Risk assessment and recommendations for management of the Commonwealth Waters of the Ningaloo Marine Park.
Green Island (Queensland, Australia):
Evaluation and assessment of the impact of nutrient enrichments from septic tanks on the reefs and reef flats of Green Island. This included tracer studies, geomorphological assessment, biological monitoring and water quality monitoring and assessment to evaluate the ecological status of the system and to provide cost effective remediation and mitigation options for the island resort.
Groundwater Investigations and Assessments
Black River Borefield Investigation (Townsville, Australia):
Development of a detailed holistic analysis, assessment, interpretation and understanding of borefield sustainability for a Nickel Refinery.
Mount Stuart Training Area (Townsville, Australia):
Investigation into historical waste management and contaminant migration into groundwaters and subsequently into the designated emergency water supply. Knowledge of the complex interactions involved in these environments permitted cost efficient management decisions to be made.
Rollingstone Museum Wetlands Investigation (North Queensland, Australia):
Development of ground and surface water sampling regimes, saline water infiltration assessment and modelling, and site evaluation and monitoring programme including potential for off-site leaching into adjacent wetlands near Rollingstone Museum.
Geomorphological Investigations and Assessments
Breakfast Creek / Enoggera Creek (Brisbane, Australia):
Assessment of the relationships between riverine hydrogeomorphology and contaminant sources and sinks along a river profile.
Torres Strait Islands:
Numerous consultancies on beach erosion, impacts of climate change (wind and wave action variabilities), anthropogenic impacts on coastal erosion, and water composition. This included liaising with local Councils, Engineers, ATSIC, and GBRMPA.
Eimeo Road Upgrade (Queensland, Australia):
Investigations of environmental factors including geology, soils/sediments, geomorphology, ecology, water quality and hydrology. Remediation, mitigation and amelioration options were included.
Black River (Townsville, Australia):
Impact of large-scale industrial sand and water extraction, rural residential subdivision, and natural geomorphic processes, on the ecological and environmental sustainability of the river system. Environmental management risks were assessed and variable temporal remediation programmes indicated. Climate change impact was also evaluated and assessed.
Contaminated Sites and Soil Treatment
Fairfield Waters Development (Townsville, Australia):
Decontamination and in-situ bioremediation of contaminated soils for a large residential development.
Ross Creek Urban Renewal (Townsville, Australia):
Innovative strategies for urban renewal based on detailed chemical evaluation of contaminated areas adjacent to Ross Creek.
Spoil Site Investigations (Charters Towers, Australia):
Investigations of contaminant runoff from spoil sites in Charters Towers to provide estimates of metal contaminants entering the Burdekin River, Burdekin Dam, the designated water supply for irrigated farms in the Burdekin Delta and emergency water supply for the cities of Townsville and Thuringowa.
Environmental Data Interpretation and Analysis
North Mara River Iinvestigation (Tanzania):
Physical and chemical evaluation of the water column and bottom sediments, including sediment transport and flood potential investigations, identification of contaminants and a remediation programme.
Townsville Port Authority (Australia):
Investigations into sediment quality, remediation, disposal options, bioavailability and groundwater hydrology associated with contaminated sediment ponds.
Genetically Modified Crop Investigation (Moree, Australia):
Investigation of water runoff compositions from genetically and non-genetically modified cotton fields.
Environmental Legislation and Compliance
Development Approvals (Magnetic Island, Australia):
Development Applications under the Integrated Development Approval System (IDAS) for various developments on a World Heritage listed island adjacent to areas protected by international treaty. Developments were assessable against Local, Regional, State, Federal and International Legislation.
Magnetic Island Pipeline (Cleveland Bay, Australia):
The pipeline crossed a number of environmentally sensitive locations including a Dugong Protected Area (DPA), a coral reef flat, and a reasonably extensive mangrove system with significant Potential Acid Sulphate material (PASS). Methods of impact minimisation were developed to provide a workable construction programme acceptable to all levels of government, and compliant under all relevant legislation.
Orpheus Island Research Station (Orpheus Island, Australia):
Orpheus Island Research Station is a World Class environmental research institution situated in a National Park within a World Heritage Area and Marine Park. It is, therefore, subject to a complex series of State, Federal and International Treaty obligations. All these requirements were met and suitable compliance and auditing procedures established.
Geographical Information Systems and Geo-Referenced
