Thanks to our teacher, Mr Tan, we were able to start this project. He accompanied us when we went to the actual test site to ensure our safety. He demonstrated to us how to collect the water easily. Despite how hot the weather is, he will accompany us to ensure our safety when collecting the water.

We would like to give special thanks to Ms Su and Ms Tan for helping us when we needed to use or acquire equipment from the laboratory. They helped us to save time when we were not sure on operating the equipment as they provided demonstrations instead of us doing trial and error. They prepared the equipment for us ahead of time, including calibrating the equipments, storing the large bottles of water for weeks. They also helped us to ensure that our experimentation was not flawed, ensuring that our results are not interfered too much by factors such as bacteria (sterilisation of bottles).
