Algal Management

AWQC has an extensive knowledge base and experience in the fields of algal/cyanobacterial taxonomy, ecology, toxicity and bloom management that has arisen from many years of research and development activities, transfer to operational monitoring programs and the delivery of consultancy services. AWQC is therefore well placed to provide expert interpretation of algal analytical results and advice on a broad range of algal issues. A recent initiative is the commencement in 2009/10 of a national "Cyanosurvey" funded by Water Research Australia and co-ordinated by AWQC. This investigation will develop a compendium of national data on cyanobacteria using a range of analytical methods in order to support an up to date risk assessment and to help predict future trends in species distribution and changes in toxicity.

AWQC has a proven track record in the investigation and resolution of water quality incidents involving noxious blooms of cyanobacteria in both potable and recreational waters for SA Water and other water authorities. The range of services that may be engaged include hydrodynamic modelling of water movement and water quality, the assessment of population growth dynamics and bloom potential from chemical and physical datasets, in situ fluorescence profiling of photosynthetic pigments (Chlorophyll and Phycocyanin) to determine the spatial distribution of blooms, evaluation of growth control strategies in source water and the effectiveness of cell, toxin and metabolite removal by water filtration processes. Examples of external consultancy services include in situ profiling of the 2007 cyanobacterial bloom in a Dam for a major interstate Water Authority and the evaluation of Phoslock treatment to control cyanobacterial growth in a Council lake area.
