Australian Drinking Water Guidelines: Draft fact sheet on lanthanum

Closed on Friday, 4 November 2016, 11:59pm (AEDT). Submissions are no longer being accepted.

Lanthanum public consultation

NHMRC is seeking public comment on the draft fact sheet on lanthanum. You are invited under paragraph 13(d) of the NHMRC Act 1992 to make a submission to NHMRC about this draft.

Issues raised during public consultation will be considered by the Water Quality Advisory Committee (WQAC) in finalising the fact sheet. The fact sheet will then be published as part of the Australian Drinking Water Guidelines (ADWG).


Lanthanum is a chemical element, which when bound to bentonite clay may be applied to bodies of water to reduce excessive nutrients (phosphate), with the aim of reducing algal blooms (e.g. cyanobacteria). It may be used in recreational water and in drinking water supplies.

The ADWG contains fact sheets and guideline values for a number of chemicals that might be present in drinking water. The guideline value for each chemical is the concentration that, based on present knowledge, does not result in any significant risk to the health of the consumer over a lifetime of consumption and is consistent with water of good quality.

NHMRC has worked with the National Industrial Chemicals Notification and Assessment Scheme to develop this draft fact sheet.

Issues raised during public consultation on other aspects of the ADWG or water quality will not be considered through this process
