Law firm engagement for Preliminary and Detailed Site Investigation of Former Service Station, Inner Sydney NSW

UPSS contamination site investigationiEnvi was engaged by a law firm to complete a preliminary site investigation (PSI) and underground petroleum storage system (UPSS) investigation at a commercial property in inner Sydney to assess the level of ground contamination associated with the UPSS and the subsequent impairment on the property value. The property included a shop front and workshop of a business operating 8 am to 5 pm Monday to Friday and the investigation had to occur with minimal impact on business operations and minimal impact to the newly renovated shop front. The UPSS had been underground for almost 100 years.

iEnvi were able to undertake a thorough UPSS investigation including locating the UPSS tanks beneath the shop floor, installing groundwater wells to sample and monitor groundwater, collecting soil samples from depths of up to 3 m across the site and installing vapour pins for collection of soil vapour samples. The groundwater and samples indicated the presence of hydrocarbon contamination associated with the UPSS system and historical fill activities onsite, and some remediation would be required if the site were to sold and developed into a residential property.

This information will be used in legal proceedings to determine the value of the property, with iEnvi experts available to provide expert witness and advice.
