Groundwater in Shackelford County contains nitrate and iron at levels high enough to exceed EPA health standards, and fluoride is also present. These contaminants are at concerning levels that warrant attention for private well owners in this area.
Nitrate comes from fertilizers and animal waste that seep down through soil into groundwater, while iron dissolves naturally from the rock layers below. The "other rocks" that make up this area's water-bearing zones release iron over time as groundwater flows through them, and agricultural activity in this region adds nitrate to the supply.
Groundwater in this county is notable for containing elevated iron from the rock formations below. Iron dissolves into water as it moves through the subsurface and concentrates in the groundwater supplies here. This mineral character is common across wells throughout the county.
Wells in Shackelford County commonly have iron and nitrate at levels above EPA health standards. Iron at high levels can cause problems with your blood's ability to carry oxygen. Nitrate is especially dangerous for babies and can interfere with how their blood works. Both of these contaminants need attention if they show up in your well.
Iron in county well water often leaves orange or brown stains on sinks, toilets, and laundry. It can make water taste metallic or create an unpleasant odor. These stains are hard to remove and can build up over time on pipes and fixtures.
We recommend testing your well water to know what you are actually dealing with. Every well is different, and your water could have higher or lower levels than what is common around here. Since multiple contaminants are a concern in this county, a comprehensive metals and minerals panel is worth considering, which typically costs between $200 and $400. Iron filters or nitrate removal systems can help treat these problems once you know your levels.

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.
