This course, discusses the importance of water and air quality in terms of their ability to meet designated uses and support healthy living. Several natural and anthropogenic activities introduce contaminants and pollutants into the aquatic and atmospheric environments. These must be controlled or prevented in order to keep the water and air in good quality to meet current and further human needs. The course introduces different aspects of water/air quality management.
