Teaching: 

Dr. Agrawal's teaching includes a sequence of two courses for an in-depth study of the sources, transformation, and the fate of contaminants in the groundwater and its remediation techniques. The first recommended course in the sequence begins in Spring semester. The students should complete 2 semesters of undergraduate chemistry coursework before they register for EES 4560/6560 (Ground Water Contamination).

Fall Semester

EES 4570/6570: Site Remediation and Management, 3 Credit Hrs (Pre-requisite: EES 4560/6560) This upper-level class investigates the physical, chemical, and biological methods used to remediate contamination in soils and groundwater.  Emphasis is on practical applications.  Strategies and technologies to address contamination, including the no-action alternative, natural attenuation, containment techniques, pump-and-treat, and in situ technologies, will be reviewed in sufficient technical detail so the student can apply the basic engineering design equations.  Included is a review of regulatory requirements and a discussion of economic constraints that play important roles in the selection of appropriate remediation strategies and treatment technologies. Learning Outcome: Through this course, the student will be able to do the following:

  • Understand the basic physical, chemical, and biological principles upon which environmental remediation technologies are based.  Understand the engineering, economic, and regulatory limitations of these technologies.
  • Understand what data are required to select from remedial action alternatives.
  • Be able to apply the knowledge of engineering principles and regulatory constraints in order to determine a remedial action strategy and select technologies to implement the strategy for a given data set at a site.

Spring Semester

EES 4560/6560: Ground Water Contamination, 3 Credit Hrs This upper-level course will provide a review of the common anthropogenic contamination distribution in the groundwater. The emphasis is on contaminant degradation mechanisms (called Natural Attenuation) by physical, chemical and microbial processes affecting their fate in soil and water (aquatic environment) that have been reported in last 2 decades.  This course provides the much-needed background for entry-level positions in environmental consulting, and also for the professional development of working geoscientists/environmental scientists. This course is a recommended elective for the Site Remediation course (offered every fall semester). Learning Outcome: Through this course, the student will be able to do the following:

  • Understand the key environmental pollutants, both natural and anthropogenic, and their sources; this includes organic (chlorinated solvents, petroleum hydrocarbons, MTBE, PPCP, and pesticides), inorganic (toxic metals, nutrients, perchlorate, radionuclides, emergent contaminants) and biological (pathogens) pollutants.
  • Understand the basic mechanisms of pollutant degradation and fate, by natural attenuation processes in the environmental systems. This will include an understanding of pollutant movement and degradation through partitioning (sorption, volatilization), dilution (dispersion), and degradation (abiotic/microbiological) of pollutants in soil and groundwater based on physical, chemical and microbiological principles.

Summer Semester

EES 4010/6010: Ground Water Monitoring and Remediation (field course), 2 Credit Hrs This upper-level field course should provide an understanding of the following topics through class lecture, site visits in the area and hands-on exercises:

  • Water quality parameters and drinking water and wastewater treatment processes; Geochemistry of groundwater/surface water; Groundwater contamination issues: petroleum hydrocarbons, chlorinated solvents, emerging contaminants; Landfills and related environmental issues; Groundwater remediation techniques of petroleum and solvents. Vapor intrusion.
Research statement: 

My research focuses on the abiotic and microbial transformations of environmental pollutants mediated by metals, minerals and microbes. They include:

  • Abiotic degradation mechanisms of organic and inorganic contaminants by: (1) granular and nanoscale zero-valent metals and catalysts, including bimetallic reductants, and (2) minerals, particularly nanoscale magnetite, iron sulfide, and iron clays. Spectroscopic characterization of the reactivity of stabilized bimetallic nanoparticles towards remediation.
  • Biogeochemical transformation and remediation of organic (halogenated hydrocarbons and pharmaceuticals) and inorganic contaminants in wetlands and similar aquatic environments by aerobic (methanotrophic and ammonia-oxidizing) microorganisms. Redox processes in shallow, vegetated aquatic environments, including role of iron and sulfur cycling in wetland soils and in plant roots towards pollutant transformation.
  • Bioenergy and biofuels. Microbiological approaches to convert greenhouse gas (CO2) into hydrocarbon fuels: role of anaerobic microbes in carbon sequestration.
