Chemical history- No other chemical data from this site are known. 



Sediments. The sediment sample from WET66 exhibited a generally 

 enriched array of trace elements. Arsenic, boron, iron, and 

 vanadium concentrations ranked toward the upper end of ranges shown 

 for Rocky Mountain sites, with the arsenic concentration exceeded 

 only at mine-impacted or hypersaline sites. Only arsenic exceeded 

 the mean values for soils of the western United States (by a factor 

 of 5.5).
