Environmental Site Assessment and Groundwater Remediation

We provide turn-key environmental site assessment and groundwater remediation planning, design and application services

SUPRA provides a wide range of services related to soil and groundwater quality and quantity including environmental study, pollution evaluation and remediation design. Our environmental specialist and groundwater engineers study, assest and develop a comprehensive evaluation and prediction of contaminant migration, environmental impacts and water supply analysis. Our services ranging from environmental impact evaluations for groundwater and surface water resources to groundwater and surface water contamination studies. We provide a full range of groundwater and environmental remediation, investigation, environmental drilling services, study and consultancy, and key technologies to meet our client expectation. 

We are able to conduct phase I, II, III environmental site assessment (ESA) to identify potential or existing environmental contamination liabilities. The assessment shall includes examination of potential soil contamination, groundwater quality and surface water quality. The examination of the site may include: definition of any chemical residues within structures; identification of possible contamination materials and inventory of hazardous substances stored or used on site. With expertise from environmental specialist and groundwater engineers to PhDs, we partner with you to deliver the right approach of environmental site assessment and groundwater remediation for the most complex cases given.

SUPRA provides Phase I, II and III environmental site assessments

At Phase I ESA, we conduct comprehensive observation of the current and past conditions and uses of the property and adjacent properties; reviewing local regulatory databases including, but not limited to, underground storage tanks (USTs), aboveground storage tanks (ASTs), known or suspected release cases, the storage of hazardous substances and disposal of hazardous wastes including petroleum products, and institutional and engineering controls; and reviewing historical records, such as historical aerial photographs, fire insurance maps (Sanborn maps), historical city directories, and historical topographic maps. The data are the compiled to set up the SPR (source-pathway-receptor) chart of potential contamination.

Phase II ESA is an intrusive investigation to identify and determine the nature and extent of potential contamination. This normally follows a Phase I ESA where actual or a potential for contamination was concluded. This assessment involves reviewing data result from laboratory to local and international regulations, reviewing geological data and verified the potential contamination and the way its migrated (apparent contamination exists at high-enough levels or above regulatory limits). These types of investigations involve drilling of boreholes and/or opening of test pits to collect soil and water samples at specific select locations of concern. Monitoring well are constructed to evaluate and monitor the groundwater at the site. The subsurface conditions logged at the site include soil stratigraphy, groundwater flow, direction and gradient. Groundwater Monitoring Event (GME), routine groundwater field testing, sampling and reporting, and continuous maintenance of monitoring wells are done and the data acquired will be compiled as comprehensive groundwater summary report with conclusions and recommendations.

Phase III ESA is aimed to to further identify the extent of environmental contaminants found during the Phase II Environmental Site Assessment process. It includes determining the amount of soil and groundwater impacted by environmental contaminants, completing a Site Notification Report to notify regulatory bodies of site contamination, developing a Remedial Action Plan (RAP) to remove environmental contaminants from the property and assessing options available for parties involved, including costs and timelines of remediation. We are developing an environmental remediation strategy and work plan
