The City of Arcata Wastewater Treatment Facility (AWTF) was issued a National Pollution Discharge Elimination System permit in 2019, which set a water quality objective for cyanide of 1.0 µg/L to protect saltwater ecosystems. Since enactment, the AWTF has exceeded the daily maximum effluent limit. This study used distillation and colorimetric analysis to investigate cyanide formation by comparing the cyanide levels in preserved and unpreserved samples taken concurrently with monitoring samples that were sent to a certified lab. Results found that found that unpreserved samples had no detectable levels of cyanide while preserved samples demonstrated a cyanide concentration of 0 to 1.7 µg/L.
