Groundwater in Trumbull County contains manganese, iron, and PFOS along with chloride, sulfate, and other compounds that exceed EPA health standards. These levels are concerning and warrant testing and treatment.
The fractured rock layers beneath this county naturally release iron and manganese as groundwater sits in contact with the stone. Road salt spread on winter roads adds chloride, while sulfate dissolves from minerals within the bedrock. PFOS and related compounds come from industrial sources and have accumulated in some wells.
Groundwater in this county is hard, with elevated calcium and magnesium from the rock below. Iron and manganese add to this hardness and are common across wells in the area. The combination of hard water minerals, moderate iron levels, and sulfate create noticeable mineral character throughout the county.
Wells in Trumbull County commonly contain several contaminants that exceed EPA health standards. Chloride, iron, manganese, and sulfate are minerals found at unsafe levels in many county wells. PFOA and PFOS are human-made chemicals linked to serious health problems including kidney damage, thyroid disease, and cancer. Manganese can harm brain development and nervous system function, especially in children. Iron and chloride at high levels contribute to other health concerns over time.
Wells in this county are very hard, and the combination of minerals creates noticeable everyday problems. Iron leaves orange and reddish-brown stains on sinks, toilets, and laundry. The water may taste metallic or bitter. Sulfate can give water an unpleasant taste or smell. Extremely hard water can shorten the lifespan of water heaters, dishwashers, and other appliances due to scale buildup on pipes and fixtures.
We recommend testing your well as soon as possible. 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 is actually in your water so it can be properly treated. Since multiple analytes exceed standards, a comprehensive metals and minerals panel is recommended, which typically costs $200-400. A water softener combined with a filtration system can address hardness and remove harmful contaminants.
