Site History and Background:
Henryetta Iron and Metal operations consisted of acquiring an assortment of metal-containing objects from various sources for recycling. The property has been used as a metal salvage yard since the 1930s. Other businesses that have occupied the property include a blacksmith, motor freight lines, a welding facility, and a pipe and supply company. Electrical transformers containing Polychlorinated Biphenyls were reportedly recycled on-site beginning in the 1950s.
DEQ began its CERCLA site assessment in 2016 starting with the Preliminary Assessment. In 2017, DEQ completed a Site Inspection that included environmental sampling of nearby residential properties and Dutch Creek. In 2018, DEQ completed an Expanded Site Inspection that included environmental sampling of on-site soils and Dutch Creek. In 2019, DEQ collectected additional samples of on-site soils after EPA’s Removal Action was completed.
In 2010, EPA Emergency Removal and DEQ screened on-site drums and found radiation levels as high as 1.2 millirems per hour. The facility owner was then instructed to over-pack and secure for disposal.
In 2018, after DEQ found on-site contamination in nearby residential yards, EPA Emergency Removal conducted a removal action on affected residential properties and the city right-of-way. The removal action involved the removal of contaminated soils as well as the construction of an earthen berm, property contouring, and a fence to control future contamination migration back onto the remediated residential areas.
Sources of Contamination: Improper waste storage and disposal practices has contaminated soils on-site and Dutch Creek.
Contaminants of Concern: Polychlorinated Biphenyls, Metals, and PAHs
