Well owners in Murray County should be aware of manganese, sulfate, iron, lead, arsenic, nitrate, and PFOA in the groundwater. These contaminants exceed EPA health standards and require attention.
The rock beneath this county naturally releases iron and manganese as water moves through it over time. Sulfate comes from the same geological source. Nitrate enters from agricultural activity--fertilizers and manure in the soil add nitrogen that seeps down. Lead and arsenic can come from both the rock and from older plumbing or contaminated areas. PFOA is a human-made chemical that has entered some wells through industrial or commercial sources.
Groundwater in this county is very hard, driven by elevated sulfate and iron. The underlying rock slowly dissolves minerals as water passes through, concentrating these elements in the water supply. Very hard water with high sulfate is widespread across wells throughout Murray County.
Wells in Murray County commonly contain lead, arsenic, iron, manganese, nitrate, and per- and polyfluoroalkyl substances (PFAS chemicals). Lead damages children's brain development and nervous systems. Arsenic increases the risk of cancer and harms kidneys and other organs. Nitrate is especially dangerous for infants and can affect oxygen in the blood. Manganese at high levels can harm the nervous system. These contaminants pose serious health risks and demand your attention.
The extremely hard water in this county will create visible problems in your home. You will see orange and brown staining on fixtures, laundry, and skin from iron. Scale builds up inside pipes, water heaters, and dishwashers, shortening their lifespan significantly. The high sulfate levels may give the water a bitter or unpleasant taste. Soap and shampoo will not work well, leaving you feeling like your clothes and skin are not clean.
We recommend getting your well tested with a comprehensive metals and minerals panel to find out exactly what is in your water, since every well in this county is different and yours could be higher or lower than average. Testing is the only way to know what treatment your specific well needs. A comprehensive panel typically costs $200 to $400. Treatment options like reverse osmosis systems or ion exchange can address multiple contaminants at once.

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.
