Environmental Baseline Study

An Environmental Baseline Study (EBS) is a soil and groundwater investigation carried out to:

  • Establish the baseline level of potential contaminants in the soil and groundwater beneath the site
  • Assess the extent of contamination of the site

Decontamination works for the site will be dependent on the EBS results.

If your business involves pollutive activities or stores diesel, petroleum or flammable materials, an EBS is required when you:

*Includes En-bloc Redevelopment (EBR) cases or cases where JTC buys back your leases.

^Includes transfer cases such as corporate restructuring.

An EBS can take up to 4 months to complete.
