The Big D Campground (Big D) site is located in Kingsville in Ashtabula County, Ohio. The area was originally a sand and gravel pit. From 1964 to 1976, wastes were dumped in the pit. The pit contained drummed hazardous wastes attributed to the Olin Corporation (Olin), the site’s potentially responsible party (PRP). Leachate from the site contaminated Conneaut Creek with chlorobenzene. Groundwater was contaminated with volatile organic compounds (VOCs) and heavy metals. Following cleanup, operation and maintenance activities are ongoing.
What Has Been Done to Clean Up the Site?
The site is being addressed through PRP actions under state and federal oversight.
EPA has conducted several five-year reviews of the site’s remedy. These reviews ensure that the remedies put in place protect public health and the environment, and function as intended by site decision documents. The most recent review concluded that response actions at the site are in accordance with the remedy selected by EPA and that the remedy continues to be protective of human health and the environment.The next scheduled review of the site’s remedy will take place in 2019.
What Is the Current Site Status?
The site’s long-term remedy included digging up all source material from the landfill and incinerating it on site, covering the former landfill, and pumping and treating groundwater on site. Eventually, some parts of the pump-and-treat system were no longer needed. They have been eliminated. At the request of the site’s PRP, a trial period is underway to see if monitored natural attenuation could be used in place of the pump-and-treat system. Natural attenuation describes a variety of in-place processes that, under favorable conditions, act without human intervention to reduce the mass, toxicity, mobility, volume or concentration of contaminants in groundwater.
