Silica - reactive
Silica is a naturally occurring and common mineral that forms the major component of most rocks and soils. It’s naturally present in surface water, usually in low levels, but can occur in higher levels in some of the state’s groundwater sources. There’s no national health limit for silica in drinking water, however, because it can cause unwanted build up on glass surfaces, the Australian Drinking Water Guidelines sets an aesthetic limit of 80 milligrams per litre for it.
