Students will attend a series of lectures that will present the basic scientific principles related to hydrology and water quality, particularly as related to Onsite Sewage Facilities (OSSFs). Hydrology topics will include the movement of water through the soil by infiltration, percolation, and through overland flow processes. Water quality topics will include the physicochemical properties, transformations, and pathways of nitrogen, phosphorus, and bacteria. Additionally, students will gain a working knowledge of the functional operation of anaerobic and aerobic OSSFs and wastewater reuse systems. Students will use this knowledge to conduct research to address a variety of challenges related to use of OSSFs, and learn about transport of nitrogen, phosphorus, and bacteria through soil and water system.
