Pre-purchase or due diligence assessment is essential to better understand the viability of a development by identifying potential contamination or other constraints that may influence the site suitability for development. Environmental constraints may include contamination of soil or groundwater, presence of hazardous materials such asbestos, Acid Sulfate Soils/Salinity, underground fuel storage tanks, presence of rock, or shallow groundwater.

Our assessment can include desktop review of site history and land historic land use to determine onsite investigation to identify potential constraints or environmental liabilities.

Saline soils and acid sulfate soils can affect human and environmental health and also impact durability of construction components.

St. Quentin Consulting can complete salinity assessment and acid sulfate assessment in Coastal Acid Sulfate (CASS) areas and Salinity Management Overlay (SMO) areas to confirm risk through detailed study and appropriate laboratory testing.

Unused underground petroleum tanks/systems present a potential risk to human health and the environment. Where an underground tank has not been used for 2 years, it must be decommissoned in accordance with Australian Standard AS4976-2008, ”The removal and disposal of underground petroleum storage tanks”.

We have expertise in locating, testing and delineating potential contamination in and around an existing underground tank. We can provide specific advice and methodology in removing and remediating the tank location and surrounding site.

Land Capability Assessment (LCA) is essential to assess effluent treatment and disposal in non-sewered areas. Our staff have over 25 years’ experience in LCA investigation, having completed assessment for single land parcels, sub-division, commercial development, land scale residential development and expert witness services for re-zoning. We can provide an LCA assessment for individual and proposed sub-division sites.

An appropriate LCA is critical to ensure effluent is appropriately treated and contained on site. As the leading experts in the region, we have a thorough understanding of the legislative and technical requirements.

We have specific expertise in providing wastewater solutions for highly constrained sites, including steep landslide prone areas, small sites and commercial developments.
