  • Water quality monitoring following Hurricanes Katrina and Rita

    Following the passage of Hurricane Katrina, New Orleans was left with 80% of its land area flooded. In some locations, the flood waters were over 30 feet deep. In the heat and stagnation, the waters quickly became heavily polluted. Pump out operations began in early September 2005 to get the city dried out quickly. Lake Pontchartrain was the primary receiving water body. A variety of approaches ...

  • 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 ...

  • Water quality index as a tool for wetland restoration

    Worldwide, wetlands are subjected to increasing anthropogenic pressures resulting in loss of their hydrological and ecological functions. Such impacts are more pronounced in the case of wetlands in urban areas which are exposed to land use changes and increased economic activities. In many Indian cities, natural water bodies such as lakes are heavily polluted due to runoff from farmlands in ...

  • Monitoring watershed health

    Background Municipal water quality managers recognize the need for data that can be used to monitor and assess the impact of urbanization on the condition of natural watersheds. Storm events, in conjunction with the alteration of native landscape, building of roads and overuse of fertilizer, can contribute to excess nutrients, sediment and other pollutants in environmentally significant ...

  • Why are we monitoring nutrients at different depths?

    Recently, LG Sonic introduced the MPC-Lab, an innovative monitoring buoy that can monitor algae, physico-chemical variables, and even nutrients such as nitrogen and phosphorus in near real-time and at different depths in a body of water. Combined with our other monitoring tools, this system offers a unique way to detect the spatial and temporal patterns of nutrient concentrations which play a ...

  • Ultrasonic depth sensor to measure water levels

    The Dutch algae control company LG Sonic introduced an ultrasonic depth sensor to give the customers real-time insight in the water levels which allows them to adequately deal with water level fluctuations. Reservoirs used for industrial processes or the production of drinking water often deal with strong water level fluctuations. Due to events of high demand and evaporation, water levels in ...

  • Cyanobacteria successfully monitored and controlled by using ultrasound

    Cyanobacteria- also known as blue-green algae- cause problems when blooming in lakes, ponds and reservoirs. Mainly due to the production of toxins, cyanobacteria cause fish kill and the death of other aquatic animals. They also affect human beings, causing paralysis and skin irritation, and they are even thought to be related to the occurrence of liver cancer. In drinking water reservoirs, the ...

  • Map Algal Blooms with Satellite Remote Sensing Technology

    The quality of water bodies is a key determinant in the usability of the resource for the purpose required. It is therefore of great importance to managers of hydrologic resources to be able to confidently tell the status of their water resource. One of the major problems in the quality of surface water bodies is the blooming of algae and blue green algae. Algal blooms can result in ecological, ...

  • Monitoring, environmental emergencies management and water treatment improvement of freshwater lakes in China: the Chao Lake case study

    Severe eutrophication of freshwater lakes, with the subsequent risk of algal blooms, has a critical effect on the safety of drinking water supplies in China and is one of the main environmental emergencies in the country. This paper focuses on Chao Lake, a large, shallow eutrophic lake used as a source of drinking water. The study considers the possibilities of improving the lake monitoring ...

  • 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 ...

  • European bathing water quality in 2013

    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 jeopardize their health. The European Environment Agency (EEA) and the European Commission hope that this year's bathing water report ...

  • Strategies for Managing the Lakes of the Rotorua District, New Zealand

    The Rotorua district in New Zealand contains 12 nationally important lakes. Environment Bay of Plenty (EBOP), which has the responsibility of managing the quality of these lakes, set a routine monitoring program for these lakes and adopted the method of Burns et al. (1999, 2000) to analyse the data and calculate a numeric Trophic Level Index (TLI) value for each. In 1994, the district community ...
