The site achieved national notoriety in L978, and thereaft'er, due to perceived human health iurpaãtÀ-i,o=-- residents located adjacent to Lt¡e site. The human health irnpacts are believed to be càused by the disposal of chenicãi wastes by the former Hooker chemical óorporatiðn (the ,ror owned by occidentat chenical corp.). The esti¡oãteã-äi,äéo-tons"orp-tty-i= of chenicat wastes disposed iir íove canãi-i;;i;ã";-ñ;;s orhers, chlorinated solventé, oirs, chlorouenãenes, hexachlorocycro_ l-ï11::, polychlorinared biphenyls (pcBt , and rrichlãrophenot (NYsDoH, 1981). Dioxins aré coñta¡nin"nts of trichlorophenol (Firestone, LgTz; Rappe et ar., 197gà)--and dibenzofurans are contaninants of pcB (Èowes et al., tgisa and 1975b) ãnd chlorophenols (Rappe et aI., Lg7gi.

The site has been encapsulated, arl known drainage terminated, a leachate collectioi anà treatment system installed, and homes most rikety to be irnpãôiea rrere destroyed. Remediation also included ðleaning-t,ñe-=ùrm water drai_nage syst'em and removing soils and sedir"it=--irãr'trr" cayuga creek basin (Black and Berqhortz creek) where 2,3;7,e-tcpo concentrations exceeded r.õ part per uittion. To evaruate the effectiveness of these rattei actions, a monitoiinj'progr", ,"" instituted which incorporat,ed fish as one cornponent. This latter study and its findings are reported here.
