Ammonia - free - as NH3
Ammonia is added to some of South Australia’s drinking water systems which are chloraminated, a treatment ensuring your tap water is clean and safe to drink. There’s no health risk, so no national health limit. The Australian Drinking Water Guidelines sets an aesthetic limit of 0.5 milligrams per litre so that corrosion of copper pipes and fittings is prevented. Our drinking waters are consistently below this limit.
