Abstract
The surface waters of Moon Creek and the lower Coeur d'Alene River were sampled to investigate the fate of metals from mine waste. Most metals entering Moon Creek originate from a seep discharging acidic, metal-laden ground water. A mass balance constructed for the seep area was solved using a conservative-nonconservative pair of elements (Al-Zn). Concurrent with the precipitation of Al and Fe hydroxides, transition metals are scavenged in the following order: Pb much greater than Cu greater than Mn greater than Zn equal to Cd. Geochemical modeling indicates that this scavenging is not a result of transition metal precipitation. Adsorption modeling onto Al and Fe hydroxides is consistent with observed trends.
