Nitrate, iron, and fluoride are present in Shackelford County groundwater that well owners should know about. Iron and nitrate exceed EPA health standards in this county, making them a real concern.
Nitrate enters groundwater from fertilizers used on farmland and from septic systems in rural areas. Iron dissolves naturally from the rock layers underground as water moves through them. Fluoride also comes from minerals in the local rocks. All three contaminants are common in this region because the underlying rocks release iron and fluoride, while farming and rural development bring nitrate to the water.
Groundwater in this county contains elevated iron as its main mineral character, along with some fluoride naturally present in the rock. Water flowing through the local stone and soil dissolves these minerals into the groundwater. Most wells across the county show these characteristics to some degree, though the amount varies from well to well.
Wells in Shackelford County commonly contain iron and nitrate at levels that exceed EPA health standards. Nitrate is a concern for infants under six months old and can interfere with how their blood carries oxygen. Iron itself does not create health problems at the levels found in county wells, but it indicates your water has moved through certain rock layers that release minerals.
Water with elevated iron often leaves orange or rust-colored stains on sinks, bathtubs, and laundry. You may notice a metallic or unpleasant taste. These stains can be difficult to remove and build up over time on fixtures and in pipes.
We recommend testing your well water to find out what is actually in it, since every well is different and yours could have higher or lower levels than what is common here. A basic test for bacteria and nitrate costs around fifty to one hundred dollars, while a comprehensive metals and minerals panel runs two hundred to four hundred dollars. Iron removal filters or sediment filtration can help address these mineral concerns.

Test Your Well Water with Tap Score →| Contaminant | Samples ⓘ | % Above MCL ⓘ | Distribution ⓘ | Confidence ⓘ | Risk ⓘ |
|---|---|---|---|---|---|
| Nitrate | 3 | 33% | Low | High ⓘ | |
| Iron | 9 | 22% | Low | High ⓘ | |
| Fluoride | 131 | 0% | High | Low |
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.
