Alkalinity is primarily a function of the carbonate, bicarbonate, and hydroxide concentration in the water. It's shown as the equivalent concentration of calcium carbonate, and the Australian Drinking Water Guidelines don’t have limits for health or aesthetics for it.
-
Part of the breakdown of the alkalinity measure, with no limits on health or aesthetics in the Australian Drinking Water Guidelines for it.
-
A measure of this naturally occurring element which can enter the water in the catchments. It’s sometimes added in the treatment process to make your water less acidic. The Australian Drinking Water Guidelines doesn’t have a limit on health or aesthetics for calcium.
-
Part of the breakdown of the alkalinity measure, with no health or aesthetic limits for it in the Australian Drinking Water Guidelines.
-
A measure of this naturally occurring element which can be present, usually in low levels, in South Australia’s surface water catchments. Higher concentrations are more common in groundwater systems. There’s no impact to the health of drinking water, but higher amounts – such as greater than the Australian Drinking Water Guidelines aesthetic limit of 250 milligrams per litre can change how the water tastes.
-
Filtration and treatment processes are designed to optimise removal of any colour from your drinking water, which can be caused by fine particles of natural organic matter or sediment present in source water. All South Australia’s drinking water systems are consistently lower than the national aesthetic limit for colour, which is 15 Hazen Units.
-
A type of microorganism most commonly found in human, dog, bird or other warm-blooded animal faeces, Escherichia coli (E. coli) is the most specific indicator of a recent faecal contamination, and if present in water it can cause illness or diarrhoea. E. coli in source water is destroyed by the disinfection processes and drinking water systems in South Australia are carefully managed to ensure there’s no E. coli bacteria present. If E. coli is detected in drinking water, through the extensive monitoring process, immediate corrective action is taken in conjunction with SA Health.
-
Fluoride is a trace mineral found naturally in water, soils and foods. It’s added to South Australia’s metropolitan and major country drinking water supplies, as mandated by our state health authority, because its proven to provide a significant public health benefit. Fluoride does not affect the taste, look or smell of your drinking water. All fluoridated drinking water systems are carefully monitored to ensure they pass the Australian Drinking Water Guidelines health limit for fluoride, which is 1.5 milligrams per litre.
-
The sum of the concentrations of calcium and magnesium ions shown as calcium carbonate equivalent. More than 200 milligrams per litre is considered hard water, usually more likely if you’re supplied mainly by groundwater systems, and can lead to scaling problems on your appliances and taps. If you have hard water you can find information about how to help protect your appliances.
-
A measure of this naturally occurring element present in water catchments. Although it’s safe to drink, higher than normal amounts of iron can sometimes discolour drinking water and change its taste. Our treatment and filtration methods may be altered accordingly, however, South Australia’s tap waters are consistently lower than the national aesthetic limit of 0.3 milligram per litre. There’s no health limit for iron in the Australian Drinking Water Guidelines.
-
Lead can be present in drinking water either because of dissolution from natural sources, or from any lead from your household plumbing systems (such as in pipes or solder used to seal joints). South Australia’s tap waters are consistently lower than the national health limit of 0.01 milligrams per litre. The amount of any lead in water depends on factors including pH, water hardness and standing time. Exceedance of acceptable lead levels are rare in South Australia, however if you are concerned or would like further information, SA Health provide advice about reducing lead in your home and in turn, your drinking water.
-
A measure of this naturally occurring mineral, essential to human health, which occurs in our water catchments. If concentrations of calcium and magnesium increase, so does the hardness of drinking water, however, there’s no health or aesthetic limit for magnesium in the Australian Drinking Water Guidelines.
-
Manganese is naturally present in the environment and is usually found in low levels in our drinking water supplies. At high levels it may affect taste of drinking water and discolour the water as well as affect pipes. All South Australia’s drinking water systems pass the Australian Drinking Water Guidelines limits for manganese, which are 0.5 milligrams per litre for health and 0.1 milligrams per litre for aesthetics.
-
A measure of the acidity or alkalinity of your tap water, where 1 is very acidic, 7 is 'neutral', and 14 is very alkaline. The national aesthetic limit is between 6.5 to 8.5, however if you’re drinking better tasting chloraminated water, your tap water may have a higher pH, and this is normal.
-
An essential element found in humans and rarely, if ever, found in drinking water at levels that could be of concern. There’s no health or aesthetic limits for potassium in the Australian Drinking Water Guidelines.
-
Chlorine is used in the water treatment process to protect public health and ensure water is safe to drink, destroying bacteria and other pathogens that can be present in source water. This is a measure of the amount of chlorine left in your water once all the demand has been satisfied – the amount remaining to further destroy any microorganisms. All South Australia’s drinking water systems are consistently lower than the national health limit for free chlorine residual of 5 milligrams per litre and all efforts are made to meet the aesthetic limit of 0.6 milligrams per litre.
