A course in which students apply principles of environmental chemistry, chemical analysis, Geographic Information System software (GIS), Geoinformatics, computer-assisted problem solving, teamwork and communication skills. The course will be multidisciplinary in nature. This course involves field work with a lab component, which will facilitate an understanding of the water chemistry, the effects of environmental, human and engineered factors, and an understanding of the fate and transport of contaminants in the water. Measurement of pH, temperature, dissolved oxygen (DO), total dissolved solids (TDS) will be taken during a canoe trip in a section of the Carmans River on Long Island . Samples will be analyzed in the laboratory for Total Dissolved Carbonates (CO2) and Nitrates. Developing an understanding of chemistry in the river environment is an essential component of the course. Students will learn to use instruments designed for the collection and analysis of chemical data. GIS technology will be used to map the river. Students will learn to use GPS to acquire data in the field and enter the data to prepare maps through GIS. Interpretation of the changes in river chemistry due to the above mentioned factors over the length of the river traversed will be plotted on the map. Use and interpretation of aerial photographs will be briefly touched upon.
