  • Things You Should Know about Your Reusable Water Bottle

    Reusable water bottles are everywhere; on office desks, in gym bags, and in kids’ backpacks. And while it’s inexpensive, environmentally friendly, and incredibly convenient to stop by any tap or fountain for a quick refill, there are a few things to remember about these reusable bottles. Actually, there are a few things to remember about microorganisms: many of them love warmth, ...

  • Investigating the management of unaccounted for water for Lilongwe Water Board, Malawi

    Lilongwe Water Board (LWB) is currently unable to meet Lilongwe City's water demand as evidenced by low supply coverage (65%) and intermittent water supply in the city. One of the major challenges is high levels of unaccounted for water (UFW) reported at 37% (2012), higher than the recommended 23% for developing countries. This study, done in Lilongwe City (Areas 15, 18 and 28), investigated ...

  • Community water fluoridation predicts increase in age-adjusted incidence and prevalence of diabetes in 22 states from 2005 and 2010

    Community water fluoridation is considered a significant public health achievement of the 20th century. In this paper, the hypothesis that added water fluoridation has contributed to diabetes incidence and prevalence in the United States was investigated. Panel data from publicly available sources were used with population-averaged models to test the associations of added and natural fluoride ...

  • Improved estimate of multiyear drought for water resources management studies

    Using short hydrological records to characterise extreme drought for water studies could lead to uncertain results. At first, this article introduces a generic model that extends the length of short hydrological records to improve the analysis of drought. Using simulated data, the extension model performance was tested and found to work well and later the model was used to extend the annual ...
