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 investigations.

This project involved a wide variety of contamination assessment disciplines depending on the legacy of each individual site. Works included targeted soil contamination investigations throughout current and former operations depots. Investigation and delineation of areas known to have been subject to historical landfilling activities. Classification of soil stockpiles of unknown origin for potential reuse and/or off-site disposal purposes.

Landserv successfully coordinated the complex program of works to simultaneously assess all thirteen sites over approximately a 2-3 month period. All safety preparations, plant hire, licencing, traffic management, permitting was taken care-of. Regular communication from the project team with client representatives, site operators and management staff, ensured all project objectives and deadlines were achieved.


  • The intrusive investigation provided tangible assessment of contamination risks
  • Cost savings in project management through a large-scale coordinated program
  • High-quality reporting coupled with real, manageable outcomes
  • Potentially contaminated soil materials were reclassified for beneficial reuse purposes
