Water Science
Overview
The aim of this unit is to discover and apply the scientific knowledge required to identify likely water-based pollutants, their effects, how to detect and quantify them and how to treat them. Students will apply this skill set across a variety of water bodies including drinking water, wastewater and recreational water.

Learning outcomes
Students who successfully complete this unit will be able to:
- Describe the environmental impact of industrial and domestic pollution on water quality
- Formulate relevant treatments to remediate water contaminated with a variety of pollutants
- Use a Hach kit and lab techniques to analyse selected chemical contaminants in water
- Describe some of the issues involved in swimming pool water quality and create solutions for these problems
- Assess water management and the capacity for water as an alternative energy source

Hurdle
As the minimum requirements of assessment to pass a unit and meet all ULOs to a minimum standard, an undergraduate student must have achieved:
(i) Â Â An aggregate mark of 50% or more, and(ii) Â At least 40% in the final test, and(iii) Completion of a specific fraction of non-reportable laboratory work based on the criteria for successful completion as explained in the lab handout(s).Students who do not successfully achieve hurdle requirements (ii) and (iii) will receive a maximum of 45% as the total mark for the unit.
