Well owners in Newport News need to be aware of chloride, iron, manganese, fluoride, nitrate, and sulfate in their groundwater. Several of these contaminants exceed EPA health standards, making testing and treatment important.
These contaminants come from the coastal plain geology and saltwater intrusion. The area sits near the ocean, and saltwater pushes inland into the underground layers where fresh groundwater sits. Iron and manganese dissolve naturally from the sediment and rock as water moves through the ground. Nitrate enters from fertilizer and septic systems in developed areas.
Groundwater in Newport News is notably high in sodium and contains moderate sulfate and iron. Sodium concentrates here because saltwater from nearby coastal areas mixes with fresh groundwater in the underground layers. These mineral and salt characteristics are widespread across wells in this city.
Wells in Newport News draw water from an aquifer that contains several contaminants exceeding EPA health standards. Chloride, fluoride, iron, manganese, nitrate, and sulfate show up in county well water above safe drinking levels. Exposure to these contaminants can damage your kidneys, bones, and nervous system over time. Nitrate is especially dangerous for infants and pregnant women.
The high sodium in Newport News wells creates a noticeable salty taste in drinking water and affects cooking. Iron leaves orange or reddish stains on laundry, dishes, and bathroom fixtures. Manganese can cause dark brown or black staining and may affect water taste and odor. These minerals also build up inside pipes and appliances, which shortens the lifespan of water heaters and dishwashers.
Your well is unique, and your water could have higher or lower levels than what is common here. Testing is the only way to know exactly what is in your well so you can treat it properly. We recommend a comprehensive metals and minerals panel to check all these analytes--this typically costs $200 to $400. Treatment options like reverse osmosis or ion exchange filters can remove many of these contaminants.

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.
