RBCA Tool Kit for Chemical Releases

I have purchased a new software called RBCA Tool Kit for Chemical Releaases v2.6 from GSI International Inc (  The software was designed by GSI  to meet the requirements of the ASTM Standard Guide for Risk-Based Corrective Action (E-2081).  This software provides expanded flexibility and additional risk and transport models to allow for even easier application of this essential software tool to develop risk-based soil and groundwater clean-up levels consistent with local regulations or requirements around the world.

Thanks to all visitors who have visited my GERG Blog.  Below is the statistics of the page views according to countries.  Thank you for your support!.

Testing mobile blog update on my Samsung Android phone.

YES, It works!!. This is a blog update using my Samsung Android phone. 

Environmental Site Assessment (ESA) - Phase II

Environmental Site Assessment (Phase II) has been conducted to determine the risk of oil contaminated site to human health and the environment.  Detail and intrusive investigations involved drilling, constructing monitoring wells, sampling of environmetal media impacted and conducting a Tier 1 risk assessment.

Groundwater Modeling of Krubung Landfill Site in Melaka

Groundwater flow and contaminant transport modeling has been conducted very recently at Kerubung Landfill site in Melaka.  The simulation of groundwater flow and transport was conducted using Visual Modflow Pro software.  The model was simulated at 5, 10 and 20 years after the released of leachate from this landfill.

Virtual Fieldwork for Geologist

This project is about a virtual fieldwork.  The main objective of the project is to develop a new virtual fieldwork software for geology student in Universiti Kebangsaan Malaysia. This project is funded by Universiti Kebangsaan Malaysia under its "Pelan Tindakan Strategik" research grant.  The project will be conducted with my new MSc Student, Abang Casfian.

Groundwater Modelling on a slope failure at Jalan Puteri 9/2, Bandar Puteri Puchong

The site is located at Bandar Puteri 9, Puchong in Selangor.  The site is surrounded by a hilly terrain on the east and south of the area.  There is also a small stream located on the north side of the site, flowing east-west.  The site was excavated for a housing development and was levelled by cut and fill method.  The south part (hill) was cut and the cut material was used to fill up the valley up to a platform level.  During the filling process, the natural drainage pattern was also filled, resulting blockage of the existing river and later may influence the groundwater flow pattern in this area.

One day trip to City of Pompeii, Naples, Italy

Finally, my ambition to visit and explore the City of Pompeii was achieved.  It was a day trip to City of Naples and Pompeii from Rome using Green-Line Tour Bus.  It was so exciting, I learnt a lot  during the visit especially about the tragedy of Pompeii .  Hopefully my visit will be beneficial for my Environmental Geology class where the ruined of Pompeii is part of my lecture.

My New Internship Student, Mr Shohta Kihara

Mr Shohta Kihara, a graduate student from Kyoto University in Japan will be working in my Laboratory for three months starting from 4th of September 2012.  He will be conducting a research on the migration of heavy metals through natural granitic soil.  He will conduct three major experiments in his laboratory work such as batch sorption test, leaching column 1g and miniature column centrifuge testing. He will also work closely with me to experience the waste disposal by landfilling and contaminated land management in Malaysia.

Radionuclide Impact Assessment (RIA) in Bintulu Sarawak

I've been appointed as Geology and Hydrogeology consultant to Asialab (Malaysia) Sdn Bhd to conduct a geology and hydrogeological study of a proposed smelting plant in Bintulu Sawarak.  The study involved groundwater modeling using MODFLOW computer software, description of the geology and seismic acitvity of the project site.   The study was part of the Radionuclide Impact Assessment (RIA) study that is required by Malaysia Department of Environment.

GROUNDWATER - What, Why, Where & How?

Attending Groundwater Conference - What, Why, Where and How?.  The conference is held at the Ruby Ballroom, One World Hotel in Petaling Jaya.

Climate change brings about a lot of uncertainty and it may affect the water supply. The water from some rivers is just too polluted so we are studying if groundwater can be exploited,” (Natural Resources and Environment Minister Datuk Seri Douglas Uggah Embas)

Groundwater Sampling at Tanjung Duabelas in Banting Selangor

Sampling for groundwater samples was conducted together with Mr Jasni Yaacob (LESTARI), Mr Atea Al Porakes (my PhD student) and Mr Farid Adnan (Geochemistry technician).  The sampling was conducted via several boreholes that were drilled using hand auger for up-to 10 m depth.  The water levels in the boreholes were firstly measured using dip meter and then purging was performed using a pump to remove all stagnant water inside the wells.  Sample was collected after a few hours using a bailer - Dr Wan Zuhairi Yaacob

Environmental Site Assessment (ESA) at abandoned Tin Mine of Sg Lembing Pahang

A fieldwork was conducted at Sg. Lembing ex-mining land on Saturday July 7th, 2012.  It was part of the requirement for Geo-Environmental coursework STAG3342 (Geo-environment & Anthropogenic Influence). The main objective of this fieldwork was to give exposure to students how to conduct site investigation of contaminated land according to Contaminated Land Management and Control Guidelines: Assessing and Reporting Contaminated Sites, that was introduced by Department of Environment Malaysia in 2009. 

During the fieldwork, students were divided into two groups. They were requested to do soil, surface water and groundwater samplings and also produce a simple Conceptual Site Model (CSM) of the site and taking into account the relationship between source -- pathways -- receptors.  Report will be submitted at the end of the semester (before the final exam week). -- (Dr Wan Zuhairi Yaacob)
