Well Water in Licking County: What to Test and Why

Manganese, iron, chloride, and sulfate are present in Licking County groundwater. Chloride, iron, manganese, and sulfate all exceed EPA health or secondary standards, marking concerning levels that require attention.

The rock beneath Licking County naturally contains these metals and minerals. As groundwater moves slowly through cracks and spaces in the bedrock, it dissolves iron and manganese directly from the stone. Chloride and sulfate leach from minerals in the deeper rock layers. These contaminants come straight from the geology--this is not pollution but natural dissolution.

Groundwater in Licking County is very hard, driven by elevated calcium and magnesium from the bedrock below. Iron dissolves naturally as water sits in contact with iron-bearing minerals in the rock. These characteristics are widespread across wells in this county.

Wells in Licking County commonly exceed EPA health standards for chloride, iron, manganese, and sulfate. Manganese at elevated levels can harm your brain and nervous system over time. Iron and chloride at high levels in drinking water create health concerns with long-term exposure. Sulfate also poses risks when present in excess amounts in your well.

County wells are extremely hard, which means white crusty scale builds up quickly inside pipes and on fixtures. The high iron content causes orange and brown staining on sinks, toilets, and laundry. Extreme hardness like this can shorten the lifespan of water heaters and dishwashers. Your water may also have a metallic or unpleasant taste from the mineral content.

We recommend testing your well with a comprehensive metals and minerals panel, since multiple contaminants exceed health standards in this county. Every well is different, and your water may have higher or lower levels than what is common here. Testing is the only way to know what is actually in your well so it can be properly treated. A comprehensive panel typically costs $200-400, and treatment options like water softeners combined with iron-removal systems can help address these concerns.
