  • Water pollution · Canarina DESCAR software

    Natural waters contain micro-organism as well as solutes. There is a distinction between ‘pure’ water, meaning water that is fit to drink and pure water that is a single substance. A water pollutant is a substance that prevents the use of water for a specified purpose. The signs of polluted water are obvious. Poor drinking water tastes and smell bad. ...

  • Transboundary Pollution

    All pollutants can be transported through the aquatic environment and atmosphere, and many accumulate in downstream water bodies and their biota. The probability that pollution will cause transboundary impacts depends on the location of its source in relation to national boundaries, as well as the time it takes for a given pollutant to degrade. In general, microbial pollution is primarily a local ...

  • Atlas of America`s Polluted Waters

    The maps in this atlas depict the waters within each state that do not meet state water quality standards. States listed these waters in their most recent submission to EPA, generally in 1998, as required by section 303(d) of the Clean Water Act. This provision of the Clean Water Act requires a “Total Maximum Daily Load” or TMDL for each listed water. There are more than 20,000 such waters ...

  • Radiation treatment of polluted water and wastewater

    “Over 70 per cent of the Earth's surface is covered with water, but less than 3 per cent of that is freshwater — most of it locked up in glaciers, ice caps, the atmosphere and deep groundwater reservoirs.Just 13 per cent of the globe's total fresh water is readily available to meet human needs. In themeantime, worldwide demand for water is doubling every 21 years, according to the FAO. ...

  • Treatment of polluted river water by a new constructed wetland

    Abstract: A new constructed wetland was built to purify one polluted river in Taiwan, and this study was conducted to evaluate the treatment efficiency of the wetland. Due to the very limitation of available budget, several water quality items, which were stipulated by Taiwan’s Environmental Protection Administration for rivers, in the influent and effluent of wetland were analyzed and ...

  • Complex hydrocarbon pollutants in America`s Water

    Class action litigation continues to dominate the environmental news as it relates to MTBE (the cleaner previously used in gasoline), Perchlorate (primarily found in rocket fuel); and 1,4-Dioxane ( a widely used solvent) found in numerous State’s well and surface waters. Over 33-states currently have imposed their own regulations on MTBE, and the USEPA is reviewing what the Federal standard for ...


  • Cost-Effective Control of Interdependent Water Pollutants

    Abstract  Excess nutrient loads to coastal waters lead to increased production of algae, which when decaying cause oxygen depletion in bottom sediments, which in turn leads to major changes in marine ecosystems. A cost-minimization model was investigated in which nitrogen and phosphorus were assumed to interact with respect to algae production. It was investigated under what conditions only ...


  • River water pollution in Indonesia: an input-output analysis

  • Assessment of heavy metal pollution in surface water

    A total of 96 surface water samples collected from river Ganga in West Bengal during 2004-05 was analyzed for pH, EC, Fe, Mn, Zn, Cu, Cd, Cr, Pb and Ni. The pH was found in the alkaline range (7.21-8.32), while conductance was obtained in the range of 0.225-0.615 mmhos/cm. Fe, Mn, Zn, Ni, Cr and Pb were detected in more than 92% of the samples in the range of 0.025-5.49, 0.025-2.72, 0.012-0.370, ...
