  • Integrating quality and cost of surface raw water: Upper and Middle Vaal Water Management Areas South Africa

    The user-pays principle encourages use of a water tariff structure that incorporates pollution and/or depletion of a water resource because that water represents a capital resource base. Development of a tool that models variability of surface raw water quality in order to predict cost of treatment thus makes economic sense. This paper forms the backbone for an on-going doctoral study in South ...

  • 12 strategies for moving from water scarcity to abundance

    How did a country that’s 60 percent desert achieve water security? In about 10 years, beginning shortly after the new century, Israel went from scarcity of water and fear of drought to abundance and independence from climate conditions. This dramatic change was made possible by the 70 years that preceded it in which a cadre of often brilliant engineers, scientists and ...

  • IAQ UPDATE: Using an Infrared Camera to Detect Water and Mold Problems

    A low temperature range infrared camera is a very useful tool in detecting the presence of water or moisture that ultimately leads to mold growth. Infrared or thermal inspection does not directly identify the presence of mold, but it may be used to find moisture where mold may cultivate, especially behind wall board. But Beware!  I have seen many cases where the infrared camera results have ...
