Most of us drink bottled water or tap water out of reused plastic bottles with the average Australian drinking 30 litres of bottled water a year.
The levels of bacteria and toxins lurking inside those bottles can be shocking.
There were more than 300,000 germs for every square centimetre inside the bottles – 100 times more than a pet toy.
Yet experts have revealed if the bacteria has derived from the same person who drinks from the bottle, the risk is low.
“The germs that are in bottled water – they’re germs that come from us,” University of NSW Professor Stuart Khan revealed.
“The concentrations that we come across are well below concentrations that there’s any evidence at all are going to cause human illness,” Professor Khan said.
A safe level of antimony, a toxin used in plastic production, is 6ppb (concentration level).
Scientists says it’s like arsenic.
If you look hard enough, you’ll find traces of the chemical in spring water, however not enough to cause concern.
Edging towards a one billion dollar industry, Australia’s thirst for bottled water only grows.
