toxic algal bloom monitoring Articles

  • Algal bloom causes and prevention

    Algal blooms are also known as marine blooms or water blooms, and are actually a sudden increase in the population of algae in water scenery. Algal blooms usually take place in freshwater, such as lakes and water reservoirs as well as in marine milieus. They can be easily identified by coloration of the water ensuing from the high density of pigmented cells. Though many types of algae can form ...

  • Impacts of Climate Change on the Occurrence of Harmful Algal Blooms

    Climate change has been occurring naturally as well as caused by anthropogenic activities over the decades. In relation to the fresh and marine water, the concentration of greenhouse gases results in temperature rise of surface water, lower pH and changes to precipitation, evaporation and vertical mixing of water. All these consequences of changing the environment in combination with excessive ...

  • 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 ...

  • Economic impact of algae blooms

    How much does an algae bloom cost? What is the price of inaction? Algae and cyanobacteria blooms are issues of considerable concern for environmental agencies, drinking water companies, municipalities and people alike. The incidence of Harmful Algae Blooms (HAB), along with its adverse effects, have been increasing in recent years as a result of climate change, increased fertilizer runoffs into ...

  • LG Sound integrates new technology to detect toxic algae blooms

    LG Sound introduces satellite remote sensing technology in order to detect toxic algae blooms. Satellite remote sensing allows for detection of water quality from a distance with information obtained from satellites. Together with several European universities we discovered that different types of algae require different types of ultrasonic treatment. Therefore, it is important to detect ...

  • 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 ...

  • 3 Common Water Quality Concerns

    About 10 percent of pond owners experience water quality problems in their ponds. Unfortunately, most pond owners pay little attention to managing the quality of water and never get it tested. As a result, the problem is detected only when it gets worst. Water quality is influenced by both natural processes and external environmental factors.Natural factors may include the types of rock and soil ...

  • EPA assessing wastewater nutrient pollution

    Nutrient pollution of waterways is the “single greatest challenge to our nation’s water quality,” according to the United States Environmental Protection Agency. Across the U.S., excess nitrogen and phosphorus are entering waterways, presenting seemingly constant challenges. To address these challenges, the EPA is surveying the nation’s publicly owned wastewater treatment ...

  • Can incentives protect Canada’s clean water?

    Clean water is a vital, valuable resource for Canada. We drink it. We grow food with it. We generate power using it. We use it as an input to industry, from manufacturing to oil and gas production. We swim, splash, and paddle our canoes in it. And clean water isn’t valuable just to humans; it also underpins essential ecosystems all over the country. But do our policies reflect the ...

  • 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 ...

  • Optimizing Wastewater Treatment

    ' Growing volumes of both industrial and municipal wastewater are being discharged to surface waters but the treatment provided frequently is inadequate to protect the desired uses of the receiving waters. With limited resources in terms of both institutional capacity and finance, governments face difficult choices in optimizing their investments in municipal systems and establishing practical ...
