Module 3 | Chemical monitoring and management

Focus 5: 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.

Lesson 1 | Water quality

  • Identify that water quality can be determined by considering:
    – concentrations of common ions
    – total dissolved solids
    – hardness
    – turbidity
    – acidity
    – dissolved oxygen and biochemical oxygen demand

  • Identify factors that affect the concentrations of a range of ions in solution in natural bodies of water such as rivers and oceans

Lesson 2 | Water tests

  • Perform first-hand investigations to use qualitative and quantitative tests to analyse and compare the quality of water samples

  • Identify that water quality can be determined by considering:
    – concentrations of common ions
    – total dissolved solids
    – hardness
    – turbidity
    – acidity
    – dissolved oxygen and biochemical oxygen demand

Lesson 3 | Tests for heavy metals and eutrophication

  • Gather, process and present information on the range and chemistry of the tests used to:
    – identify heavy metal pollution of water
    – monitor possible eutrophication of waterways

Lesson 4 | Features of town water supply

  • 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

  • Describe and assess the effectiveness of methods used to purify and sanitise mass water supplies

Lesson 5 | Microscopic membrane filters

  • Describe the design and composition of microscopic membrane filters and explain how they purify contaminated water
