Groundwater in Delta County contains iron, arsenic, and fluoride. Iron levels here are at a moderate concentration that exceeds the EPA health standard, while arsenic and fluoride are present but at levels below what the EPA considers a health concern.
Iron comes from the natural rock and soil layers underground in this area. As water moves through these rocks over time, it dissolves iron and carries it into the groundwater. This is a natural process that happens across this whole region of northeast Texas.
Groundwater in Delta County is notable for elevated iron from the local rock layers. The combination of the rock type here and how water flows through it naturally releases iron into the water. Most wells in this county show some level of iron in their water.
Wells in Delta County commonly have iron at levels that exceed EPA health standards. Drinking water with too much iron can cause stomach problems and nausea. Iron can also make it harder for your body to absorb other nutrients you need. Over time, exposure to elevated iron may affect your overall health.
Iron in well water also causes staining on sinks, toilets, and laundry. Your water may look rusty or taste metallic. These stains can be hard to clean and may permanently discolor fixtures and clothes. The iron can also leave buildup in pipes and reduce water pressure over time.
We recommend testing your well water to find out exactly what is in it, since every well is different and yours may have higher or lower levels than others in the county. Testing is the only way to know what you are really dealing with so you can treat it properly. We suggest a comprehensive panel that checks for metals and minerals, which typically costs between two hundred and four hundred dollars. Iron can often be removed with a filter or by using an iron removal system.

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.
