Water Quality Monitoring in Singapore
Authored by Kwok Chen Ko, in collaboration with PUB – Singapore’s national water agency, "Your First Guide to Water Quality Monitoring in Singapore" allows teachers and students to explore water quality monitoring with minimum academic theory. The key topics covered include:
- The most critical water quality parameters to monitor.
- How to design a robust water quality monitoring programme for a chosen water body.
- Common problems encountered and how to avoid them.

i saw the feedback on talking point displaying that filtered water has bacteria in it, but since SG water is chlorinated throughout the system at a min quantity, i wish to know how the bacteria grow is possible with chlorinated water flowing throughout.
I am not involved in that study which was conducted by CNA so I do not know the details of the water filtration systems and how they were operated.
I surmise that the filter system could have removed the chlorine (perhaps by activated carbon), thus allowing bacteria to grow in the dechlorinated water.
