This project involves the renovation and modernization of the interdisciplinary environmental engineering and science laboratory at Manhattan College. The successful completion of this project will result in a comprehensive and unified environmental laboratory complex. Individual research and research training areas will include: unit operations/advanced water and water waste treatment; instructional/research training; aquatic and sediment chemistry research; microbiology; instrumentation; toxicology; radiological microcomputer; storage; equipment calibration/repair; glassware storage/washing. Some of the research to be supported by the renovated facility includes: risk assessment research - in a modern dedicated toxicology lab overseen by a new faculty member; the continuation and expansion of breakthrough research to determine toxic effects based upon acid volatile sulfide contents of sediments - in a dedicated acquatic and sediment chemistry lab; investigation of new techniques for advanced treatment of water and wastes such as biological fluidized beds and odor control - in a renovated unit operations lab; and enhancement of research characterizing risk to the ecosystem and human health of genetically engineered microorganisms - in a dedicated microbiology lab. Additionally, hundreds of thousands of dollars of research instrumentation acquired under various sponsored projects will be housed in a climate controlled instrumentation lab.
