The EPA has established an environmental quality management framework for Cockburn Sound, which has been given effect through the State Environmental (Cockburn Sound) Policy 2015 (Government of Western Australia, 2015). The framework is underpinned by established environmental values and clearly expressed and spatially defined environmental quality objectives to guide decision-making and provide the common goals for management.

Several water quality surveys were undertaken in the coastal waters of the Kimberley region from September 2007 to August 2008 to measure typical TSS concentrations and determine background total and dissolved concentrations of aluminium, arsenic, cadmium, chromium, cobalt, copper, lead, mercury, nickel, silver and zinc. This work was undertaken to establish a baseline for the Kimberley from which to assess local and regional changes in water quality in years to come and to ascertain whether the guideline trigger values from ANZECC & ARMCANZ (2000) are relevant to the region.

Following a blowout at the Montara wellhead platform on 21 August 2009, petroleum hydrocarbons flowed effectively unabated into the Timor Sea, approximately 175 kilometres (km) from Western Australian coastal waters, until the leak was contained on 3 November 2009. This report presents findings of a petroleum hydrocarbons survey conducted in July 2010 as part of the response to the Montara incident.

A water quality survey was undertaken in December 2008 at two locations on the Western Australian Kimberley coast that were shortlisted as potential sites for the construction of an LNG processing precinct. Water samples were collected and processed to determine total suspended solids (TSS), chlorophyll a, b and c, ammonia, total phosphorous (P), total nitrogen (N), nitrate plus nitrite (NO3+NO2) and orthophosphate concentrations at selected sites across both study areas.

A report for the Department of Environment and Conservation as part of the Swan Bioplan Project. Authors:BJ Keighery, GJ Keighery, A Webb, VM Longman and EA Griffin (April 2008)

A survey of the Whicher Scarp was undertaken by the Departments of Environmental Protection and Conservation and Land Management together with the Wildflower Society of Western Australia (Inc.) over a period of more than 10 years. This work was completed as part of the Swan Bioplan Project to provide a more detailed knowledge of the conservation status of species and communities that occur in this area.
