Groundwater in Rains County contains nitrate, manganese, and PFOS, with iron and sulfate also present above EPA health standards. These levels are elevated enough that well owners should test their water and consider treatment options.
The contaminants come from several sources in the landscape. Nitrate typically enters groundwater from fertilizers and septic systems in areas with farming and rural homes. Manganese and iron occur naturally in the local rock and are released into water as it moves through the ground. PFOS comes from industrial use and has contaminated groundwater in scattered locations across the region.
Groundwater in this county is moderately hard and carries elevated sodium along with the iron and manganese from the underlying rock. The local geology naturally produces water with these mineral characteristics as rain seeps down through the soil and rock layers. Most wells in Rains County show these same mineral patterns, though the exact levels vary from well to well.
Wells in Rains County can contain iron, manganese, nitrate, PFOS, and sulfate at levels that exceed EPA health standards. Iron and manganese at high levels can cause problems with your blood and organs over time. Nitrate is especially concerning for babies and pregnant women, as it can interfere with how the body carries oxygen. PFOS is a chemical that builds up in your body and may affect your immune system and liver. Sulfate at elevated levels can cause digestive issues.
The minerals in county well water create everyday problems around your home. Iron stains laundry, sinks, and fixtures orange or brown, and it can make water taste metallic. Manganese leaves dark stains and affects taste as well. The moderately hard water here causes scale buildup on pipes and fixtures, which can shorten the life of water heaters and dishwashers over time. You might notice spots on dishes and soap that doesn't lather well.
Testing is the only way to know what is actually in your well, since every well is different and yours could have higher or lower levels than the county average. We recommend a comprehensive water panel that checks for metals, minerals, bacteria, and chemicals. A basic test runs $50 to $100, while a full panel costs $200 to $400. Treatment options like iron filters, reverse osmosis systems, or ion exchange softeners can address multiple concerns depending on what your test shows.

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.
