Well Water in Gloucester County: What to Test and Why

Groundwater in Gloucester County contains manganese, chloride, and iron at levels that exceed EPA health standards. These contaminant levels are notable enough that well owners should be aware of them.

The Northern Atlantic Coastal Plain aquifer system here is made of layers of sand, clay, and silt that naturally contain these minerals and salts. Saltwater from nearby coastal areas and brackish water can seep into the groundwater, which brings chloride. Iron and manganese come from the sediments themselves as water moves through them underground.

Groundwater in this county is moderately hard and carries elevated sodium along with iron and manganese from the sandy and clay layers in the aquifer. These minerals dissolve as water filters through the ground, and they concentrate in the water over time. Most wells in this county show this combination of characteristics.

Chloride, iron, and manganese are found at levels exceeding EPA health standards in wells throughout Gloucester County. Chloride at elevated levels can be harmful to people with high blood pressure or heart disease. Iron and manganese can affect how your body functions when consumed in drinking water over time. Testing your well is the best way to find out if these contaminants are present in your specific water.

Wells in this county often have moderately hard water, which can cause white scale buildup inside pipes and appliances. The very high sodium levels combined with the minerals in county groundwater may affect the taste and feel of your water. You might notice staining or a metallic flavor. Over time, moderately hard water can shorten the lifespan of water heaters and dishwashers.

We recommend testing your well water to find out what is actually in it, since every well is different and yours may have higher or lower levels than what is common in the county. A comprehensive metals and minerals panel typically costs between two hundred and four hundred dollars and will give you the full picture of your water quality. Water softeners and specialized filters can help address hardness and mineral concerns once you know your results.
