Well Water in Otsego County: What to Test and Why

Groundwater in Otsego County contains iron, arsenic, and chloride. Iron exceeds the EPA health standard, making it the main concern for well owners in this area.

Iron comes from minerals naturally locked in the bedrock beneath the county. As groundwater sits in contact with these rock layers over time, iron dissolves into the water. Arsenic also occurs naturally in the same rock formations, while chloride enters partly from road salt that seeps down through soil.

Groundwater in this county is moderately hard, driven mainly by elevated iron. Iron concentrates in the water because of the slow movement of groundwater through cracks in the underlying rock. These characteristics are common across wells throughout the county.

Iron exceeds EPA health standards in wells across Otsego County. Long-term exposure to elevated iron can harm your body's organs and systems over time. While iron is not an immediate poison, repeated exposure is a health concern worth addressing. Arsenic and chloride also appear in some county wells at lower levels.

Iron in county wells leaves orange or reddish-brown stains on sinks, toilets, and laundry. Your water may taste metallic or have an unpleasant odor. Iron buildup can also clog pipes and reduce water flow over time. These are quality-of-life problems that affect your daily use of water.

We recommend testing your well water to find out what is actually in it. Every well is different, and your well may have higher or lower iron levels than what is common in the county. Testing is the only way to know what needs treatment. A basic health screen runs fifty to one hundred dollars. An iron filtration system can remove iron and improve your water quality.
