Groundwater in Foard County contains sulfate, nitrate, chloride, and fluoride. Several of these show elevated levels that exceed EPA health standards, with sulfate reaching very high concentrations.
The rock formations under Foard County naturally contain these dissolved minerals. Sulfate and chloride leach into groundwater as water moves through the rock layers. Nitrate can come from soil and fertilizer as water filters down from the land surface, especially in farming areas. Fluoride occurs naturally in some rock types in this region.
Groundwater in Foard County is notably sulfur-bearing, driven by very high sulfate levels from the surrounding rock. The underlying geology in this area naturally releases sulfate as groundwater passes through. These mineral characteristics are common across wells throughout the county.
Wells in Foard County have been found to exceed EPA health standards for chloride, fluoride, iron, nitrate, and sulfate. Chloride at high levels can raise blood pressure in people who are sensitive to salt. Fluoride in excess amounts can cause dental problems, especially in children. Nitrate is dangerous for babies and can affect how blood carries oxygen. Sulfate can cause digestive issues and diarrhea in some people.
The very high sulfate levels in county well water create strong taste and odor problems that most people notice right away. Sulfate can make water taste bitter or like rotten eggs and leave stains on fixtures and laundry. Even though iron levels are low in this county overall, any iron present can still cause brown staining on sinks and clothes and leave a metallic taste in drinking water.
We recommend that you test your well water with a comprehensive panel since multiple contaminants exceed health standards in this county. Every well is different, and your water could have higher or lower levels than what is common here. Testing is the only way to know what is actually in your well so you can decide on proper treatment. A comprehensive metals and minerals panel typically costs between two hundred and four hundred dollars, and treatment options like reverse osmosis systems or water softeners can address multiple concerns.

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.
