Groundwater in Waynesboro contains arsenic, chloride, and bacteria from E. coli, but none of these contaminants exceed EPA health standards in the wells sampled, so levels here are low.
These contaminants enter groundwater through natural and human pathways. Arsenic and chloride occur naturally in the limestone and other rock layers beneath the city. Road salt and de-icing chemicals also add chloride to groundwater in urban areas. Bacteria like E. coli come from septic systems, sewage, or animal waste that seeps down through soil into the water below.
Groundwater in Waynesboro is moderately hard, driven by calcium and magnesium dissolving from the limestone bedrock. The carbonate rock that fills this region readily releases these minerals into water moving through fractures and pores. Moderate hardness is common across wells throughout the Valley and Ridge aquifer system in this part of Virginia.
Wells in Waynesboro show a pattern of concern with three contaminants that need attention: arsenic, chloride, and bacteria. Arsenic exposure over time raises the risk of cancer and can harm your kidneys and nervous system. Chloride at high levels can damage your kidneys and raise blood pressure. Bacteria like E. coli can cause serious stomach illness, especially in children and elderly family members.
The water in this county is moderately hard, which means you may see some white buildup on faucets and fixtures. Scale can form inside pipes and reduce water flow. You might notice spots on dishes after washing or feel a slight film on your skin. Hard water makes soap less effective for cleaning.
Testing your well is the only way to know what you actually have in your water since every well is different. We recommend getting a comprehensive panel that checks for metals, bacteria, and minerals so you understand your specific situation and can treat it properly. Testing costs between two hundred and four hundred dollars. Arsenic needs special filters, and bacteria requires disinfection like chlorination or ultraviolet 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.
