Update on Workplan for Soil Sampling
A workplan for soil sampling was developed by WSP Global, Inc., an internationally recognized environmental consulting company with local offices. The workplan has been reviewed by the City and the Ohio EPA.
The workplan outlines soil sampling, which includes gathering representative soil samples to analyze for previously identified inorganic materials, anions, and other substances. These samples will be gathered through a series of soil borings and surface wipe samples in and around the battery testing areas: the testing room; testing pad; and the gravel storage area. All locations are on City-owned property; no residents or businesses will be inconvenienced by this work. The work will begin later this month (January 2024) and is expected to be completed within four to six weeks. The workplan and results will be shared with the community upon completion of the work.
Recap of Previously Completed Testing and Sampling of Conditions at the Former Water Plant
As we’ve reported earlier in this space, last fall, with input from Ohio EPA, the City of Piqua contracted with a third-party independent contractor for sampling and a certified laboratory to test the City’s water sources and treated water supply. The sampling results from the City's drinking water plant confirmed the water is safe for drinking, bathing, and cooking; and results from sampling of source waters in the area show there are no concerning contamination levels.
