Groundwater in Livingston County contains iron, manganese, radon, arsenic, and chloride. Several of these contaminants exceed federal health standards, making testing urgent.
The Marshall aquifer rock naturally contains iron, manganese, and arsenic locked inside the stone. As groundwater moves slowly through this rock in low-oxygen conditions, these metals dissolve into the water. Chloride enters from road salt applied to highways and roads in the area.
Groundwater in this county is notably high in iron. Iron concentrates in the water because the sandstone rock releases it as water passes through slowly over time. Most wells in Livingston County show elevated iron levels, and these characteristics are common across the region.
Wells in Livingston County commonly contain arsenic, radon, chloride, iron, and manganese at levels above EPA health standards. Arsenic is a poison that builds up in your body over years of drinking it. Long-term exposure increases your risk of cancer, heart disease, and skin problems. Radon is a radioactive gas that enters water from natural rock decay. When you drink radon or use it in the shower, it can increase your lung cancer risk. Manganese can harm children's brain development and learning when consumed over time.
Wells in this county often have high iron, which causes orange or brown staining on sinks, toilets, and laundry. You may notice a metallic taste in the water or a rotten-egg smell from elevated levels of certain minerals. The combination of these minerals makes the water hard, which can leave crusty buildup on faucets and inside pipes and appliances.
We recommend testing your well water through a state-certified lab, since every well is different and yours may have higher or lower levels than what is common here. Testing is the only way to know what is actually in your water so you can treat it properly. Because multiple contaminants exceed health standards in this county, a comprehensive metals and minerals panel is recommended--these typically cost $200-400. Treatment options like reverse osmosis systems or arsenic-removal filters paired with water softeners can address multiple contaminants.

MCL = Maximum Contaminant Level (EPA limit for public water; used as benchmark for private wells). Distribution shows % of sampled wells in each concentration band. Methodology.
* Microbial contaminants (E. coli, coliform) reflect only samples from the last 10 years.
