Review of the Potential for the Proposed Expanded Taylorsville Road Hardfill Landfill to Pollute Huber Heights Domestic Water Supply

Huber Heights, Ohio, through its domestic water supply contractor, Earth Tech, has requested that I conduct an evaluation of the potential for an expanded Taylorsville Road Hardfill landfill to pollute the Rip Rap Road Well Field groundwaters that serve as the source for part of Huber Heights ’ domestic water supply. This review is to focus on the Impact Study report provided by Terran Corp. on behalf of the Taylorsville Road Hardfill landfill. I have reviewed the “Impact Study of Asphaltic Construction Debris on Groundwater Quality ” prepared by Terran Corp, dated August, 2002 as well as other documents provided to me by Earth Tech that are pertinent to evaluating the potential for the Taylorsville Road Hardfill landfill to release chemical constituents present in the landfilled wastes to the groundwater underlying the landfill that could be transported to the Huber Heights domestic water supply well field. I conclude that the Taylorsville Road Hardfill landfilled wastes are a significant threat to release pollutants that can be transported to the Huber Heights domestic water supply well field at sufficient concentrations to impair the use of the groundwaters pumped by this well field for domestic water supply
