Ms. Pearsall is a founding member of CPF Associates, Inc. She is an environmental scientist with over 20 years experience in environmental and analytical chemistry, exposure and risk assessment, and hazardous waste site investigation and remediation. Previously, she was a Managing Consultant at The Weinberg Group, a Project Manager at the Clement Division of ICF/Kaiser, a Senior Scientist at Martin Marietta Environmental Systems, and a Staff Scientist at Environ Corporation. Ms. Pearsall assists clients in developing risk-based remediation strategies that minimize liabilities under RCRA, CERCLA/SARA, TSCA, OSHA and at property transfer and acquisition sites. Her specialty is in the development of innovative approaches and creative solutions for approaching waste site problems, bringing to bear her extensive knowledge of cost recovery pitfalls in addressing these issues. Ms. Pearsall has worked under traditional Superfund programs, the Superfund Accelerated Cleanup Model (SACM), state hazardous site programs, and RCRA corrective action. She is an experienced negotiator with USEPA and state regulatory authorities on issues surrounding remedy selection and cost-effectiveness, exposure, risk, cleanup goals, divisibility of liability, cost allocation, and remedial strategies. During her career, she has performed hundreds of risk analyses for hazardous waste site projects on behalf of public or private sector clients. Her training in environmental and analytical chemistry has benefited her clients in matters pertaining to chemical fate and transport evaluations, source apportionment, testing strategies for the environmental behavior of new products, data validation and review, analytical laboratory problems, statistical interpretation of data, and the development of new analytical methods. Because of her practical experience and technical training, Ms. Pearsall is often retained to provide expert review of the quality of risk assessments, sampling plans, compliance programs, remedial designs, the need for remediation, and reasonableness of remediation costs. She also has served as a guest lecturer at Johns Hopkins University and has developed and conducted numerous risk assessment training courses.
