PCBs measured in three tributaries of the Niagara River Area of Concern (AOC), 2018-2019

Water-borne polychlorinated biphenyls (PCBs) were sampled in three tributaries of the Niagara River Area of Concern (AOC) in 2018 and 2019 using semipermeable membrane devices (SPMDs). This data set is a compilation of data from two sampling efforts, focused on determining the presence and distribution of total and congener PCBs in these tributaries.
