(./)\\r\\n\\r\\nRepresentative Projects\\r\\n to Present: Arsenic treatment using constructed wetland (Toledo, OH) [USDA funded]\\r\\nA HYDRUS D based design framework and water budget was estimated for a constructed wetland. Key microbial and physicochemical parameters which affect the arsenic retention were envisaged. Experimental design for microbial, adsorption study and sequential extraction were done. VisMINTEQ based geochemical modeling was conducted to understand the role of physicochemical parameters on arsenic retention and speciation.\\r\\n\\r\\n – : Process Based Life Cycle Assessment Tool Development (Toledo, OH) [USEPA funded]\\r\\nFor road construction materials an Excel based comparison tool was developed taking life cycle assessment approach. The tool developed from the project is named as ‘BenReMoD’ and available online for use. The objective of developing the tool is to compare various materials taking into consideration of global warming, acidification, and various toxicity categories.\\r\\n\\r\\n – : Interaction of Soil Organic matter and Organochloro Pesticide- Endosulfan (Vancouver, Canada) [NERC, Canada funded]\\r\\n Main objective of the project was to found the preferential carrier of endosulfan from agricultural field. It was hypothesized that soil organic matters is the probable main carrier of endosulfan. Three compounds (i) alpha endosulfan (ii) beta endosulfan and (iii) endosulfan sulfate were taken for the study. For soil organic matters, soil humic acid and soil fulvic acid, manufactured by International Humic Substance Society, was used. For interaction study, two kinds of experiments (i) solubility enhancement method and (ii) Dialysis bag technique were conducted. \\r\\n\\r\\n – : Modeling of Flow through a Upflow Sludge Blanket Reactor (UASBR) [Roorkee, India]\\r\\nTasks include in this project were literature review, performance data collection for UASBR treating various types of waste. A model was developed to simulate the performance data correctly. Later multivariate analysis was conducted for finding key parameters which affect the performance of the reactor.\\r\\nStudent Advising\\r\\n• Chirjiv Anand (M.S.
