SRS prepared a sampling and analysis plan and conducted subsurface soil sampling to characterize and evaluate PCE and TCE contamination. SRS used Multi RAE VOC/ CO/O2/combustible gas/H2S air monitoring equipment during sampling activities to support selection of the proper level of PPE and to protect samplers from contaminant exposure. SRS completed and submitted a draft Removal Assessment Report that included evaluation of contamination, exposure pathways, and the applicability of NCP criteria with respect to a potential removal action.
