Water quality parameters; mass balances; kinetics; surface water quality modelling; ecological systems; treatment of water, wastewater, solid and hazardous wastes; air pollution.

Learning Outcomes

1. Describe and explain environmental quality & public health objectives and how they are informed by Māori perspectives & values.

2. Describe and explain ecology principles (i.e. nutrient cycles, species interaction) and ecosystem function & structure (i.e. population dynamics, food web); calculate energy & material flows; identify ecosystem services & discuss human influences on ecosystems.

3. Describe and estimate contaminant behaviour in the environment using mass balances, kinetics, rates of reactions, hydraulic reactor models.

4. Carry out water quality sampling, data collection and analyses, illustrating the importance of variability, reproducibility, QA/QC (quality assurance & quality control); summarize and interpret the results using appropriate units of measurement & significant figures.

5. Classify water quality (physical, chemical, biological, nutrients, heavy metals); identify water pollution sources and the impacts on the environment and public health; describe and discuss environmental risks/hazards and potential ways to minimise them.

6. Apply the concept of equivalent weights and solve environmental chemistry problems (pH, alkalinity, acid/base reactions).

7. Estimate and describe pollutant/contaminant transformation (physical, chemical biological) in environmental engineering systems i.e. drinking water & wastewater treatment, solid & hazardous waste disposal.

8. Perform laboratory-scale treatment of water samples (coagulation/flocculation) and interpret/explain/discuss the observations & results with respect to water quality objectives.

Assignment Details

You cannot pass this course unless you achieve a mark of at least 40% on the final exam. A student who narrowly fails to achieve 40% but who performs very well in the other course assessments, may be eligible for a pass in the course at the discretion of the course coordinator.

Any student who has been impaired by significant exceptional and/or unforeseeable circumstances that have prevented them from completing any major assessment items (worth ≥10%), or that have impaired their performance such that the results are not representative of their true level of mastery of the course material, may apply for special consideration through the formal university process. The applicability and academic remedy/action associated with the special consideration process is listed for each assessment item below. Please refer to the University Special Consideration Regulations and Special Consideration Policies and Procedures documents for more information.

Textbooks / Resources

Required Course Text: Partial lecture notes will be posted on Learn and can be downloaded before each lecture. There are also several copies in the library of Environmental Engineering - Fundamentals, Sustainability, Design by James R. Mihelcic and Julie Beth Zimmerman. This book is useful for ENCN281.



Students are expected to know intermediate chemistry for this course. A chemistry revision will be given at the beginning of the course to help students with weak chemistry skills (often those students who have direct entry to civil or natural resources engineering from places other than high school and/or those who have been out working for a while and have not had chemistry for many years).

Indicative Fees
