Timetable Note

There will be weekly on-line tutorials, starting in Week 3.  The tentative date/time for these is Mondays, 17-18, and so the first tutorial will be on Monday, 4 March.  These will be held through Learn using Zoom and all students must be enrolled to reach the tutorial.  A small part of the course marks are based on tutorial participation.

Weekly tutorials 5%

1. Assignments 30 %
2a. Group laboratory report 5 %
2b. MINTEQ report 5 %
3. Weekly tutorials 5 %
4. Test 25 %
5. Examination 30 %

1. Assignments: completed individually and submitted on Learn.  One assignment will be submitted during the block.  The first assignment will be due on Wed. 6 March.

2. Short reports
2a. Laboratory report:  How to limit iron in groundwater wells?  Explore amount of oxidant needed for treatment.  Apply reduction-oxidation concepts.  Use MINTEQ to check against laboratory results.
2b. MINTEQ:  Go through a series of MINTEQ exercises and answer short questions.  

3. Weekly tutorials:  A total of 5% is available for attendance and readiness to participate in the weekly tutorials.

4. & 5. Test and Examination: Three hours each; to be held using Learn and Zoom for monitoring.

In the case of an emergency that affects the whole course, the Course Coordinator, in consultation with the Dean, may change the nature, weighting and timing of assessments, e.g. tests and examination may be replaced with assignments of the same weight or different weight at a different time and/or date (which, under certain circumstances, may be outside the prescribed course dates).  The ‘Special consideration’ process will also be used for unforeseen circumstances that adversely affect the academic performance of students individually. The usual grounds for this are described in the UC policy ‘Special Consideration Procedures and Guidelines’, and personal circumstances due to a wider emergency event may also qualify.

Textbooks / Resources

Required Texts

Snoeyink and Jenkins; Water chemistry ; Wiley, 1980.

Water Chemistry, by Snoeyink and Jenkins, John Wiley, 1980. All students are expected to obtain access to the book and read the assigned sections. I have a limited number of copies I can provide to students. In addition to personal and library copies, copies can be purchased used through abebooks.com, bookfinder.com or other used booksellers.


Who is this course designed for:

1. Students studying in non-water MCivEng endorsements wanting a course to add breadth to their studies (eg, students studying concrete or environmental effects of architectural choices)
2. Students planning to take courses that require this course as a pre-requisite
3. Students studying for the Water Eng. endorsement who will receive fundamental knowledge applicable to a wide variety of water problems.

Teaching Mode: The course is very dependent on students reading and learning from a textbook. The course is taught by distance with assistance on assignments. There will be a series of on-line lecture modules for students to download to assist their study. Students will submit assignments via Learn for marking. Learn will also be used for discussion regarding assignments or questions on course content. In addition, there will be two intensive blocks. Students will learn new concepts and at the same time understand how to analyse these concepts using the computer software package, MINTEQ.
