Groundwater in Somerset County contains manganese, iron, sulfate, lead, and nitrite--contaminants that exceed EPA health standards. These levels are concerning enough to require attention and testing.
The rock layers beneath Somerset County naturally contain iron and manganese that dissolve into groundwater as water moves slowly through cracks in the bedrock. Sulfate comes from minerals in these same rock formations. Lead and nitrite can enter from aged well infrastructure or nearby sources in the shallow subsurface.
Groundwater in this county is moderately hard, driven by elevated iron that concentrates naturally in the bedrock. Water moving through these ancient stone layers picks up minerals slowly over time, and these characteristics are common across wells in the county. Well owners should test their water to understand their specific conditions.
Wells in Somerset County commonly exceed EPA health standards for iron, lead, manganese, nitrite, and sulfate. Lead damages children's brains and nervous systems, even at low levels. Manganese harms brain development in children and can affect nervous system function in adults. Nitrite prevents blood from carrying oxygen properly, which is especially dangerous for infants. Iron and sulfate themselves are not health hazards, but the other contaminants in county wells pose real risks.
The moderately hard water in this county causes staining and scale buildup on pipes and fixtures. Iron creates reddish-brown stains on sinks, toilets, and laundry. White crusty deposits form inside water heaters and on faucets. Sulfate at these levels can give water a bitter or unpleasant taste.
We recommend testing your well water through a certified lab because every well is different and your water may have higher or lower levels than what is common in the county. Since multiple contaminants exceed health standards, a comprehensive metals panel is recommended. Testing typically costs between two hundred and four hundred dollars. Treatment options like iron removal systems combined with water softeners can address multiple concerns at once.

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.
