Well Water in Fayette County: What to Test and Why

Groundwater in Fayette County contains iron, manganese, and sulfate at levels that exceed EPA health standards. These contaminant levels are concerning and require your attention.

Iron and manganese dissolve naturally from the bedrock layers that sit beneath this county. As groundwater moves slowly through cracks and fractures in the rock, it picks up these metals over time. Sulfate also leaches out from minerals mixed into the same rock layers.

Groundwater in Fayette County is very hard, driven by elevated calcium and magnesium from the limestone bedrock below. The slow movement of water through this rock allows minerals to concentrate heavily in the water. These characteristics are widespread across wells throughout the county.

Wells in Fayette County commonly contain chloride, iron, manganese, and sulfate at levels that exceed EPA health standards. Chloride at high levels can raise blood pressure and harm people with heart disease. Manganese can affect brain development in children and damage the nervous system with long-term exposure. Iron and sulfate also pose health concerns when consumed regularly over time.

The water in this county is extremely hard, leaving thick white crusty buildup on pipes and fixtures. Iron stains sinks, toilets, and laundry orange-brown. The extreme hardness can shorten the lifespan of water heaters and dishwashers. You may also notice a metallic or rotten-egg taste from sulfate.

We recommend testing your well because every well is different and your water may have higher or lower levels than what is common in the county. Testing is the only way to know what is actually in your well so it can be properly treated. Since multiple analytes exceed health standards, a comprehensive metals and minerals panel is recommended and typically costs $200 to $400. Treatment options include water softeners combined with iron and manganese removal systems.
