Environmental Site Investigation and Groundwater Remediation at a glass manufacturing facility

Share this post

ESC conducted an Environmental Site Investigation followed by Groundwater Remediation using Pump-and-Treat technology between 2013 and 2015.

About the Project

The Client was a former 80-acre glass manufacturing facility which was seeking to divest their operations in Malaysia after operating for over 20 years. ESC first conducted an environmental due diligence study that identified possible environmental liabilities, including soil and groundwater contamination. 

The Client’s challenge was to understand the extent of soil and groundwater contamination and remediate the contamination to an acceptable level, approved by the Malaysian Department of Environment.

Our Approach

ESC conducted a series of Environmental Site Investigations which identified elevated concentrations of heavy metals, associated with historical on-site activities. Groundwater contamination was found to be at levels significantly above the Malaysian Department of Environment’s (DOE) Site Screening Levels. 

ESC conducted Phase 2 ESA, risk assessment and remediation of heavy metals contaminated groundwater at the site. Pump-and-treat technology was selected as the most appropriate approach to remove the hexavalent chromium contaminated groundwater.

ESC prepared a Remediation Action Plan (RAP), which set out the goals, strategy and approach to address the subsurface contamination at the facility. The remedial goal was to reduce contaminant concentrations to below site-specific target levels, within acceptable health risk levels.  The strategy called for the monitored treatment of the contaminants with ongoing reporting to verify contaminant reduction and post clean up validation that target levels had been met at project closure, according to a predetermined schedule and plan.


ESC was able to support the Client in all aspects of the remediation including providing technology and equipment for remediation, training for the Client’s staff to carry out the works & monitoring and serving as a liaison with the local authorities.

    ESC thinks out of the box. They can come up with conventional solutions. But they are better in providing a solution fit for the company - one that feeds your organization.

    We had no experience at first in dealing with Safety Cases and dealing with authority. When we have an issue, we ask ESC. Just one look at it, ESC already knows what to do. They  advise us accordingly and professionally and tell us what to do what to follow and to know. Our partnership with them produced good results.
