• Abstract:
  This report represents the third and final phase of a three-part effort aimed at providing Sustainable Design Guidelines for ; Washington State Ferry terminals, specifically addressing the efficacy for removal of copper and zinc using a biobased filter media ; both in laboratory and field conditions. This work supplements previous reports that detail design concepts in implementation of ; stormwater strategies to be deployed on waterfront structures. The Bainbridge Island ferry terminal staging area was selected as ; the field test site. A pilot scale adsorption column and submersible weir system was designed and constructed to fit within an ; existing stormwater vault. Laboratory and field scale continuous flow column studies were performed on raw and torrefied ; Douglas-fir Crumbles® (Psuedotsuga menziesii), charcoal (also referred to as biochar), and pea gravel to evaluate their ; effectiveness for adsorbing soluble forms of copper and zinc. Laboratory column tests indicated that the most efficient adsorption ; for both copper and zinc was non-torrefied wood, followed in order by pea gravel, torrefied wood, and charcoal. Increasing ; influent column flow by a factor of four resulted in no statistically significant difference in effluent metal concentration. A deicer ; flush performed on torrefied wood and charcoal columns following adsorption tests resulted in over an order of magnitude increase ; in column effluent copper and zinc concentration, indicating that bypassing the filtration system during deicer runoff events should ; be considered.
