    dct:description "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." ;
