Beginning Wednesday November 6th, UC Berkeley will implement the Western Transition Area and Bulb investigations as part of the 2017 Phase V Field Sampling Plan. This investigation will involve the excavation and backfilling of 38 potholes to determine the contents of the fill, sources of geophysical anomalies, as well as identify chemical concentrations in the soil of the Western Transition Area or "Bulb." Soil sample results from samples collected within the WTA will provide data to assess risk posed to human and ecological receptors, and the potential for fill contents to leach into the WSM and Meeker Slough. The work is expected to take five days, and will use a small excavator to complete the potholing.
All work is conducted under oversight by the DTSC, and by the campus Office of Environment, Health, & Safety (EH&S). Updates will be posted to this website. For any questions or more information, please contact EH&S at 510-642-3073 or ehs-ep@berkeley.edu.
