trace elements or micronutrients were included in this analysis. 

 Generally, the rapid flux of water through this site implied by the 

 moist climatic setting and high catchment to wetland ratio would 

 be expected to maintain dilute water chemistry. 



Sediments. The extractable arsenic concentration reported for LaFoe 

 Lake is one of the lowest for the entire data set. Boron, iron, 

 selenium and zinc concentrations rank raid-range among Rocky 

 Mountain sites. Most other trace elements were below detection 

 limits. 



The selenium concentration reported exceeded the mean value for 

 soils and other surficial materials of the western U.S. by a factor 

 of 1.7; other reported values were below their regional soil means.
