Monitoring and Management >
Human activity also impacts on waterways. Chemical monitoring and management assists in providing safe water for human use and to protect the habitats of other organisms
Students learn to:
- identify that water quality can be determined by considering:
- identify factors that affect the concentrations of a range of ions in solution in natural bodies of water such as rivers and oceans
- describe and assess the effectiveness of methods used to purify and sanitise mass water supplies
- describe the design and composition of microscopic membrane filters and explain how they purify contaminated water
Students:
- perform first-hand investigations to use qualitative and quantitative tests to analyse and compare the quality of water samples
- gather, process and present information on the range and chemistry of the tests used to:
- gather, process and present information on the features of the local town water supply in terms of:
- catchment area
- possible sources of contamination in this catchment
- chemical tests available to determine levels and types of contaminants
- physical and chemical processes used to purify water
- chemical additives in the water and the reasons for the presence of these additives
