Poonam Kulkarni is an environmental engineer with GSI Environmental Inc. and has over 9 years of experience in engineering and environmental consulting. She earned a B.S. in Chemical Engineering from the University of Texas, Austin, an M.C.E.E. in Environmental Engineering from Rice University, and is a Licensed Professional Engineer in the State of Texas. Poonam has extensive project experience in methods to evaluate and enhance Natural Source Zone Depletion at hydrocarbon sites, including temperature-based monitoring methods. She has served as Co-Principal Investigator on multiple DoD-sponsored research projects including those that apply innovative enhanced bioattenuation technologies at chlorinated solvent sites, evaluate and reduce variability in groundwater monitoring data, as well as a demonstration of passive soil vapor extraction technologies. Ms. Kulkarni’s professional experience also includes the design, implementation and management of remediation systems, as well as site investigation and characterization.

Internet-Based Thermal Monitoring of Natural Source Zone Depletion at LNAPL Sites

Thermal NSZD is a continuous thermal monitoring and analysis system that determines the daily and cumulative rate of LNAPL degradation in the subsurface by natural microbial activity. First, the heat generated by biodegradation is measured via a vertical series of thermocouples on “sticks” in the LNAPL zone and at least one in a background location. Next, these temperature data are transmitted automatically from the LNAPL site to a central, secure location for data storage and pre-processing on a daily basis. Finally, the data are converted to a rate of degradation using a heat balance algorithm developed by Colorado State University. Colorado State University, TRC Consultants, and GSI Environmental, in a joint venture, have developed a subscription-based internet service that allows LNAPL site owners to securely access Thermal NSZD technology and obtain continuous long-term NSZD rates from their site (patent pending, Sale et al., 2014; ThermalNSZD, 2016). With a one-time installation, the Thermal NSZD monitoring system has much lower long-term cost per location than conventional NSZD monitoring methods.
