An illustration of an environmental dredge unit equipped with a 'deep suction
tube'.
(Please Note: A 'hydraulic agitator' [not shown here, but
see illustration of 'work implements' in the next panel below] can be attached
to the end of the deep suction tube. Further shielding can be attached
around the dredge 'head' to limit dispersion of PCB-contaminated particles.)
