SELECT PROJECT EXPERIENCE
Remedial Investigation/Remedial Action Investigation — N}
Provided data review and usability technical oversight on the investigation, assessment, and
remediation of soil and aqueous matrices contaminated with hexavalent chromium. Responsible
for providing oversight of two analytical laboratories and for coordination of data review, DV, and
data usability for all parameters based on the NJDEP and EPA Region 2 DV Standard Operating
Procedures (SOPs) and/or the NJDEP Data of Known Quality Data Quality Assessment (DQA)/Data
Usability Evaluation (DUE) protocols. Communicated frequently with the laboratories to ensure
proper receipt of samples, proper utilization of project-specific analytical protocols in order to
achieve necessary project action levels, and to monitor the overall performance of the
laboratories.
Remedial Investigation — IN
Assisted in the preparation of the QAPP and updated as applicable for multiple phases of the
program. Aliso responsible for providing QA support to the field team and coordinated with
laborataries to ensure achievement of risk-based standards. Ms. Krowitz either performed or
provided oversight of data validation of aqueous, soil, and solid samples for metals and
radiological isotopes.