-
Like chlorine, chloramine destroys bacteria and other pathogens that can be present in source water and ensures tap water is clean and safe to drink. This is the amount of monochloramine (NH2Cl) present, a mixture of chlorine and ammonia. Because chloramine is better than chlorine at penetrating longer pipes it’s used in longer water distribution systems across the state.
-
Chlorine is used in the water treatment process to protect public health and ensure water is safe to drink, destroying bacteria and other pathogens that can be present in source water. This is a measure of the amount of chlorine present in your tap water. All South Australia’s drinking water systems are consistently lower than the national health limit for total chlorine residual of 5 milligrams per litre.
-
Present in almost all water, food and drink. While remaining safe to drink, levels greater than the Australian Drinking Water Guidelines aesthetic limit of 180 milligrams per litre can change how your tap water tastes. These higher levels are more common in groundwater systems. There’s no national health limit for sodium.
-
A measure of this dissolved mineral which is present in South Australia’s water catchments. All our drinking water systems are consistently lower than the national aesthetic limit of 250 milligrams per litre. There’s no national health limit for sulphate.
-
A measure of inorganic salts and small amounts or natural organic matter (such as leaves, earth or sediment) which are dissolved in water. There’s no national health limit for this. Some of South Australia’s drinking water systems - mostly in regional areas - are higher than the national aesthetic limit of 600 milligrams per litre which affects taste.
-
Trihalomethanes (THMs) are by-products of disinfection, created when disinfectants added to protect public health (particularly chlorine) react with natural organic matter (such as leaves, earth and sediment) that can be present in source water. Drinking water systems in South Australia are carefully managed so that any concentrations of THMs are as low as possible, aiming to consistently be within the national health limit of 250 micrograms per litre, whilst ensuring the important disinfection process making water safe to drink is not compromised.
-
A measure of any presence of very fine particles in water, rarely found at levels that could be noticeable. At higher concentrations turbidity can mean your water could look discoloured, however it remains safe to drink. There’s no national health limit for turbidity, and all of South Australia’s drinking water systems are lower than the national aesthetic limit of 5 NTU.
-
Small amounts of zinc can sometimes be present if galvanised pipes/fittings and brasses are corroded, however, rarely found at levels in South Australian drinking water systems that would impact the taste of your tap water. There’s no health impact, and all of South Australia’s drinking water systems are lower than the national aesthetic limit of 3 milligrams per litre.
-
The sum of the concentrations of calcium and magnesium ions shown as calcium carbonate equivalent. More than 200 milligrams per litre is considered hard water, usually more likely if you’re supplied mainly by groundwater systems, and can lead to scaling problems on your appliances and taps. If you have hard water you can find information about how to help protect your appliances here. Hardness of water is generally used to help set up dishwashers. Depending on where your dishwasher was made, you may need this information in one of the following forms. Check your dishwater manual to confirm.

Expressed in French Degrees, the mineral content of your water (particularly calcium and magnesium ions).
-
Expressed in German degrees, the mineral content of your water (particularly calcium and magnesium ions).
-
Aluminium may be present in water through natural leaching from soil and rock, however there’s no risk to health, and no health limits are set out in the Australian Drinking Water Guidelines. If excess aluminium salts (for example, alum) are left over after they’re used as part of the cleaning and treatment process this can sometimes alter the water’s appearance, making it a slightly milky colour. We closely monitor the treatment process to ensure aluminium - acid soluble levels are as low as possible. The national aesthetic limit is 0.2 milligrams per litre.
-
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.
-
Can sometimes be present in drinking waters, usually in low concentrations, if there’s been contact with antimony-tin solder. All South Australia’s tap waters are consistently below the Australian Drinking Water Guidelines health limit of 0.003 milligrams per litre, and lead-based solders are no longer permitted to be used by licensed plumbers in Australia.
-
A naturally occurring element found in water, food and soil. It’s sometimes found in surface water, usually in low levels, but it can occur in higher levels in some groundwater sources. It can also be in water because of contamination from industrial waste such as mining and agriculture. We use specific treatment methods to remove arsenic from the water, and this ensures all South Australia’s tap waters are consistently lower than the national health limit of 0.01 milligrams per litre.
-

-
Like chlorine, chloramine destroys bacteria and other pathogens that can be present in source water and ensures tap water is clean and safe to drink. This is the amount of monochloramine (NH2Cl) present, a mixture of chlorine and ammonia. Because chloramine is better than chlorine at penetrating longer pipes it’s used in longer water distribution systems across the state. Plus, it makes the water taste better. All South Australia’s chloraminated water systems are consistently lower than the national health limit of 5 milligrams per litre.
