Primary author for Remedial Action Work Plan (RAWP) and assisted in coordination for design documents and specifications. Wrote Site Management Plan following site remediation.Ms. Sandorf assisted in groundwater modeling using Visual MODFLOW. She has coordinated on model development and calibration to illustrate predictive responses to proposed remedial alternatives for site-specific model. Sensitivity analysis included effect of in-situ stabilization and solidification on DNAPL or effect of vertical anisotropy. Reduced municipal pumping data, charted chemical results to support transport model for MTBE plume in New Jersey. Created graphic animations using MODFLOW 3-D output supplement. She has coordinated on model development and calibration for former manufactured gas plant and chlorinated solvent sites in New York State, New Jersey, and Massachusetts. Developed model to simulate excavation dewatering in close proximity to waterfront. Provided Professional Geologist (PG) services for horizontal directional drill (HDD) boring in Pennsylvania.
