| 摘 要： | Local water contamination by arsenic can be caused by gold mining activities as in Snow Lake, Manitoba. This project was to f＇md the source （s） and pathways of the arsenic contamination and describe arsenic attenuation in ground and surface water. The project was initiated because arsenic concentrations average 16.0 mg/L in one groundwater monitoring well （MW17）. One potential source of arsenic is the 50 year-old Arsenopyrite Residue Stockpile （ARS）, 100 m upgrade of MW17. Between 1948 and 1959, 250000 tons of cyanide treated, arsenopyrite concentrate were stored in a waste rock impoundment, which was left open until 2000 when it was capped with layers of waste rock, clay and silt to minimize water infiltration and the oxidative release of arsenic.
