​Fremantle Ports undertakes a comprehensive annual Marine Quality Monitoring Program (MQMP). It forms part of our overall Environmental Management System and allows us to assess any port-related environmental impacts and guide appropriate management actions. The results are provided to Cockburn Sound Management Council and the Department of Water and Environmental Regulation.

Fortnightly monitoring

Water sampling occurs at two Fremantle Harbour locations and one upstream site as an extension to the Swan River Trust / Department of Water Swan River Estuary monitoring program. Parameters measured include depth, salinity, temperature, dissolved oxygen, pH, turbidity, nutrients and chlorophyll.

Annual monitoring

There are 29 sample sites located in the Inner Harbour, shipping channels and Cockburn Sound. Mussels are tested for tributyltin (TBT), hydrocarbons, heavy metals and coliform bacteria.

 Divers collect sediment cores which are tested for nitrogen, phosphorus, heavy metals, tributyltin, hydrocarbons and organochlorine pesticides.

Water profiles are taken for temperature, salinity, dissolved oxygen and pH. Water clarity is recorded through the use of a secchi disk. Surface and bottom water samples are taken and tested for total suspended solids, nutrients, alkalinity, chlorophyll, copper and hydrocarbons.
