Westmoreland County groundwater contains iron, manganese, and fluoride above EPA health standards. These contaminants exceed safe drinking water limits and warrant attention from well owners.
The Northern Atlantic Coastal Plain aquifer system underlying this county is made of sandy and clay layers that naturally release iron and manganese as water moves through them. Fluoride also occurs naturally in these layers. These minerals dissolve into groundwater over time as it flows slowly through the rock and soil.
Groundwater in this county is soft, with elevated sodium as the main mineral character. Sodium concentrations are high in the water here because the sandy and clay layers of the coastal plain naturally contain salt deposits and saline minerals. High sodium shows up across many wells throughout the county, though individual wells vary in how much they contain.
Westmoreland County wells show fluoride, iron, and manganese at levels that exceed EPA health standards. Fluoride at high levels can damage developing teeth in children and affect bone health over time. Iron and manganese can cause serious problems with brain development and nervous system function, especially in infants and young children. These contaminants in your well water pose real health risks to your family.
The high sodium content in county groundwater is a concern for people on restricted diets and can affect your appliances and plumbing over the long term. You may notice a metallic or unpleasant taste in your water. The good news is that county water is naturally soft, so you won't deal with scale buildup or soap scum problems that plague harder water areas.
We recommend getting a comprehensive water test right away since multiple contaminants in your well exceed health standards. Your well may have higher or lower levels than what is common across the county, and testing is the only way to know what's actually in your water so you can treat it properly. A comprehensive metals and minerals panel costs between two hundred and four hundred dollars. Depending on your results, treatment options like filters, softeners, or reverse osmosis systems can remove these contaminants effectively.

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.
