Ecotoxicology Division - Capabilities...


In conjunction with GEOTECH's extensive laboratory services we are able to offer a one-stop consulting service for ecotoxicology testing and chemical analysis. GEOTECH staff confer with the client to provide accurate advice which aids in solving their environmental problems. GEOTECH staff are highly skilled in environmental project development, project management, analytical services, analysis and interpretation of data, report writing and presentation of results. GEOTECH provides exotoxicology consultancy and analytical services to many large and small clients with a rapid turnaround and high approval rating.

GEOTECH's Ecotoxicology Service occupies a controlled environment laboratory at the Aquaculture Development Unit in the WA Maritime Training Centre, Fremantle, Western Australia. This laboratory has been specifically designed to facilitate the performance of bioassays under a wide range of Western Australian conditions eg. temperate and tropical, freshwater, estuarine and marine.

The GEOTECH Ecotoxicology Service specialises in the development of chronic toxicity tests using species that are indigenous to the ecosystem receiving the pollutant. These tests can be used to determine the predicted effect of a pollutant on an ecosystem and to calculate a trigger value as recommended by the ANZECC Water Quality Guidelines (2000). GEOTECH's Ecotoxicology Service routinely performs chronic or sublethal bioassays; acute lethal tests can be performed if requested.

GEOTECH is the only ecotoxicology laboratory in Australia that has developed and validated a 7 day larval fish growth bioassay using several marine and estuarine species such as: pink snapper, black bream and mulloway.

GEOTECH performs toxicity tests on the following:

  Effluents
  Leachates
  Groundwaters
  Receiving Waters
