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[/cs_text][/cs_column][/cs_row][/cs_section][cs_section parallax=”false” separator_top_type=”none” separator_top_height=”50px” separator_top_angle_point=”50″ separator_bottom_type=”none” separator_bottom_height=”50px” separator_bottom_angle_point=”50″ style=”margin: 0px;padding: 45px 0px;”][cs_row inner_container=”true” marginless_columns=”false” style=”margin: 0px auto;padding: 0px;”][cs_column fade=”false” fade_animation=”in” fade_animation_offset=”45px” fade_duration=”750″ type=”1/2″ style=”padding: 0px;”][cs_text]
Students learn to:

• identify that water quality can be determined by considering:
  • concentrations of common ions<//li>
  • 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
• 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

• 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:
  • identify heavy metal pollution of water
  • monitor possible eutrophication of waterways
• 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
