Well owners in Hardeman County need to know about chloride, sulfate, nitrate, iron, and manganese in their groundwater. Several of these contaminants exceed EPA health standards at concerning levels.
The rock beneath this county naturally contains these minerals and salts. As water moves through the underground layers, it dissolves chloride and sulfate from the rock itself. Nitrate comes from both natural sources in the soil and from agricultural activities on the land above.
Groundwater in Hardeman County is very hard, driven by extremely high levels of sodium and sulfate along with moderate iron. The underlying rock layers release these minerals as water passes through them over time. These mineral characteristics are widespread across wells throughout the county.
Wells in Hardeman County commonly exceed EPA health standards for chloride, iron, manganese, nitrate, and sulfate. Chloride at elevated levels can raise blood pressure in people who are salt-sensitive. Iron and manganese at these concentrations pose risks to infants and young children. Nitrate is especially dangerous for babies under six months old and can interfere with how blood carries oxygen. Sulfate can cause digestive problems including diarrhea and dehydration.
The extremely hard water in county wells creates significant quality-of-life challenges. You will likely see white scale buildup on faucets, shower heads, and inside pipes. Water may taste salty, bitter, or metallic. The very high mineral content can shorten the lifespan of water heaters, dishwashers, and other appliances. Staining and spotting on dishes and fixtures is common.
Your well is unique and could have higher or lower levels than what is typical for the county. Testing is the only way to know what is actually in your water so you can treat it properly. We recommend a comprehensive metals and minerals panel, which typically costs $200-400 and will measure all the problem analytes. Water softeners, reverse osmosis systems, or other specialized filters can address these concerns depending on your results.

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.
