EVEN if Bundaberg residents do test high for PFAS, there is nothing they can do.
"Investigations are taking place to find the source of the contamination here in Bundaberg," Dr Young said.
Dr Young said the level of PFAS the community was exposed to was low and "genuinely believed the risk to Svensson Heights residents was also low".
Dr Young said anyone in Svensson Heights with concerns could take up the option to have their blood tested through their GP.
"We know in any chemical if it gets to a high enough level that it can cause problems," she said.
"We don’t know what that level is for PFAS."
"The long term health consequence we are not sure about, which is why we want people to stop consuming it.
Dr Young said 32 people had phoned 13 Health, so far, with concerns about medical issues relating to PFAS.
Dr Young agreed that people in Bundaberg could have been drinking the contaminated water for more than 50 years.
"If everyone in the world continued to use this for the next 50 years we would gradually see an accumulation," she said.
