Testing in Union County shows no contaminants at levels that exceed health standards. Contaminant levels in this county's groundwater are low.
The surficial aquifer system here--made up of sand, gravel, and other loose materials near the surface--naturally resists contamination because water moves quickly through these materials and spreads out before harmful substances can build up. The sandy and gravelly soils in this area also filter out many pollutants before they reach the water table.
The mineral content of groundwater in Union County is not well documented through available testing data, so the exact character of your water depends on the specific rocks and soils beneath your well. Since this area's surficial aquifer taps into sandy and gravelly layers rather than limestone or iron-bearing rock, mineral levels are generally moderate across wells in the county.
Testing data for wells in Union County shows no contaminants detected at levels that exceed EPA health standards. This is good news for your water quality right now. However, county-level data represents what is common across many wells in the area, not what is in your specific well.
Mineral content information for county wells is not available, so we cannot tell you what aesthetic or quality-of-life impacts you might experience from your water. Different wells in the same county can have very different mineral levels and other characteristics.
We recommend that you get your well tested to know exactly what is in your water. Testing is the only way to understand your specific situation and determine if any treatment is needed. A basic screen for bacteria and nitrate runs about fifty to one hundred dollars and gives you a starting point for your well's water quality.

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.
