No contaminants have been detected in Liberty County's groundwater at levels of health concern. Contaminant levels here are low.
The bedrock and soil in this area naturally filter water well. The rock underneath does not break down easily into minerals that would contaminate wells. Land use in the county also keeps pollution away from groundwater. Few industrial sites and limited urban development mean fewer sources of harmful substances entering the ground.
Based on the aquifer type in this county, groundwater here likely contains elevated calcium and magnesium from the rock below, making the water moderately hard. These minerals dissolve slowly from the bedrock as water moves through it. Hard water is common across wells throughout Liberty County.
The good news is that water samples from wells in Liberty County have not shown contamination exceeding EPA health standards. This means the county's groundwater is generally meeting federal safety requirements for the contaminants that are regularly tested.
Since mineral data for this county is limited, you may or may not notice water quality issues in your home. Some wells in the area could have iron or other minerals that cause staining, discoloration, or changes in taste or odor. Testing is the only way to find out what is actually coming from your well.
We recommend getting your well tested to know exactly what you're drinking. Every well is different, and yours could have different water quality than your neighbors. A basic screening for bacteria and nitrate costs around $50 to $100, while a more complete test runs $200 to $400. If testing finds iron or sediment, a filter system can help remove these particles.

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.
