The 1945 - 1955 Queensland Artesian Fluoride Experience: A Unique Phenomenon within the Australian Wool Industry

Abstract

Inquiries into the diminishing supply of artesian water within the Queensland aspect of the Great Artesian Basin began in 1939. These investigations produced a Queensland phenomenon without Australian precedent in terms of rationale, geographical diversity, and commitment of resources. In some regions, exposure of herds to fluoride emerged as an urgent issue because fluoride was perceived as an invasive, invisible, and odourless 'contaminant' in artesian water. This paper discusses the scientific background to, and management of, concerns over the consumption by stock of artesian water with a high concentration of natural bioavailable fluoride. The Queensland Department of Agriculture and Stock managed the problem by scientific investigation, methodical field study, and the application of research findings to animal husbandry. The practical solutions arrived at involved rotation of stock on an age-related basis to and from certain bore supplies, fencing young sheep away from the artesian supply, fencing young sheep near the bore-head, and limiting the use of supplements.
