Fred Dolislager - Senior Environmental Risk Analyst Oak Ridge National Laboratory

Fred Dolislager has worked for both the University of Tennessee and Oak Ridge National Laboratory since 1998 on the environmental restoration of the Oak Ridge Reservation. Fred began in an environmental laboratory performing TCLP and GC/MS analysis. He then transitioned into site-specific risk assessment and progressed into managing the calculation of environmental screening levels for Superfund. His exposure assessment models have also been adapted to support the assessment of residual chemical warfare agents on surfaces and the radiation risk from sources inside and outside buildings. Most of the screening levels are also provided on the internet in an interactive system that allows users to change toxicity and physical property input parameters and calculate site-specific screening levels or cleanup levels. Notable projects are: The Risk Assessment Information System (RAIS), Regional Screening Levels for Chemical Contaminants at Superfund Sites (RSLs), Vapor Intrusion Screening Level (VISL) Calculator, Preliminary Remediation Goals for Radionuclides for Superfund (PRGs), and Radon Vapor Intrusion Screening Levels (RVISLs).

The team works to identify policy issues, develop guidance and provide training regarding the vapor intrusion pathway and state’s Dry Cleaner Environmental Response Program. Jennifer also serves as the WDNR’s liaison with the Wisconsin Department of Health Services related  to vapor intrusion issues. Prior to June 2019, Jennifer served WDNR for 20 years as a Hydrogeologist in the RR Program regulating the investigation, remediation and redevelopment of contaminated properties in east-central Wisconsin, including discharges from dry cleaners, paper mills, metal plating facilities and other historical industrial and commercial operations.  She continues to serve as DNR Project Manager for a handful of these sites.
