It is located in close proximity to the Choa Chu Kang housing estate. A group of five junior college students we re tasked to carry out a geography fieldwork exercise at the Sungei Kadut Indust rial Estate to investigate the impact of these industries on the environment.

Both pH and turbidity are significant measur es of water quality, whereby pH measures how alkali or ac idic the river is, while turbidity measures the concentration of particulate matter f ound in the river. Both the pH and turbidity are in turn a ffected by the nature of the effluence entering the river from the surrounding catchment area. The students chose five locations that were accessible by road for their data collection. As a group, the students moved from si te to site over the span of three hours on a Saturday morning to conduct their study. The equipment used by the students included: • White container for the water sample with Secchi disk sticker adhered to the base of the container (to measure turbidity) • 5 10ml test tubes • 10 pH test kit tablets • Indicator chart (to match turb
