Well Water in Newaygo County: What to Test and Why

Iron, PFOA, and arsenic are present in Newaygo County's groundwater. Iron and PFOA exceed EPA health standards, while arsenic is detected but at levels below the threshold of concern.

These contaminants come from the rock beneath the county. Iron dissolves naturally as groundwater moves through iron-bearing minerals in the bedrock. PFOA likely enters groundwater through historical industrial or commercial activity, as this compound persists in the environment and moves through soil layers. Arsenic also occurs naturally in certain minerals in the rock.

Groundwater in this county is high in iron, which gives the water its mineral character. Iron dissolves from the rock as water sits underground and moves slowly through the aquifer layers. This elevated iron is common across wells in the county.

Wells in Newaygo County commonly contain iron and PFOA at levels that exceed EPA health standards. Iron at elevated concentrations can affect your blood and organs over time. PFOA is a manufactured chemical that can harm your liver, thyroid, and immune system with long-term exposure. Arsenic is also detected in some county wells and poses serious health risks from prolonged drinking water exposure.

Beyond health concerns, the iron in county wells causes practical problems in daily life. You may see orange or brown staining on sinks, toilets, and laundry. Iron can also clog pipes and damage appliances like water heaters over time. The mineral levels in this county are moderate overall, so aesthetic impacts depend on your individual well.

Every well in this county is different, and your well may have higher or lower levels than what is common here. Testing is the only way to know exactly what is in your water so you can treat it properly. We recommend a comprehensive metals and minerals panel to check for all contaminants; this typically costs $200-400. Iron removal filters or whole-house filtration systems can address iron concerns once testing confirms your levels.
