	abstract = {The accumulation of organic contaminants in process-affected (PA) water represents an environmental liability for oil sandsoperators. Oil sands coke is a promising adsorbent for removing dissolved organic carbon (DO C), which includes toxic acid-extractableoil sands tailings organics (AEOSTO) found in PA water. The ability of raw and activated delayed and fluid coke to remove DOC andAEOSTO from PA water was assessed. Treatment with 5 g/L of activated delayed and fluid coke removed 91\% of DOC and 92\% ofAEOSTO at levels of 36 mg/L and 60 mg/L, respectively. Heavy metal leaching of vanadium at 5:9mg/L was observed for a 5 g/Lapplication of activated delayed coke, representing a challenge to the approach. Microtox testing indicated that higher carbon doses ofactivated cokes were effective in reducing toxic the biological response caused by organic compounds; however, exposure to heavy metalsincreased the toxic effect with time. The propos ed methodology should be coupled with an inorganic treatment technique for complete oilsands tailings water treatment. },
