When is remediation required?
The Victorian Environment Protection Act 2017 requires owners of contaminated sites to minimise the risks of harm to human health or the environment from contaminated land or groundwater through remediation and/or management.
Contamination may need to be reported to the Environment Protection Authority (EPA) together with information related to the proposed contamination management response (Duty to Notify of Contamination (s40).
The Act sets out specific requirements to meet obligations under the General Environmental Duty (GED), the Duty to Manage (DtM) contaminated land (s39) and the Duty to Notify of Contamination (s40).
How can Landserv help?
Several factors need to be considered by Landserv’s remediation specialists when selecting an effective remediation or management solution for a contaminated site. These include the drivers for the remediation work and any constraints, risk management, technical suitability and feasibility, stakeholders’ views, cost/benefit assessment and broader environmental, social and economic impacts (e.g. sustainabllity).
Following the remediation options assessment (ROA), Landserv will design and implement the selected remediation and/or management approach.
Our remediation specialists have hands-on experience in the following contaminated remediation and management technologies:
- Excavation and off-site disposal (dig and dump)
- Monitored natural attenuation
- Soil vapour extraction
- Bioremediation (biopiles) and landfarming
- Groundwater pump and treat
- Air sparging or bio-sparging and Air stripping
- Dual-phase extraction or multiphase vacuum extraction
- In-situ chemical oxidation or fixation
- Onsite repository or onsite containment
Over the period of 2018 to 2019, Barwon Water undertook a ‘Legacy Sites Program’, involving a number of preliminary assessments across their landholdings for potential contamination. The assessments categorised various sites based on potential risk. Thirteen sites including various water reclamation and treatment plants, depots, reservoirs, and basins were identified as requiring additional on-ground intrusive [...]View Project
