Induced polarization: a geophysical method for detecting metal contaminated ground water Item Info

Induced polarization (IP) is a useful geophysical method for investigating metal contaminated ground water. Laboratory experiments show zinc, copper, and lead contaminated ground water produce induced polarization and/or resistivity anomalies. Field testing at Smelterville Flats, Cataldo Flats, and Bunker Hill Flats East Tailings Pond in the Coeur d'Alene River Drainage in Northern Idaho demonstrates usefulness of the technique in field studies. The field sites are contaminated by controlled, uncontrolled, and abandoned mineral resource wastes, jig and flotation tailings. IP response is different in coarse sediments and wastes, clay sized wastes, and clay sized natural sediments; furthermore, IP and resistivity responses are affected by man made debris and saturation variations. The geologic complexity of the river deposited wastes and sediments has confounded many investigations at the Smelterville Flats site. Sediment and ground water contaminant concentrations interact in controlling IP response. Further laboratory experiments and field tests incorporating bore-hole control are recommended to fully develop the potential of induced polarization in remedial waste investigations.
