The findings come from the Utah Division of Water Quality.
Division assistant Director John Whitehead says the public needs to know about the contamination sites.
The EPA says mercury contamination is of concern when it reaches .03 milligrams per kilogram of fish. The rate is tied to chronic eating of mercury contaminated fish.
Utah sampling of nearly 12-hundred fish in 220 locations found 125 samples where mercury contamination was higher.
