Application of principles of physical chemistry to the description and composition of natural waters and engineering treatment of drinking water and wastewater. Studies of acid/base chemistry, complexation, precipitation, and oxidation-reduction potential chemistry.

Course Objective:  To learn how to apply the principles of solution chemistry to natural waters and engineered treatment of drinking water and wastewater.

Learning Outcomes

What you will know at the end of the course:  You will know how to solve chemical equilibrium problems and understand how inorganic chemicals speciate (behave chemically) when mixed into natural or engineered water systems.  You will learn about the chemistry of lakes, oceans, and groundwater through relevant examples.  You will learn about the chemical principles underlying many drinking water and wastewater treatment processes.  You will have the fundamental concepts to be able to apply your knowledge to other problems.


Subject to approval of the Programme Director

Assessment Due Date Percentage 
Assignments 30%
MINTEQ Project 20%
tests (x2) 50%

MINTEQ Project:  Students will be asked to use the concepts described in this report to analyse a natural water or wastewater system in New Zealand.  This could be a groundwater aquifer, a stream, a lake, or another natural water body.  It could be the drinking water supply and treatment for a municipality, the stormwater quality of the municipality, or the wastewater treatment process.  Students will need a set of water quality measurements to use as the basis of their study.  Students will use MINTEQ to analyse the water quality data, and then use course concepts to discuss and interpret the water quality data.  The written report (max. 5 pages) will be worth 10% and the oral presentation worth 10%.

Textbooks / Resources

Required Texts
