The Flying M Ranch is located in Mineral County, Nevada and was owned by the Hilton & Ryland Realty Estate. The owner and buyer had executed a sales agreement that required the remediation of a historical livestock dip facility. The facility used toxaphene, a pesticide to treat animals for the infestation of ectoparasites, such as ticks, fleas and mites. The facility was comprised of corrals and a dip trough filled with a toxaphene solution to immerse the animals. The soils in the facilities immediate area were contaminated with toxaphene, a recognized hazardous substance and potential hazardous waste.
