Groundwater in Lincoln County contains chloride and fluoride as detectable contaminants. Contaminant levels in this county are low and do not exceed EPA health standards.
The crystalline rock beneath Lincoln County naturally breaks down and releases these minerals into groundwater over time. Chloride comes from weathering of the rock itself. The local geology and land use keep contamination low, so well owners face minimal health concerns from the water supply.
Groundwater in this county is soft, with low hardness and minimal mineral content overall. The crystalline rock underneath produces water that is naturally low in calcium and magnesium, the minerals that make water hard. Soft water with low mineral levels is the common character across wells in Lincoln County.
Good news: no contaminants in Lincoln County wells exceed EPA health standards. The county's groundwater is generally clean from a health perspective, which means you don't face known risks from bacteria, nitrates, or other regulated harmful substances at dangerous levels.
Wells in this county tend to be soft, so you won't see heavy scale buildup on fixtures or inside appliances. Your water should taste relatively clean without mineral flavors, and you shouldn't notice staining or odors from mineral content. Soft water is actually easier on your plumbing and appliances.
We recommend testing your well water anyway, since every well is different and yours could have higher or lower levels than what's common in the county. Testing is the only way to know what's actually in your water so you can treat it if needed. A basic screening costs around fifty to one hundred dollars and checks for bacteria and nitrate, which gives you peace of mind about your specific well.

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.
