Groundwater in Prince George County contains manganese, radon, 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 options.
Manganese and radon occur naturally in the sandy and clay layers beneath the county. Chloride can come from road salt, fertilizers, or salty groundwater that moves upward from deeper layers in the coastal plain. The combination of these sources means contamination builds up in the water as it sits underground.
Groundwater in this county is soft with low iron and sulfate, which means it stays relatively clean in terms of minerals. The sandy geology of the coastal plain does not hold onto hard minerals like calcium and magnesium the way limestone does. Most wells here show this same soft, clean mineral character, though the presence of manganese and radon requires attention from well owners.
Wells in Prince George County can have chloride, manganese, and radon at levels above EPA health standards. Chloride at high levels can affect people with heart or kidney problems. Manganese exposure over time can damage the nervous system and cause learning problems in children. Radon is a radioactive gas that increases the risk of lung cancer when breathed in over many years.
The good news is that the minerals in county wells are generally low, so staining, scale buildup, and taste problems are not common concerns here. Your water heater and dishwasher should not experience shortened lifespans from mineral buildup. Most families in this area do not report aesthetic water quality issues.
We recommend testing your well to find out what is actually in your water, since every well is different and yours could have higher or lower levels than the county average. A comprehensive test for metals and radon runs between $200 and $400 and will show exactly what you are dealing with. Testing is the only way to know if treatment is needed, and options like carbon filters or radon ventilation systems can address specific problems.

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.
