Port Coogee irrigation water within safety guidelines
Released 16 Apr 2009
Monitoring data received by the department as a part of those conditions had revealed water used for public irrigation over the past 18 months, which was drawn from an approved drain, was within those guidelines.
"Port Catherine Developments (Australand) have a licence to use groundwater that comes specifically from a drain originally approved by the Environmental Protection Authority for the purpose of removing nutrient rich groundwater before it enters the marina, where it could potentially cause algal blooms and prove detrimental to the environment," the Department of Water's Director Water Resource Use Rob Hammond said.
"The licence has strict monitoring conditions that ensure the water meets irrigation guidelines.
"The chemical analysis of groundwater samples obtained from the drain so far as a part of those conditions, indicates that this water is acceptable to irrigation water guidelines.
"We have, on the other hand, received data from the development's monitoring bores which show potential for more varied results east of the drain including in some instances high levels of contaminants.
"Monitoring indicates that the water currently abstracted from the drain does not contain levels of contaminants found within these monitoring bores upstream and east.
On the information to hand, Mr Hammond said there monitoring bore results are an indicator of potential risk for residential bore use on the development.
"We issued this licence to draw water from the drain prior to the site being classified as contaminated by DEC," he said.
Mr Hammond said the Department of Water was working with the Department of Health to further analyse the irrigation water, as well as continuing to work with the licensee (Port Catherine Developments/Australand) to ensure the best outcome.
He said it was unfortunate that not every piece of land in the state was suitable for use of bore water.
"We have previously let the public know that for various reasons backyard bores are not always available to all people in all areas for many different reasons," Mr Hammond said.
