Groundwater in Bertie County contains iron, arsenic, and chloride at levels that exceed EPA health standards. These contaminants are present in amounts serious enough that well owners should test their water and consider treatment.
Iron comes from the natural breakdown of rock in the aquifer system below your county. Arsenic and chloride also occur naturally in these underground layers, particularly in areas where saltwater has mixed with freshwater over time. The flat, coastal plain geology here concentrates these minerals as water moves slowly through sand and clay.
Groundwater in this county is soft, but iron at moderate levels is the main mineral character that stands out. Iron dissolves from the rock as water sits underground, and this mineral is widespread across wells throughout the county. Arsenic and chloride add to the water's composition, though they do not affect hardness the way calcium and magnesium do.
Wells in Bertie County have been found to exceed EPA health standards for arsenic and chloride. Arsenic exposure over time can damage your organs and increase cancer risk. Chloride at elevated levels can affect people with heart or kidney conditions. These contaminants in your drinking water deserve your attention and action.
The iron levels in county wells are moderate and can cause staining on fixtures, laundry, and dishes. You might notice a metallic taste or rust-colored water from the tap. The good news is that Bertie County's water is soft, so you won't face the scale buildup and shortened appliance lifespan that hard water causes in other areas.
We recommend testing your well with a comprehensive panel that includes arsenic, chloride, iron, and bacteria. Every well is different, and yours could have higher or lower levels than the county average. Testing is the only way to know what is actually in your water so you can treat it properly. A comprehensive metals and minerals panel typically costs $200 to $400 and will guide your next steps, whether that's installing an arsenic filter, reverse osmosis system, or other treatment.

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.
