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 water testing in remote Aboriginal communities. Resources, training and support were provided by the Health Department of Western Australia to enable the 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 community 'water samplers'. A written survey of the participants (community water samplers), enabled their knowledge of the principles and the application of 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 training resources and to identify barriers to regular testing. Details of the support that was provided, was documented systematically during the trial by the Health Department. The participants were satisfied with the format and content of the training workshops. Support services documentation disclosed that contact with the participants throughout the trial was limited. The acceptance of the program by the water samplers varied. Those who participated 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 leaving the community. The specific outcomes of the program and directions for future programs are discussed.
