Groundwater in Hampton contains chloride, iron, manganese, and sulfate at levels that exceed EPA health standards. These contaminant levels are high enough that well owners should test their water and consider treatment options.
The coastal plain geology here naturally contains salt and minerals left behind from ancient seawater. As fresh groundwater moves slowly through the sandy and clay layers underground, it dissolves these salts and minerals, concentrating them over time. Sulfate and iron also come from the rock itself, which contains iron-bearing materials that release these elements into the water.
Groundwater in Hampton is very high in sodium and sulfate, with elevated iron present as well. This salty, mineral-rich character comes from the coastal plain's geology, which was shaped by ancient ocean deposits and contains naturally high concentrations of these elements. These characteristics are common across wells throughout this area.
Wells in Hampton city commonly have chloride, iron, manganese, and sulfate at levels above EPA health standards. Chloride at high levels can raise blood pressure in people who are sensitive to salt. Iron and manganese can harm the brain and nervous system, especially in children and babies. Sulfate can cause digestive problems and dehydration, particularly in infants and people with certain health conditions.
County well water with these minerals causes real problems at home. High sodium and sulfate create a salty taste that makes water unpleasant to drink and cook with. Iron stains laundry, sinks, and fixtures orange or brown. The combination of these minerals creates scale buildup inside pipes and water heaters, which can shorten the lifespan of your appliances like dishwashers and hot water tanks.
We recommend getting a comprehensive water test right away since multiple contaminants exceed health standards in this county. Every well is different, and your well could have higher or lower levels than what is common here. Testing is the only way to know exactly what is in your water so you can treat it properly. A comprehensive metals and minerals panel typically costs between two hundred and four hundred dollars and will show you exactly what you're dealing with. Treatment options like reverse osmosis systems or ion exchange can remove many of these contaminants.
