Challenge Of Delivering Safe Drinking Water To The Developing World
Addressing the challenge of delivering safe drinking water to the developing world would be a major step forward in reducing the incidence of disease and increasing life span. In recent years, a growing number of innovative solutions have been fielded in an attempt to directly solve this problem; in fact H2Bid has featured many of these solutions as a part of this regular column. The devices range from mechanical to chemical in design with the common thread being the inventors striving to keep their solutions simple and easy to operate. Joining these solutions is perhaps the simplest yet: SODIS or Solar Water Disinfection.
Presumed effects of global warming on Water Sustainability
In July, 2010, the National Resources Defense Council (NRDC) released a report summarizing the presumed effects of global warming on water sustainability in the United States. NRDC worked with Tetra Tech, a consulting engineering firm specializing in waterways, water/wastewater management and environmental services.
Together, the NRDC and Tetra Tech analyzed current water usage and population trends then coupled that data with models of global warming that predict climate shifts for the United States. What they found may be cause for concern; over 1,100 counties in the United States may be at risk of water under-supply or sustainability by 2050.
