A presentation by Avas Export Import Malaysia Sdn Bhd was held at JKP16 operation centre on 23rd October 2010. It was conducted to understand more about using Clinoptilolite (a type of Zeolite) to treat the Wawasan lake's water and underground stream coming from the slope. It was found that the underground stream contains natural minerals hence causing a metallic layer on top of the lake. The metallic layer prevents sunlight from shining into the lake-bed which make it not conducive for plankton growth.
The session was attended MPSJ officers, councilor Tan Jo Han, JKP 16 and Resident Associations. A further study will be conducted by MPSJ to evaluate the viability of using Clinoptilolite to treat the lake's water.
