Methyl mercury levels in Gruber=92s Grove Bay were found as high as 149
ug/kg (micrograms per kilogram) compared to an average concentration of 
4.7 ug/kg found in the Wisconsin River below Rhinelander.  The highest

level of methyl mercury previously found in the Wisconsin River was 8.1

ug/kg.  Gruber=92s Grove Bay is part of Lake Wisconsin, an impoundment of
the Wisconsin River.

I assume you are talking sediment concentrations here.  

Could you tell me:
1.  how many samples were taken in Gruber's Grove Bay and what the range
and mean were?
2.  Were any total mercury concentrations measured?  
3.  What were the concentrations measured in the fish?
