IEP 281: Water and Air Pollution Chemistry examines the applied chemistry of water and air pollution. Major topics include: physical and chemical characteristics of water and air, water and air pollution, quantifying water and air pollution, water and air sampling, water treatment, wastewater treatment, mass balance modelling and air pollution dispersion. Applied concepts cover chronic and acute toxicity testing, use of colorimetry and AAS to identify and quantify pollutants, variable speed pumps used with pollution trapping devices for air sampling, gas detection tubes and air sampling meters. Use of spreadsheets for data analysis is an essential component of this course.
Prerequisites: TWC 151 Introduction to Technical Communications II, MATH 291 Resource Statistics II, IEP 266 Applied Microbiology and IEP 280 Environmental Chemistry.
Note: Pre-requisite(s) can be waived with the permission of the Instructor.

Learning Outcomes
Upon successful completion of this course, the learner will be able to:
- Discuss and classify water and air pollution and related concepts such as criteria pollutants, pollutant sources, point and non-point sources, effects of pollutants, pollution control technologies.
- Critique broad paradigms to manage water and air pollutants such as critical loads, supply or demand management, dilution versus elimination of pollutants at their source, and specific strategies such as wastewater treatment and air pollution control.
- Perform a quantitative chronic toxicity test, interpret the results, and assess the amount of pesticide residue in a soil sample using geometric dilution, treatment replication, statistical analysis, and data presentation using Excel.
- Operate and compare a light spectrophotometer with an atomic absorption spectrophotometer for quantitative analysis of various metals in water samples and present the results using a spreadsheet.
- Survey and evaluate drinking water and wastewater treatment processes to provide the appropriate level of treatment in different contexts.
- Apply mass balance modeling to solve steady state pollutant concentration problems, and compare the use of a stack emission computer model with calculating the ventilation coefficient to predict downwind dispersion and maximum point of impingement air pollutant modeling.
- Calibrate and use a barometer, a variable speed pump, and an impingement tube to measure quantitatively a specific gas and report the results in equivalent formats.
