Leviathan Mine Pond 1, located near Markleeville, California, is a historical mining site that was designated a Superfund site in 2000 due to high concentrations of toxic heavy metals in the water. Hydrology studies have shown that the pond is connected to several springs and creeks in the area, which can transport the contaminated water downstream. Surface flow from surrounding hills and snowpack melting contribute to the pond's water source, which is treated to remove toxic metals before being discharged. The area around the pond is primarily used for cattle grazing, and there are no recreational activities permitted due to potential exposure to toxic materials. Ongoing remediation efforts are being undertaken to reduce the environmental impact of the mine and restore the natural ecosystem.
