Table 6. Summary of surrogate recoveries, Columbia River Basin, Washington and Oregon, 2008–10.


[Station names are shown in tables 2 and 3. Values reported in percent. Abbreviatons: ND, not determined because of matrix interferences or sample preparation errors; E, estimated; HCH, hexachlorocyclohexane; DDT, dichlorodiphenyltrichloroethane; PCB, polychlorinated biphenyl; NA, not analyzed, for example, currently used pesticides were not analyzed in 2008]
