NEWS NOTES ON SUSTAINABLE WATER RESOURCES  Potable Fog and Dew  https://agupubs.onlinelibrary.wiley.com/doi/pdf/10.1029/2018GH000171 ;   Kudzai F. Kaseke and Lixin Wang, Fog and dew as potable water resources –maximizing harvesting potential and water quality concerns , Department of Earth Sciences, Indiana University-Purdue University Indianapolis, Indianapolis, Indiana, USA, Oct. 2018.  Fog and dew are often viewed as economic nuisances causing significant financial losses in the transportation industry and agricultural sector. However, they are also critical components of the hydrological cycle especially in water scarce environments. Water scarcity is one of the major threats to mankind in the 21st century, and this can be due to development pressures, pollution and/or expanding populations.  In water scarce environments, fog and dew represent potentially exploitable ancillary water resources that could ameliorate the water scarce situation, if efficiently harvested. However, two important issues are often overlooked in relation to fog and dew harvesting and potability. First, current fog and dew harvesting technologies are low yielding with great potential for improvements. Second and more importantly, the potability of these water resources is often based on simple analyses that often omit trace metal and biological analyses. The few studies that report trace metal or biological measurements suggest elevated trace metal concentrations or biological contamination that could be of concern to public health. We discuss the potential for fog and dew harvesting technologies and the need for trace metal and biological analyses of these waters before use.  This study will also be linked on the 2018 Reports Page 02 of the Sustainable Water Resources Site at https://sites.google.com/site/sustainablewaterresources/ ">https://sites.google.com/site/sustainablewaterresources/ ; Tim SmithSustainable Water Resources CoordinatorGovernment Web Site, https://acwi.gov/Sustainable Water Resources Site, https://sites.google.com/site/sustainablewaterresources/ ">https://sites.google.com/site/sustainablewaterresources/ ;
