Groundwater in Live Oak County contains arsenic, iron, and nitrate at levels that exceed EPA health standards. These contaminant levels are serious enough to warrant attention from well owners.
Arsenic and iron occur naturally in the rock layers beneath this county. Nitrate seeps down from agricultural activities and septic systems on the land above. The combination of these natural minerals in the local rock and human activities on the surface creates the contamination pattern seen here.
Groundwater in this county is notable for moderate iron content. Iron dissolves naturally from the rock as water moves through it underground. This characteristic shows up across many wells in the area, though individual wells vary in their iron levels.
Arsenic, iron, manganese, and nitrate show up at elevated levels in wells across Live Oak County. Arsenic can damage your kidneys and increase cancer risk with long-term exposure. Manganese can affect your nervous system development and function. Nitrate is a particular concern for infants and can cause serious health problems in young babies. Iron and manganese themselves are not health hazards at the levels found here, but they affect water quality.
Iron in county wells creates rust-colored stains on laundry, dishes, and plumbing fixtures. You may notice a metallic or unpleasant taste in your water. These minerals can build up inside pipes and water heaters over time. The staining and discoloration are the main quality-of-life issues well owners report in this area.
We recommend testing your well with a comprehensive metals and minerals panel to find out exactly what you are dealing with. Every well is different, and your well may have higher or lower levels than what is common across the county. Testing is the only way to know what is actually in your water so you can treat it properly. A comprehensive panel typically costs between two hundred and four hundred dollars. Treatment options like iron filters or reverse osmosis systems 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.
