AbstractUnderstanding the behaviour of arsenic in natural waters is important because arsenic and its compounds are toxic to humans and aquatic organisms. The Cobalt area, once renowned for its bonanza silver deposits, is now characterized by numerous deposits of arsenic-rich tailings, waste rock piles and remnant historic mine workings. Very limited mitigation has been undertaken since the cessation of mining. Thus, despite its slightly alkaline character, the surface drainage system continues to be contaminated from leaching of the widespread mine wastes. This Open File documents the transport and attenuation of arsenic and associated elements in the surficial environment from mine wastes (tailings and waste rock) through surface waters to wetlands of the Farr Creek drainage basin in Cobalt, Ontario.
