  • Algae Control in Lakes and Reservoirs

    There are plenty of harmful algal bloom related cases worldwide but what is evident is that their number elevates with each year. Excessive cyanobacteria (blue-green algae) and green algae growth in a water reservoir can have negative consequences for the water quality. The water turns green, sand filters can clog, and some algae can produce geosmins and MIB, giving the water an ...

  • Lake Water Quality Model with Focus on Cyanobacteria

    ABSTRACTThe cause of cyanobacteria’s growth and dominance in certain eutrophic lakes is explored via a water quality model application. The one-dimensional lake water quality model includes nitrogen, phosphorus, silica, three phytoplankton groups and zooplankton. Lake Washington was used as the case study due to its unique history of eutrophication during a large wastewater nutrient loading ...

  • Urban Lakes

    BritishFlora's expertise in delivery of cost-effective Remediation of Urban Lake. For years fish had been dying in the dirty, silted waters of Bracknell Mill Pond. When Bracknell Town Council, in partnership with Thames Water and the Environment Agency, resolved to transform this operational flood storage lagoon into a flagship wildlife and recreation resource, no one was more pleased ...

  • Physical, Chemical and Microbiological Water Quality of the Manyas Lake, Turkey

    Manyas, also known as the Bird Paradise Lake, is situated near the south-eastern coasts of the Marmara Sea in Turkey. This shallow lake, is a unique natural reserve providing habitat for migratory birds with its rich fauna and plankton species. The objective of this work is to study the ecological and water quality changes resulting from increasing anthropogenic pollution and human intervention ...

  • Microbial water quality of recreational lakes near Tbilisi, Georgia

    Microbial safety of recreational water is one of the major human public health issues in developing countries. Three water bodies, the Tbilisi Sea, Kumisi and Lisi lakes, in the South Caucasus region near Tbilisi, Georgia, were monitored in 2006–2009 to determine microbiological quality using standard methods. Microbial pollution indicators were determined in parallel with phytoplankton ...

  • Development of water scenarios for large lakes in Europe: the case of Lake Peipsi

    Qualitative or quantitative description of the future by developing scenarios is a key method when taking a long-term view, e.g., up to 2050. Previously the time frames covered by the scenarios have usually been no more than 20 years. This period can be too short for achieving long-term goals when, for example, testing watershed management plans. This paper is an attempt to introduce and ...

  • Skaneateles Lake Demonstration Project

     ABSTRACT The Skaneateles Lake Demonstration Project was established to demonstrate the use of commercially available alternative onsite wastewater treatment technologies in the Skaneateles Lake watershed to protect public health, maintain drinking water quality, and sustain the environment. Alternative onsite wastewater ...

  • Lake Edku water-quality monitoring, analysis and management model for optimising drainage water treatment using a genetic algorithm

    Lake Edku, one of the northern Nile Delta Lakes, subjected to huge inputs of nutrients (especially phosphorous and nitrogen). These nutritional conditions create rich resource spectrum for algal growth and make the lake suffer from high level of eutrophication. Lake Edku does not have numeric water quality criteria for nutrients. The main objective of this research is to develop a model which can ...

  • Development of a macroinvertebrate-based Nepal Lake Biotic Index (NLBI): an applied method for assessing the ecological quality of lakes and reservoirs in Nepal

    In Nepal, the impairment status of lakes and reservoirs has generally been measured and classified based on nutrient concentrations and physico-chemical parameters, typically with no direct measurement of biological communities. In response to the recent focus on the bioassessment of lakes and reservoirs, the macroinvertebrate-based Nepal Lake Biotic Index (NLBI) has been developed. Benthic ...

  • Development of the Sleeper Pit Lake

    The Sleeper open pit gold mine operated from the mid-1980s through the mid-1990s. Operations were mostly sub-water table and extensive dewatering was required to lower groundwater levels by 180 m. Dewatering flows peaked at 930 L/s, with most flow contributed from an alluvial aquifer. After completion of mining, the pit was rapidly filled with water pumped from the alluvial aquifer to reduce the ...

  • Hydrogeomorphological Controls on Groundwater Quality in the Rattaphum Catchment (Songkhla Lake Basin), Thailand

    The Rattaphum Catchment comprises four major hydrogeomorphic units: mountains, footslopes, plains and inland swamps around a lake system. The area accommodates three main agroecosystems: vegetable, rubber and fruits. During the high-rainfall period, groundwater levels rise near to the soil surface in all agro-ecosystems. The high water levels remain for 3–4 months in the coastal plain, while in ...

  • Lake Jamno remediation proposal

    Lake Jamno………. near the city of Koszalin in Poland, has been contaminated by bio-mass sludge build-up from many years of agriculture run-off. Once a popular recreational and vacation destination, the Lake has been closed to swimming and boating since 2001. A Letter of Intent has been signed between the City of Koszalin and BluePlanet for the reclamation of Lake Jamno using an AQUACLEAN Treatment ...

  • Cladophora in the Great Lakes: impacts on beach water quality and human health

    Cladophora in the Great Lakes grows rapidly during the warm summer months, detaches, and becomes free-floating mats as a result of environmental conditions, eventually becoming stranded on recreational beaches. Cladophora provides protection and nutrients, which allow enteric bacteria such as Escherichia coli, enterococci, Shigella, ...

  • Water Quality Models

    ' In order to determine the impacts of a particular discharge on ambient water quality, it is usually necessary to model the diffusion and dispersion of the discharge in the relevant water body. The approach applies both to new discharges and to upgrading of existing sources. This note provides guidance on models that may be applicable in the context of typical Bank projects.' Introduction ...

  • Waste systems for lake and coastal development

    Abstract Because of site specific factors such as clayey soils, excessive slopes. seasonal soil wetness, and rapid "perc" sands, the conventional septic tank-soil absorption system has had a high rate of malfunctioning in lake and coastal shore developments. Because of high density of development in close proximity to these waters of Texas, alternative systems were needed which offer ...

  • July is Lake & Reservoir Awareness Month!

    Lakes and reservoirs cover over 40 million acres of the United States. Lakes and reservoirs also play other vital and often hidden, roles. They provide drinking water and irrigation water for agricultural fields and many times a source of electricity and power generation. They also serve an important function of absorbing rainfall and runoff from land, help to prevent floods, and provide ...

  • European bathing water quality in 2012

    Every year, millions of Europeans take advantage of the continent's wonderful selection of beaches, rivers, and lakes for a relaxing holiday or a day out. It is vitally important that they know the quality of the water they are swimming in, and that they do not jeopardise their health. The European Environment Agency (EEA) and the European Commission hope that this year's bathing water report ...
