Battelle Environment Matters

Battelle Environment Matters

Eliza Kaltenberg

Eliza Kaltenberg, Research Scientist

Eliza Kaltenberg has been involved in many projects related to contaminated site assessment and monitoring of sediment remediation effectiveness, assisting with preparation of field sampling plans, data analysis and preparation of technical reports. She also has led or contributed to several client projects where passive samplers were used to assess hydrophobic contaminants in surface water, porewater or groundwater, either as a part of an ongoing site monitoring or with the purpose of designing a remedy or investigating possible sources of contamination.

Eliza also has served as principal investigator or contributor to several internal research and development projects focused on further refinements of existing passive sampling technologies, extending the suite of analytes that can be measured with passive samplers, and development of a completely new passive sampler for PFAS chemicals.

Eliza’s past research focused on understanding the interactions between sediment, water and the living organisms, also in the presence of sediment-borne contaminants. She investigated the effects of PCB contamination on the burrowing behavior of benthic invertebrates and developed new ways of two-dimensional bioturbation measurement by using non-toxic fluorescent particles. By combining colorimetry with diffusive equilibrium in thin films technology, she also proposed a new way of estimating the flux of phosphorus from sediment to the overlying water. The results of this work were published as a part of a collaborative study investigating the effects of internal loading of phosphorus on eutrophication in western Lake Erie.

Rick Wice

Rick Wice, Senior Research Scientist

Rick Wice has devoted his career to cleaning up and managing difficult contaminated sites. Now, he’s bringing his expertise to Battelle to help our clients find better solutions for sites impacted by chlorinated solvents, PFAS and other hard-to-remediate contaminants. Rick joined Battelle in September 2017 as a Senior Research Scientist. He brings more than 30 years of experience in site remediation, investigation and compliance. A geologist by training, he has developed specialized technical expertise in remediating and managing chlorinated solvents and dense non-aqueous phase liquids (DNAPL) in groundwater. He has also worked extensively with per- and polyfluoroalkyl substances (PFAS), a class of emerging contaminants found in firefighting foams as well as many consumer products. Some of Rick’s first assignments at Battelle will focus on PFAS remediation. Rick’s experience with PFAS site investigations, risk assessment, drinking water treatment and groundwater remediation will expand the team’s capacity to serve these clients. 
Kavitha Dasu, Ph.D.

Kavitha Dasu, Ph.D., Principal Research Scientist

Kavitha Dasu is working to shed light on a persistent environmental problem: per- and polyfluoroalkyl substances (PFAS). For the past several years, she has been studying the fate of organic contaminants in environmental systems and developing new analytical methods for PFAS and other emerging contaminants at the U.S. Environmental Protection Agency (EPA)’s National Risk Management Laboratory. Now, she’s bringing that expertise to Battelle to expand Battelle’s capabilities in PFAS research and analysis. Kavitha is working with Battelle’s analytical chemistry team to develop and validate methods for additional PFAS compounds. She also is working to adapt methods currently used for water and soil for other matrices, including sediments and biological tissue.
Tom Gulbransen

Tom Gulbransen

For Tom Gulbransen, better decisions start with better data. A Senior Research Scientist on the Battelle Environmental Services Team, Tom has devoted much of his 33-year career to advancing the science of ecosystem informatics. Much of Tom’s current work is focused on the National Ecological Observatory Network (NEON). Tom serves as the Project Manager for Cyber Infrastructure and Data Products Development for the program. In addition to his work on NEON, Tom supports other Battelle clients as a Senior Scientist, Lead Systems Designer or Technical/Project Manager. His recent fieldwork has focused on eutrophication and sediment contamination investigations in regional scale coastal ecosystems, such as Jamaica Bay, Great South Bay and New York Bight.  He also co-led Battelle’s work with BP on the Deepwater Horizon response, during which he helped coordinate a team of more than 100 IT staff members. He has played a key role in advancing numerous innovative software applications to serve environmental managers, such as: Multi-Criteria Decision Analysis (MCDA) models for environmental restoration, an oil spill ontology knowledgebase of over 30,000 semantic terms and relationships, a Weight of Evidence model for dredged material beneficial use planning, a fuzzy logic data evaluation tool for consensus building, an expert system for Toxicity Identification/Reduction Evaluations, and numerous database models.
Lisa Lefkovitz

Lisa Lefkovitz, Senior Research Scientist

Senior Research Scientist Lisa Lefkovitz is on the front line of sediment management for Battelle and our clients. An environmental chemist with an M.S. in Water Chemistry from the University of Wisconsin, Lisa brings more than 25 years of experience in the management of sediments and dredged materials. Over the course of her career, she has developed expertise in hydrogeology, toxicology, regulatory affairs and remediation, with a special focus on projects where sediment quality is a prominent issue.  She is especially interested in the fate and transport of contaminants in estuarine, riverine and marine aquatic environments. In her current role at Battelle, Lisa works closely with government and commercial clients to understand their goals and objectives and design solutions that will help them meet those goals. She actively coordinates field efforts, oversees the analysis of environmental samples for a variety of organic and inorganic contaminants, monitors data quality, interprets the resultant data, oversees the activities of subcontractors and prepares final reports.
