Groundwater in Luce County contains iron, lead, and arsenic. Iron and lead exceed EPA health standards, while arsenic is also detected and warrants awareness.
Iron in this county's groundwater comes directly from the Jacobsville aquifer rock itself. This sandstone contains iron minerals that dissolve into the water as it moves slowly through the stone. Lead and arsenic are also naturally present in trace amounts within this same rock layer. The combination of these three contaminants reflects the mineral composition of the aquifer that supplies wells across the county.
Groundwater in Luce County is notably high in iron. This iron comes from minerals locked inside the sandstone bedrock and dissolves as water passes through over time. The water is soft overall, so iron is the dominant mineral that shapes its character. Most wells in the county show elevated iron levels, making this a widespread characteristic of the local groundwater.
Iron and lead are found at levels exceeding EPA health standards in wells across Luce County. Iron exposure over time can cause stomach and digestive problems. Lead is especially dangerous for children and can affect brain development and learning. Both metals can build up in your body with long-term exposure.
The high iron levels in county wells leave orange and rust-colored stains on sinks, toilets, and laundry. You may notice a metallic taste in your water. The water here is relatively soft, so you won't see heavy white scale buildup like in other areas, but iron staining happens quickly and is hard to remove.
We recommend testing your well to find out what is actually in your water. Every well is different, and your well may have higher or lower levels than what is common in the county. Testing is the only way to know what needs treatment. A comprehensive metals panel typically costs $200-400 and will show exactly what you're dealing with so you can choose the right treatment, such as an iron filter or other removal system.
