Unregulated, privately owned water supplies, including groundwater wells, are relied upon extensively, particularly in rural and remote regions. While adequate stewardship behaviors (water testing, treatment, and maintenance) have been shown to decrease the incidence and frequency of faecal indicator organism (FIO) presence and, by extension, the risk of pathogenic ingress, contaminated private water supplies continue to constitute a significant public health risk. Recognizing that innovative approaches are needed to bolster well stewardship, this paper identifies and assesses 35 tools (smartphone and web-based applications) to better understand components, functionality, strengths, and weaknesses. Applications for both data collection and risk communication were …

The aim of this study was to determine the physicochemical characteristics, thermal stability and release profile of ascorbic acid (AA) microcapsules obtained by complex coacervation. Gelatin and gum arabic were used as wall materials in concentrations of 2.5, 5.0 and 7.5 g% (w/v). The coacervate microcapsules were freeze-dried and assessed for physicochemical characteristics, thermal behavior and stability during 60 days of storage. The release profile was evaluated at different pH values (1.1, 2.2, 5.4, 7.4, 9.6 and 12). The encapsulation efficiency ranged from 27.3 to 93.8%. The microcapsules of AA presented good characteristics for application in food matrices, such as …
