Process evaluation of an on-site water testing program in remote Aboriginal communities in Western Australia

A unique public health intervention introduced on-site water test kits into 19 communities in Western Australia in order to improve the frequency of w ater testing in remote Aboriginal communities. Resources, training and supp ort were provided by the Health Department of Western Australia to enable t he communities to conduct fortnightly water testing over a 12-month period. This study assesses how effective and appropriate the training and support strategies were, and the extent of acceptance of the program by the commun ity 'water samplers'. A written survey of the participants (community water samplers), enabled their knowledge of the principles and the application o f the test regime, and their satisfaction with both the training strategies and the resources to be evaluated. A structured phone survey was conducted mid-trial to re-assess participant knowledge, to ascertain the use of trai ning resources and to identify barriers to regular testing. Details of the support that was provided, was documented systematically during the trial b y the Health Department. The participants were satisfied with the format an d content of the training workshops. Support services documentation disclos ed that contact with the participants throughout the trial was limited. The acceptance of the program by the water samplers varied. Those who particip ated in the trial expressed the need for more feedback and support. A major reason for not participating in the trial was due to the water sampler lea ving the community. The specific outcomes of the program and directions for future programs are discussed.
