Groundwater in Echols County contains arsenic, chloride, and fluoride. All three are detected at levels below EPA health standards, so contaminant levels here are low.
These contaminants come from natural sources in the sandy and gravelly layers that make up the surficial aquifer system in this area. Arsenic and fluoride occur naturally in the rock and soil; chloride enters from saltwater influence in the deeper layers and from natural mineral deposits. The shallow aquifer's loose, sandy composition allows some minerals to dissolve into the water as it flows through.
Groundwater in this county is moderately hard, driven by calcium and magnesium from the sandy and gravelly rocks below. These minerals dissolve slowly from the aquifer materials as water moves through them. Moderate hardness is common across most wells in the county.
Wells in Echols County don't show contaminants exceeding EPA health limits right now. However, arsenic, chloride, and fluoride are present in county groundwater and worth monitoring. Arsenic exposure over time can increase cancer risk and cause skin problems. Chloride and fluoride at elevated levels can affect bone health and kidney function.
County wells have moderately hard water, which means you might see some scale buildup in pipes and on fixtures. Hard water can make soap less effective and may leave spots on dishes and glassware. Over time, moderately hard water can shorten the life of water heaters and other appliances by creating mineral deposits inside them.
We recommend testing your well water to find out exactly what you have. Every well in this county is different, and your water could have higher or lower levels of these contaminants than what we see across the county overall. Testing is the only way to know what needs treatment in your specific well. A comprehensive panel costs between $200 and $400 and can check for metals, minerals, and other concerns. Water softeners or reverse osmosis systems can help address hardness and certain contaminants.

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.
