Due to the extensive amount and appalling degree of arsenic poisoning on the Indian subcontinent, there is a need to prevent future crises from occurring. With the advent of numerous arsenic selective sorbent media and other arsenic-removal technologies, the major environmental challenge lies not in removing dissolved arsenic from contaminated groundwater but in attaining safe, long-term disposal of arsenic-laden sludges. Safe disposal and containment of wastes would reduce the amount of toxic waste generated, prevent leaching of arsenic into soil and groundwater supplies, and allow for a more secure public. With arsenic becoming a contaminant of concern in the US due to a decreased maximum contaminant level, proper disposal and preclusion of leachability in landfills provides opportunity for profit.
Several research tasks will be performed to quantify current arsenic containment measures and to verify the capabilities of the proposed project towards arsenic disposal. Subsequent to laboratory analysis of arsenic-laden sludges and determination of ideal disposal conditions, a reactor and disposal site will be constructed in West Bengal, India. The results of the proposed research tasks will be evaluated according to standard methods for chemical analyses, such as USEPA TCLP, and will be demonstrated through decreased arsenic leaching from sludges and disposal sites.Finally the P3 concepts will be utilized as the M.S. project for the major co-investigator listed above; however, the project may also be employed as part of the Lehigh University undergraduate Capstone design project. Furthermore, certain students will be chosen from Bengal Engineering & Science University to complete work on this project.
