Groundwater in Greensville County contains arsenic, chloride, and fecal coliform. None of these contaminants exceed EPA health standards in this county, so levels are low.
Arsenic and chloride come from the sand and clay layers that make up the aquifer system here. These are natural minerals that dissolve slowly as water moves through the ground. Fecal coliform bacteria can enter groundwater from surface sources like septic systems or animal waste, especially where the aquifer is shallow or has cracks that reach the surface.
Groundwater in Greensville County is very hard, driven by elevated calcium and magnesium dissolved from minerals in the sand and clay layers. Water stays underground long enough to pick up these dissolved minerals before reaching your well. Very hard water is common across most wells in this county.
No analytes exceed EPA health standards in Greensville County wells based on current county-level data. However, arsenic and chloride are contaminants of concern found in groundwater here and warrant attention. Arsenic can damage organs and increase cancer risk with long-term exposure. Chloride at elevated levels can be harmful to people on sodium-restricted diets and may indicate saltwater contamination of the aquifer.
Wells in this county have very hard water, which means you will see scale buildup on faucets and fixtures, reduced lather from soap, and reduced efficiency of cleaning products. Hard water can shorten the lifespan of water heaters, dishwashers, and washing machines. You may notice a chalky or mineral taste in the water. Sodium levels are moderate, so that is less of a concern for most households.
We recommend testing your well with a comprehensive metals and minerals panel to learn what contaminants are actually present in your water. Your well may have higher or lower levels than what is common in the county--testing is the only way to know. A full panel typically costs between $200 and $400. Treatment options like arsenic removal systems or water softeners can address specific problems once you have results.

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.
