Tasmanian residents have discovered that their tank water is contaminated with toxic chemicals due to the lead paint of their roof running into their water supply. 

Documents show the state’s water authority, TasWater, were aware that some people had too much lead in their roofs, but connected the water tanks anyway, which sparked concerns that residents had been exposed to unsafe lead in water for years.

Water was deemed unfit to drink in 2012, forcing residents to live off bottled water, and while TasWater has said they will replace old roofs, those affected are unsure of when this will take place.
