All available ambient data from water quality monitoring in drainage basins by the Queensland Department of Science Information Technology Innovation and the Arts.
Lineage: The current data are derived from fieldwork conducted by staff of the Environmental Monitoring and Assessment Sciences Unit within the Queensland Department of Science Information Technology Innovation and the Arts for SEQ as part of the Estuarine and Marine component of the Moreton Bay Ecosystem Health Monitoring Program (EHMP) and in Central Queensland as part of the Central Queensland Ambient (CQA) Program. EHMP is an ongoing ambient monitoring program established in 1999 by the Moreton Bay Waterways and Catchments Partnership (the Partnership) as a recommendation of the task Design and Implementation of Baseline Monitoring (DIBM) with the role of independently assessing the management actions undertaken within the South East Queensland Regional Water Quality Management Strategy (SEQRWQMS) which was initiated in 1993 as the Brisbane River and Moreton Bay Wastewater Management Study (BR&MBWMS) and consistent with the National Water Quality Management Strategy (NWQMS). The NWQMS is jointly administered by the Agriculture and Resource Management Council of Australia and New Zealand (ARMCANZ) and the Australian and New Zealand Environment and Conservation Council (ANZECC). The National Health and Medical Research Council (NHMRC) is involved on health matters. The NWQMS recognises that on-going management and protection of water resources is essential for the continuing viability of most sections of our society. The NWQMS is based on the principles of the National Strategy for Ecologically Sustainable Development. The EHMP sites in SEQ generally follow on from the Queensland Statewide Ambient Water Quality Monitoring Program sites designed, approved and funded by the Queensland Department of Science Information Technology Innovation and the Arts and underway from 1992. The core EHMP was functioning from February 2000 with the second phase or expansion of EHMP from October 2002.
Field maps for the water quality monitoring program were used as guides to digitise each water quality monitoring location. Attributes such as date, time, depth below the water surface, pH, specific conductance, dissolved oxygen, turbidity and temperature are both recorded manually by the field staff and captured by data logger. A range of internal quality assurance procedures cover sample collection, sample preservation, sample storage through to laboratory analysis with electronic transmission of laboratory results to the Queensland Waterways Database with manual validation checks of the data. The majority of laboratory analyses are conducted by the Queensland Health Scientific Services, with the laboratory analysis of chlorophyll-a being conducted in-house
