Lead in tap water a potential health hazard

Lead levels in tap water may be a public health hazard, say NSW researchers, who found that some households tested nine times the recommended limit.

Researchers from Macquarie University in Sydney tested drinking water in 212 houses across the state and found that 8% contained excessive levels of lead.

Australian Drinking Water Guidelines state that 10ug/L per litre is the recommended limit for lead levels, but 17 houses tested above this level, including some that tested up to 90ug/L.

The source of the contamination was the high lead content of brass components in modern tap fittings
