Gelita Australia Pty Ltd. has engaged ISR to assess the microbiological impacts of application of secondary-treated industrial wastewater for irrigation purposes as part of their environmental management system.
Microbiological monitoring of soils, irrigation water, groundwater and proximal surface waters to assess the transport of microbiological indicators (C. perfringens, E. coli and enterococci) from wastewater-irrigated pasture through groundwater and soils to proximal surface waters.
The survival and movement of indicator bacteria from treated-wastewater pasture is being used as a model for the transport of recycled water-associated microorganisms through typical Australian soils.
The data obtained will be of benefit to wastewater irrigators in SE QLD and allow a more informed assessment of the risks associated with such irrigation practices.
