  • Soil Particle Size Distribution

    Particle size distribution, also known as gradation, refers to the proportions by dry mass of a soil distributed over specified particle-size ranges. Gradation is used to classify soils for engineering and agricultural purposes, since particle size influences how fast or slow water or other fluid moves through a soil. Two proposed new ASTM standards provide test methods for determining particle ...

  • New silica method could reduce the cost of purifying drinking water

    Tiny particles of coated silica could be used to purify drinking water by removing harmful pollutants and pathogens. This simple and relatively cheap technology is capable of removing contaminants from water making it safe to drink and helping ensure that drinking water meets the standards of the European Drinking Water Directive. Provision of portable water is becoming a major socio-economic ...

  • Estimate soil texture-by-feel

    The ability to estimate soil texture-by-feel is an important skill that students and registered soil scientists should learn. Many soil properties depend largely on soil texture, and texture impacts most land-use decisions. Soil texture strongly influences the nutrient holding ability of a soil, the amount of water the soil can store, the amount of this water that is available to plants, how ...

  • Tracking down the menace in Mexico City smog

    A new report by scientists who are part of the international MILAGRO Campaign indicates that some of the most harmful air pollution in Mexico City may not come from motor vehicles but instead originates with industrial sources – and that the culprit may be garbage incineration. The MILAGRO Campaign (Megacity Initiative: Local and Global Research Observations) monitored air quality in the Mexico ...
