I'm having trouble finding information on this dot point:
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 puriy water
-chemical additives in the water and the reasons for the presence of these additives
Thanx
