Preliminary Site investigations (PSIs) generally involve a desktop investigation, including a review of historical and current land uses and activities as well as EPA public registers to assess the potential for land contamination to be present.
A Detailed Site Investigation (DSI) involves intrusive works to investigate the nature and extent of contamination and potential risk to human health and the environment.
Soil contamination can arise when:
Typical contaminants that can contribute to soil contamination include:
Surface water contamination can occur through surface runoff, discharge directly into a waterway or from an up-gradient source of contamination.
Groundwater quality assessments are necessary to determine the extent of contamination and the risk to environmental and human health. Helia EHS can manage groundwater assessments from the planning to implementation and review phase including:
Helia EHS has completed many groundwater investigations and remediation programs to help achieve Clean-Up So Far As Reasonably Practicable (CUSFARP) as part of environmental audits.
Where soil and/or groundwater has been noted to contain volatile contaminants (e.g. fuels, solvents, etc.) soil vapour may be present and a potential risk may exist to site users or visitors. Depending on the type of contaminant, soil vapours can cause serious acute and chronic health effects if not appropriately managed.
