Well Water in James City County: What to Test and Why

James City County's groundwater contains manganese, chloride, radon, iron, lead, and sulfate, with several reaching levels that exceed EPA health standards. The presence of these contaminants at concerning concentrations means well owners should test their water and consider treatment options.

These contaminants come from the county's sandy and layered underground rock. Manganese and iron occur naturally in this rock type and dissolve into water as it sits underground. Chloride and radon also occur naturally here, while lead can enter from old pipes and plumbing fixtures in homes. Saltwater intrusion from nearby coastal areas can raise chloride levels.

Groundwater in this county is moderately hard, driven by dissolved minerals including iron and sodium that accumulate as water moves through the sandy layers. This mineral character is common across wells throughout the county, though individual wells vary in what they contain.

Wells in James City County show elevated levels of chloride, iron, lead, manganese, radon, and sulfate above EPA health standards. Lead exposure harms children's brain development and learning ability, even at low levels. Radon is a radioactive gas that increases lung cancer risk over time. Manganese affects the nervous system and can cause movement problems with long-term exposure. Chloride and sulfate at high levels can cause digestive issues and other health concerns, especially for people on salt-restricted diets.

The moderate iron and hardness in county wells often leave reddish stains on fixtures, laundry, and dishes. You may notice a metallic taste or smell in your water. Hard water creates scale buildup in pipes and can shorten the lifespan of water heaters and dishwashers. Sodium levels are moderate but worth knowing about if anyone in your household needs to watch salt intake.

We recommend testing your well as soon as possible since every well is different and yours could have higher or lower levels than the county average. A comprehensive metals and minerals panel costs between two hundred and four hundred dollars and is the only way to know exactly what is in your water so you can treat it properly. Depending on your results, treatment options like reverse osmosis filters, ion exchange softeners, or radon removal systems can address your specific water quality issues.
