ABSTRACT
This event is the first in a series of AEG talks meant to highlight Conceptual Site Models developed and applied in Triassic rift basin environments along the eastern seaboard. The Leaky Multiunit Aquifer System (LMAS, Michalski 1990) is a default conceptual groundwater flow model for contaminated bedrock sites in the Newark Basin in New Jersey. The more recently developed Discrete Fracture Network (DFN) concept can be viewed as another conceptual site model for assessing contaminant flow and transport in these fractured sedimentary rock deposits. The DFN emphasizes the importance of contaminant front and back matrix diffusion. This event will start with brief (10-15 min) presentations of each conceptualization by Ken Goldstein and Andy Michalski, followed by a moderated discussion between the two speakers on the merits of each concept, including recent revisions on the role of matrix diffusion. The participants will then join in this hopefully lively and illuminating debate relevant to contaminated groundwater at numerous bedrock sites in the Newark Basin, many of which are now in the need of re-characterization.

BIOGRAPHY
Dr. Michalski has investigated numerous contaminated bedrock sites in the Newark Basin over the last 35 years. He authored seminal papers on the hydrogeology of the Newark Basin and practical characterization methods for fractured bedrock sites. His conceptualization of bedrock as a Leaky Multiunit Aquifer System (LMAS) has become the default conceptual groundwater flow model for contaminated sites within New Jersey’s portion of the Newark Basin.  As self-employed groundwater consultant, he shares his expertise by assisting other consultants in characterization of contaminated bedrock sites.

Mr. Goldstein is a Certified Ground Water Professional and Professional Geologist with 37 years of experience in contaminant hydrogeology, groundwater hydrology, contaminated sediments, site remediation, and ecosystems restoration. Mr. Goldstein’s emphasis is in high resolution site characterization and remediation of complex fractured sedimentary rock sites contaminated with DNAPL’s. Mr. Goldstein has served as technical director or technical reviewer on more than 1000 hazardous waste remediation projects, including remediation of Contaminated Sediment sites, Chlorinated Solvent sites, Manufactured Gas Plant sites and Ecosystem Restoration-related programs. Mr. Goldstein’s academic training is in geomorphology and surface water and groundwater hydrology. He obtained his BA and MA from SUNY Binghamton. He currently is a Senior Vice President at Louis Berger US, and the operations leader for the US Water and Environmental Systems Practice. He is a member of the National Ground Water Association (NGWA), Association of Ground Water Scientists and Engineers (AGWSE), Society of Environmental Toxicology and Chemistry (SETAC), The Sustainable Remediation Forum (SURF), Association of Environmental and Engineering Geologists, Water Resources Association and the NGWA Awards Committee. He serves as an advisor to the NGWA and USEPA on characterization techniques and remediation performance metrics for fractured rock sites and is on the Steering Committee Member of the NGWA and USEPA Fractured Rock Conference.
