  • Anaerobic Digestion Reduces Microplastics in Sludge

    Anaerobic digestion can help remove microplastics — a large cause of water pollution — during the sewage treatment process Microplastics, or tiny fragments of plastic, include microbeads, the plastic pellets present in thousands of household and personal care products, including toothpaste, cosmetics, and beauty scrubs. They also include fragments from the breakdown of anything in our ...

  • Oysters act as a natural seawater filtration system

    Environmental educators in Pensacola are acquainting kids with water filtration in a new, hands-on way. Instead of a class turtle, these students are raising baby oysters. This program is sponsored by the Pensacola Bay Oyster Company and supports a local nonprofit, the Bream Fisherman Association, in its efforts to ...

  • Water Pollution

    Water pollution is a major global problem that requires ongoing evaluation and revision of water resource policy at all levels (from international down to individual aquifers and wells). It has been suggested that it is the leading worldwide cause of deaths and diseases, and that it accounts for the deaths of more than 14,000 people daily. In addition to the acute problems of water pollution in ...

  • Chemical pollutants in water emerge

    Recent advances in contaminant identification methodologies, sampling instrumentation, and analytical chemistry have caused an explosion of knowledge about the presence of previously undetected organic micropollutants. While it doesn"t follow that the mere presence of chemical contaminants results in harm, public health experts, regulators, and others aren"t sitting idly by. Given the necessity ...

  • Bioremediation of pollutant-contaminated water

    Raw water resources in Kafr El-Sheikh Governorate are affected by many contaminants particularly during the winter season and low demand period of the Nile River, in which water level decreases and organic matter increases resulting in decreased dissolved oxygen, and increased ammonia, nitrite and bacterial load in the water. In this study, physicochemical and microbiological characteristics ...

  • 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. ...

  • 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 ...

  • 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. ...

  • 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, ...

  • A hydrodynamic water quality model for propagation of pollutants in rivers

    Numerical modelling can be a useful tool to assess a receiving water body's quality state. Indeed, the use of mathematical models in river water quality management has become a common practice to show the cause-effect relationship between emissions and water body quality and to design as well as assess the effectiveness of mitigation measures. In the present study, a hydrodynamic river water ...

  • Pollution of south of Tehran ground waters with heavy metals

    Abstract: The reuse of nutrients and organic matter in wastewater sludge via on agricultural lands application is a desirable goal. However, trace or heavy metals present in sludge pose the risk of human or phytotoxicity from land application. The aim of this research is possibility of ground water pollution of south of Tehran because of ten years irrigation with Ni, Cd and Pb borne waste water. ...
