Sediments. Arsenic, copper, selenium, vanadium and zinc were 

 reported in concentrations above detection limits. Copper and 

 selenium concentrations ranked toward the top for sample sites in 

 this class, while arsenic, vanadium and zinc concentrations ranked 

 near mid-range for their classification. Selenium exceeded the 

 mean soil concentration for the western U.S. by a factor of two, 

 copper by a factor of 1.5 and zinc by a negligible amount.
