulate in the body over long periods and can affect the liver, thyroid, and immune system. They are separate from bacteria or metals and require specific testing to detect.
The good news is that Jackson County wells generally do not show major mineral problems that cause staining, scale buildup, or taste issues. Your water quality for everyday use should be decent without the typical hard water complaints or orange stains that some areas experience.
We recommend testing your well water to find out what is actually present in your specific supply. Every well is different, and yours could have higher or lower levels than what is common in the county. A comprehensive panel that checks for these special chemicals costs between two hundred and four hundred dollars and is the only way to know if treatment is needed. If these compounds are found, specialized filters can remove them from your water.

MCL = Maximum Contaminant Level (EPA limit for public water; used as benchmark for private wells). Distribution shows % of sampled wells in each concentration band. Methodology.
* Microbial contaminants (E. coli, coliform) reflect only samples from the last 10 years.
