Bhate performed a Remedial Investigation (RI) at two former landfills at Forbes Field, Topeka, Kansas for USACE/Kansas City under the Formerly Used Defense Sites (FUDS) program. The objectives of the RI were to characterize the extent and magnitude of contamination in groundwater, surface water, soil, sediments, and other matrixes, which may pose a threat to human health and/or the environment. As part of the RI, Bhate reviewed the results of the previous investigations and developed a work plan to accomplish the project objectives. Fieldwork consisted of shallow, intermediate, and deep monitoring well installation and groundwater sampling, Geoprobe soil sampling, geophysical logging, discrete interval packer testing, surface water and sediment sampling, surveying, and data validation/ERPIMS.

A Baseline Risk Assessment (BLRA) was performed to identify Contaminants of Concern (COCs) and the need for additional sampling. Based on these results, a second phase of investigations was completed including additional monitoring well installation and groundwater sampling. These data are being reviewed by the Kansas Department of Health and Environment (KDHE).
