“Pathogens can enter the water system either at the source (before treatment) or after treatment (in the pipes delivering it to you) through direct faecal or human contact with the water, sewage leakages, stormwater run-off after rain and animal droppings,” says Dr Helen Stratton, senior lecturer at the Smart Water Research Centre at Queensland’s Griffith University.
Its effects You may recall the most publicised drinking water contamination incident in Australia in 1998, when high numbers of organisms, giardia and cryptosporidium, were reported in Sydney’s treated water – three million residents were advised to boil their water to avoid diarrhoea.

If you live in a home built before the 1930s, chances are your pipes contain lead, plus lead-based solders were used on copper pipes until as recently as 1989. But don’t go re-piping your house – the NHMRC says we get more lead from food, dirt and dust than water.
Its effects For some, a small amount of lead is bad news; it’s a cumulative poison that can attack your nervous system, and it’s been linked to things like irritability, anaemia, kidney damage and cancer.
A study in Environment International linked childhood lead exposure to violence in adulthood. If you’re trying to conceive you should also be careful – research over the years has linked lead poisoning to miscarriage and foetal complications.

“[Water treatment plants have] several options to greatly reduce the levels of drugs in water,” says Dr Frederic Leusch, program leader of Water Quality and Diagnostics at Griffith University.
“These techniques are 99.99 per cent effective, which means that they will remove the great majority of drugs and other chemical pollutants [like pesticides] from water sources, but a tiny little bit will always be left in.”
Its effects The NHMRC says that no definitive link has been established between drug exposure in drinking water and health problems, probably because traces are so low: “For example, [paracetamol] has been detected at up to 45 nanograms per litre in drinking water,” says Dr Leusch.
“At that concentration, you’d have to drink two litres of tap water every day for 30,000 years to ge...
Some reports, including one by the University Medical Center Freiburg in Germany, have raised alarm bells over antibiotics in water supplies potentially leading to the development of superbugs, yet the NHMRC says studies are yet to confirm this.
Your action plan Many household filters don’t stop drug residuals, so watch this space: worldwide investigations into drugs in drinking water are ongoing.
