How can we help you with Environmental Assessments in Sydney?

We undertake Preliminary Site Investigations and/or Detailed Site Investigations to assess the soils on-site based on various codes and guidelines as per the National Environment Protection (Assessment of Site Contamination) Measure (NEPM 1999, revised 2003).

If any contamination is identified in the soils onsite and requires remediation, a remediation plan report is prepared, and a remediation contractor is engaged. Upon completion of the clean-up (post-remediation), further testing of soils is undertaken, and a validation report is prepared, which would then deem the soils on site are clear of contamination and that the site can be used for the proposed development or existing use.
