Ecological Risk Assessment,
Lake Waban, Massachusetts

Woods Hole Group provided quarterly sampling and analysis of surface water, sediment and tissues in support of an ecological risk assessment.  Surface water metals were sampled and analyzed using “clean” techniques, i.e., Class 100 clean hood conditions, according to Method 1669.  Additional water analyses included cyanide, hexavalent chromium, total suspended solids and hardness.  Sediments were analyzed for metals, physiologically available cyanide (PACN), hexavalent chromium and acid volatile sulfide/simultaneously extractable metals (AVS/SEM).  Fish tissue, mussels, clams, invertebrates and aquatic plants were analyzed for metals.  The fish species included large mouth bass, pumpkinseed sunfish and yellow perch.  Fish tissue analyses were conducted on whole body, fillets, and livers.  Various species of aquatic plants were analyzed either as stem/leaf or root samples.
