NIVA har undersøkt forurensningstransporten fra Flåt nikkelgruve ved Evje fra november 1991 til august 1992. Nikkel var viktigste forurensningsparameter og total årlig transport var ca. 1.5 tonn/år. Viktigste forurensningskilde var øvre avgangsdam (60%), mens gruvevannet sto for ca. 20% av totaltransporten. Virkningen i Oddebekken er markert, men sur nedbør har antakelig større betydning for biologiske forhold i vassdraget.
