All species chosen must be approved by the Corps of Engineers prior to testing. 



Whole sediment bioassays must include three (3) species: a crustacean (preferably 

 Ampelisca) . the polychaete Nereis, and a bivalve (preferably Macoma or Yoldia) . 



Bioaccumulation testing must use survivors of the bioassay (except Ampelisca) . including 

 the polychaete Nereis , a bivalve (preferably Macoma or Yoldia) . and Palaemonetes if it is 

 used in the whole sediment bioassay. 



This species may be used only if Ampelisca is unavailable. 



This species may be used only if Macoma or Yoldia are unavailable.
