3-D Contaminant Transport Modeling using Visual MODFLOW Pro

Groundwater flow and contaminant transport modeling was performed using Visual MODFLOW Pro on a Landfill in Kuala Lumpur (Malaysia). The study has successfully delineate the contaminant migration pathway and 3-D models were developed to visualize these contaminant pathways.
(i) 2-D Model of contaminant transport(ii) 3-D model of contaminant transport after 2050 days (about 5.7 years)

(iii) 3-D model of contaminant transport after 7200 days (20 years)

Congratulation to Dr Fares As Shaebi - my PhD student

Congratulation to Dr Fares As Shaebi who has been awarded a doctor of philosophy (PhD) in Environmental Geology during a Convocation Ceremony in UKM very recently. Dr Fares is my PhD student and he has successfully conducted a research with a topic "The Potential Use of Natural Geologic Materials for Remediation of Contaminated Sites". He also has published his results in Journals and local/international conferences. I wish him all the best .

Water Level Sensor for Putrajaya Wetland Monitoring Work

Perbadanan Putrajaya has successfully installed water level sensors at eleven (11) monitoring stations around Putrajaya Lake and Wetlands. The instrument can automatically measure water level every 10-minutes and the data can be retrieved from the data logger using a portable PC. Photos show the water level sensor instrument and a field demostration of using this equipment by Global Water to all people involved with the monitoring project namely Alam Bersih Sdn. Bhd, Engineers from Perbadanan Putrajaya and the consultants.

Site visit to Taman Beringin closed landfill in Jinjang, Kuala Lumpur

Half-day site visit to Taman Beringin former landfill (which was already properly closed) was conducted with a team from IKRAM Bhd. The visit was part of the consultation work to identify the leachate outflow from this former landfill to surrounding water bodies adjacent to this area, namely Sungai Batu and several man-made ponds. The study will be conducted using a MODFLOW groundwater simulation software to look at this problem and to recommend the best remediation option available to hinder the flow of leachate into water bodies. Photos show the condition of the site during the site visit.

Nano Zero Valent Iron (NZVI) produced at the Geochemical Laboratory, Universiti Kebangsaan Malaysia

A new advanced material for groundwater treatment was successfully developed at Geology Laboratory in UKM. This material was developed by my MSc student (Ms. Noraznida Kamaruzaman) using chemical reducing method in the laboratory. This research was funded by FRGS Research Grant from MOSTI. Below are some photos of the NZVI. Further research is still in progress to characterize the material and to determine its adsorption capacity.
