Where contaminants are found during Environment Site Assessment, a Remediation Action Plan for the clean-up of contaminated soil and groundwater is often required. Our consultants have extensive experience in the preparation and implementation of these plans including:
- Preparation of remediation specifications
- Supervision of contractors;
- Supervision and validation of soil and groundwater remediation projects;
- Tracking and documenting soil movements for large scale earthworks;
- Above and underground storage tank management, monitoring and removal.
Our clients range from Government departments to smaller private companies and petroleum companies across Victoria.
The Victorian Environmental Protection Agency (EPA) has rigorous guidelines pertaining to the design, installation and management of underground storage tanks, in particular those containing petroleum. These tanks can corrode, crack and develop leaks over time leading to polluted soil and groundwater.
Selected Project Experience
Major Inner Urban School Building Projects, Melbourne
Landserv has ongoing projects supervising environmental assessment and remediation for three inner urban school redevelopment projects, including excavation, offsite disposal and validation of over 8,000 tonnes of contaminated soil and more than 300 tonnes of contaminated soil containing asbestos. We supervised a licensed asbestos removalist and clearance by an occupational hygienist.
Tank Excavation and Validation – Dandenong
Landserv was engaged by an earth moving contractor to investigate the contamination conditions in soil (both in situ and ex situ) encountered in the removal of a 40 kL UST at a plastics manufacturing warehouse in Dandenong. The UST was used for the storage of Class A Phthalates, used in the manufacturing of plastic materials. The objective of the validation program was to assess the phthalate contamination status of soil sampled from the walls and floor of the excavation and from the excavated soil prior to its disposal in accordance with Victorian EPA requirements.
Targeted Soil Investigations – Insitu Classification
Landserv conducted two targeted soil investigations at service stations in Victoria. The aim of the investigations was to assess the contamination status of soils in the immediate vicinity of a proposed excavation for UST replacement works. The investigation encompassed targeted geotechnical drilling, soil sampling and classification for offsite disposal in accordance with EPA requirements and the development of a soil management plan to assist with the management of potentially contaminated soils during tank replacement works.
