Site Contamination Services

Preliminary Site Investigation (PSI)

Involves the desktop study and review of information from government portal, aerial imagery, historic activities on site from land ownership, that could lead to any potential contamination. If you are buying a property, and you are concerned about any environmental risk from previous activities – we recommend you to start at this process and minimise your risk from unknown contamination sources.

Remedial Action Plan (RAP)

If contamination is identified in Phase II investigation, a Remediation Action Plan is developed. This plan will propose the possible remediation strategies, to manage contamination, based on the land use and development.

Acid Sulfate Soil Services

If unnoticed, acid sulfate soils are usually dormant and does not indicate the contamination (typical colouration of soils from iron deposits) until excavation has occurred, but it is too late by then. If soils are determined to be Acid Sulfate Soils (ASS), then suitable treatment strategy is developed in the form of Acid Sulfate Soils Management Plan.

Environmental Approvals

Our Consultants are qualified Scientists and Engineers with over 10 years of experience in specialised fields and understand the relevant regulations and provide practical solutions.

Detailed Site Investigation (DSI)

A DSI or a stage 2 investigation involves a detailed investigation of the soils on site for potential contamination. The DSI will provide a better understanding of the contamination status of the site along with a detailed conceptual site model and may involve groundwater and surface water investigation. We have a team of contaminated land consultants who can deliver DSI reports as per Council and EPA requirements.

Validation Assessment (VAL)

Validation sampling programme is undertaken to ensure that the soils were remediated to meet the required health and environmental standards. If soil quality meets the relevant standards, the investigation can be considered completed. Where complete clean up is not feasible containment and ongoing monitoring will be required post-validation.

Water and Groundwater Assessment

During groundwater investigations, Hydrogeological experts at K2 Consulting Group undertake thorough assessments using hydrogeological (groundwater) modelling tools to ascertain flow direction, and the extent and level of contamination plume within the aquifer.

Environmental Reports for DA and Councils

We have extensive knowledge on Council DA requirements for development projects, including sub-division, brownfield, and change of land use. Our expert team can assist you with Council and EPA notices in relation to soil contamination.
