Lead Australian Drinking Water Guideline 0.01mg/L

“… Lead can be present in drinking water as a result of dissolution from natural sources, or from household plumbing systems containing lead. These may include lead in pipes, or in solder used to seal joints. The amount of lead dissolved will depend on a number of factors including pH, water hardness and the standing time of the water.

Lead is the most common of the heavy metals and is mined widely throughout the world. It is used in the production of lead acid batteries, solder, alloys, cable sheathing, paint pigments, rust inhibitors, ammunition, glazes and plastic stabilisers. The organo-lead compounds tetramethyl and tetraethyl lead are used extensively as anti-knock and lubricating compounds in gasoline…ADWG 2011

Bendigo/Spring Gully (Victoria) Nickel

25/1/18 Bendigo/Spring Gully Nickel 0.036mg/L

A sample, collected from the distribution system as part of Coliban Water’s sampling
program, had an elevated level of nickel (0.036 mg/L), exceeding the health-based guideline value for nickel (0.02mg/L) in the ADWG. The investigation undertaken has concluded that the nickel exceedance appears to be an unexplainable anomaly. It was an isolated incident and not an ongoing issue, and the probable cause of the elevated nickel result was contamination during sampling procedures.

Nickel: ADWG Health Guideline 0.02mg/L. A chemical element and silvery white corrosion resistant metal with a golden tinge. 60% of nickel production is used in nickel steel (particularly stainless steel). In water, mainly a problem with nickel plated fittings. Main releases to the environment are from the burning of fossil fuels and in waste discharges from electroplating industries.
