More than 70% of the earth’s surface is covered by water, most of which has been impacted by human practices to some extent. Water bodies such as lakes, rivers, and oceans support a diverse array of aquatic life. With the increasing concerns over water contamination by land activities, the importance of water quality is paramount in supporting aesthetic, recreational, commercial and ecological values. Ecosure’s assessments of water quality and ecology can provide useful information for managers to improve water quality and aquatic habitats.
Ecosure takes a multidisciplinary approach to water quality management. We assess physico-chemical characteristics and also biological components to provide a holistic picture of the ecological status or ecosystem health.

Our Projects
Water Quality Monitoring Program, Resolute Mine, Carpentaria Gold and Coffey Environments
Our aquatic team performed an assessment of baseline aquatic ecology, water quality and sediment quality at a proposed central Queensland gold mine expansion. Additional water quality and aquatic ecology assessments were undertaken with the intention of revising and renegotiating water quality compliance triggers with DERM. We developed a water quality and groundwater quality monitoring and assessment program and biological program to assess improvements in ecosystem health associated with improved site management.
Water Quality Monitoring Program, Gold Coast Airport Pty Ltd
Ecosure have carried out the water quality monitoring program for Gold Coast Airport waterways since 2001. This involves frequent monitoring of groundwater quality, surface water quality, fish and invertebrates. Field and laboratory parameters are monitored for compliance against the Airports Environmental Protection Regulations (1997) as a requirement of the Airports Act 1996. Information on water quality coupled with biological indicators provides information on ecosystem health. Ecosure conduct the sampling, arrange for laboratory analysis (Simmonds and Bristow), and prepare quarterly and annual reports.
Johns Pit Discharge Project, Northgate Minerals
Our team completed water quality and aquatic ecology assessments to determine the capacity of a receiving environment to accept licensed discharge from a gold mining operation. We developed a downstream dilution model that can be used by mine operators to quickly determine the rate of discharge that can be released to the river whilst complying with EPP’s and ANZECC trigger guidelines for key parameters.
Water Quality Monitoring Program, Townsville Airport Pty Ltd
Ecosure conducts water quality monitoring for Townsville Airport. This involves seasonal monitoring of groundwater quality and stormwater (event) sampling. Results are compared against the Airports Environmental Protection Regulations (1997) as a requirement of the Airports Act 1996. Ecosure collect the samples, arrange for the laboratory analysis (Australian Centre for Tropical Freshwater Research), interpret the results and prepare the reports.
Lake Lomandra Management Plan, Gold Coast City Council (GCCC)
GCCC commissioned Ecosure to undertake an ecosystem health analysis of Lake Lomandra, an urban lake on the southern Gold Coast. The project involved a number of tasks including water quality assessment, stormwater assessment and modelling, aquatic vegetation, algal investigations, public consultation and awareness. Recommended actions were developed which included prioritized, issues, implementation costs, and agency responsible for implementation.
Hinze Dam Stage Three (HDS3) Environmental Impact Statement (EIS)- Aquatic Ecology component, Hinze Dam Alliance (SKM)
Ecosure in collaboration with Aquateco completed the aquatic ecology aspects of the EIS prepared by the Hinze Dam Alliance. This involved intensive surveys using a variety of techniques to establish the macroinvertebrate, fish and aquatic flora species present in both its upper and downstream reaches and within the Dam. We assessed instream and in-lake habitat and investigated sediment characteristics.
Compliance Monitoring for Gold Coast Airport Runway Extension Project, Gold Coast Airport Pty Ltd
Ecosure were contracted to monitor environmental compliance against the Construction Environmental Management Plan (CEMP) for the Gold Coast Airport Runway Extension Project. Ecosure provided the Environmental Compliance Officer who conducted water quality monitoring on a bi-weekly basis of both surface and groundwater, reported on air and noise monitoring as well as other environmental aspects such as sediment and erosion control. Fortnightly reports were prepared that compared results to the performance criteria as specified in the CEMP.
Saltwater Park Environmental Assessment, Gold Coast City Council (GCCC)
Ecosure carried out an environmental assessment of Saltwater Park to provide aquatic and terrestrial flora and fauna mapping and recommendations regarding legislation, rehabilitation and management of the park. This assessment was undertaken in the context of the Saltwater Park upgrade project. Ecosure conducted field based flora, fauna and aquatic surveys to identify areas within the park that yielded highest environmental values. The results were used in the design of the Park upgrade to enhance areas with highest ecological values.
Currumbin Creek In-stream Baseline Assessment, Gold Coast City Council (GCCC)
Ecosure, in collaboration with Aquateco, carried out a baseline in-stream survey of a section of Currumbin Creek where stream rehabilitation works were planned. Surveys involved water quality, using a variety of techniques to establish water quality, macroinvertebrate, fish and aquatic flora species present in both test and reference sites within the section of the Creek. The results provided baseline indicators of stream health for which future monitoring can be compared and the success of the rehabilitation works can be measured.
Green Heart Reserves Instream Assessment, Gold Coast City Council
The scope of this project was to carry out a basic ecological site assessment to provide a baseline inventory of aquatic ecological features and functions within the Green Heart Reserves. It included an assessment of potential impacts on the study area from construction and operation identified in the Green Heart Reserves concept plan. It also included a GIS mapping component.
Cobaki Broadwater Bio-accumulation Study, Gold Coast Airport Pty Ltd
Ecosure in collaboration with Aquateco carry out this study which has three main facets: characterisation of sediments within the Broadwater, mapping aquatic habitats and assessment of oysters for bioaccumulation of potential contaminants. The primary objective is to identify any change in the above facets that may arise from catchment activities.
Rapid Assessment of Riparian and In-Stream Condition, Gold Coast City Council
Ecosure were involved in development and implementation of a rapid assessment method to assess in-stream habitat, bank condition including erosion extent, riparian vegetation and water quality of freshwater tributaries of the Coomera River catchment.
