CEDAR RAPIDS, Iowa — The City of Cedar Rapids says officials are closely monitoring the nitrate level in the Cedar River because it has reached one of the highest concentrations ever recorded.
The city blends river water with water from nearby wells to keep nitrate levels below the 10 milligrams per liter required by the Environmental Protection Agency.
Untreated river water is testing at 18.5 milligrams per liter. The city said its drinking water tests at 7.6. City officials must inform residents and state officials if it rises above the EPA limit.
Infants less than six months old could become seriously ill and die if they drink water above the EPA limit.
Many Iowa rivers have record nitrate levels, the result of recent heavy rain washing fertilizer from farm fields. — AP
