Iron, manganese, and arsenic are present in groundwater throughout Lampasas County. All three exceed EPA health standards, which means they reach levels considered concerning for human health.
The rocks underlying this county naturally contain iron, manganese, and arsenic. Rainwater seeping underground dissolves these metals from the stone and carries them into the water supply.
Groundwater in this county is notably high in iron and manganese, the metals that give the water its character. These metals dissolve naturally from the rock as water moves through it underground. Iron and manganese show up in wells across the county, though levels vary from well to well.
Arsenic, iron, and manganese are found at levels that exceed EPA health standards in wells across Lampasas County. Arsenic can damage your organs over time and increase your risk of certain cancers. Iron and manganese can affect your digestive system and nervous system when consumed at elevated levels.
Wells in this county often have iron that creates reddish or brownish staining on fixtures, laundry, and plumbing. You may notice a metallic or unpleasant taste in your water. These minerals can also clog pipes and reduce water flow over time.
We recommend testing your well water with a comprehensive metals and minerals panel to find out exactly what you're dealing with. Every well is different, and your water could have higher or lower levels than what is common in the county. Testing is the only way to know what treatment your well needs--options include water softeners and iron filters.

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.
