Groundwater in Panola County contains iron, chloride, manganese, fluoride, and lead. Several of these contaminants exceed EPA health standards, making them a concern for well owners in this area.
The Mississippi embayment aquifer system underlying this county naturally contains elevated minerals and salts from ancient rock layers deep underground. Iron and manganese come from the rock itself and become dissolved as water moves through it. Chloride and fluoride also occur naturally in these deeper layers. Human activities like oil and gas operations or salt intrusion in coastal areas can add to chloride levels.
Groundwater in this county is notably high in sodium, though not hard in the traditional sense. The rock layers here release sodium into the water over time as groundwater flows through them. High sodium is a widespread characteristic across wells throughout Panola County, and many residents encounter this trait in their water.
Wells in Panola County have been found to exceed EPA health standards for chloride, fluoride, iron, lead, and manganese. Lead exposure harms children's brain development and learning. Fluoride at high levels can cause bone and dental problems. Chloride, iron, and manganese at elevated levels pose risks to kidney function and can affect the nervous system, especially in infants and young children.
The high sodium content in county well water can leave a salty taste and make water unsuitable for people on salt-restricted diets. Iron in the water creates rust-colored staining on sinks, toilets, and laundry. Manganese causes brown or black stains and can leave a metallic taste in drinking water and beverages made with tap water.
Testing is the only way to know what is actually in your well so you can treat it properly. Since multiple analytes exceed standards in this county, we recommend a comprehensive panel that checks metals, minerals, bacteria, and nitrate, which typically costs between $200 and $400. Every well is different, and your well may have higher or lower levels than what is common here. Water softeners and iron filters or combination systems can help address these specific 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.
