  • How to investigate mercury in the oceans?

    Mercury is a highly toxic metal that affects the environment and can endanger people's health, as a powerful neurotoxin. The combustion of coal, waste and fuel are releasing hundreds of tons of heavy metal into the atmosphere annually, and its sediment enters to soil and water. Mercury measurements are part of the EU project "Global Mercury Observation System". The long-term goal of this ...

  • 10 Uses of Rainwater

    Collecting your own rainwater is an excellent way to conserve this precious resource. A basic rainwater collection system catches rainwater from your roof or other surface and channels it into a container for storage. Rainwater itself is generally clean, but it can pick up microorganisms, pollutants and debris when it hits your roof. This is why systems for rainwater use inside your home often ...

  • How listening to the ocean can help reveal environmental damage

    In 2013, Katherine Indeck listened to recordings of sounds made in a channel between the Gulf of Mexico and Tampa Bay, Florida. Some of the audio files had been collected in 2005 during an unusually severe red tide, a bloom of toxic algae that killed fish, dolphins and sea turtles. Other recordings were made after the ecosystem began to recover. During the recovery years, Indeck could hear sounds ...

  • Assessment of groundwater quality and health risk in drinking water basin using GIS

    Eğirdir Lake basin was selected as the study area because the lake is the second largest freshwater lake in Turkey and groundwater in the basin is used as drinking water. In the present study, 29 groundwater samples were collected and analyzed for physico-chemical parameters to determine the hydrochemical characteristics, groundwater quality, and human health risk in the study area. The ...

  • Real Time TOC Analysis in Steam and Condensate

    Executive Summary Steam in petro/chemical plants could be contaminated with hydrocarbons (TOC = Total Organic Carbons) from various sources. In any case this is a sign for defects in the process, whether it they occur in the heat exchanger, the blow down vessel, the condensate recovery or other parts of the system. Conventional solutions to monitor such contaminations use TOC- ...

  • Combating river pollution in China and India: policy measures and governance challenges

    Severe water pollution is among the top policy priorities in both China and India. This paper undertakes a comparative case analysis to examine efforts in combating river pollution in two major rivers – the Yangtze in China and the Ganga in India. Our analysis suggests that efforts in combating river pollution in the two Asian giants have encountered substantial challenges, such as the lack of ...

  • Polluters Extended Responsibility

    "Waste generation is my right but collection & disposal is a responsibility of others. I just throw the non-value items on the streets and outside the homes of my neighbors but the waste like newspapers, plastic items, fabrics, metals, furniture, e-waste etc. which can fetch value, I store in my house & work place and sale to scrap merchants at the best prices. I do not care for the ...

  • Widespread Plastic Pollution Found in Great Lakes Tributaries

    Tiny pieces of harmful plastic, called microplastics, are prevalent in many rivers that flow into the Great Lakes, according to a study published today in the journal Environmental Science & Technology. Results are also illustrated on a new USGS microplastics website. Microplastics ...

  • Superfund Investigates Land Pollution from the Past…and Present

    On September 7, 2016, we took steps to respond to states, tribes and citizens who asked for our help addressing contaminated sites. In response, we are adding 10 hazardous waste sites to the National Priorities List (NPL). The NPL is our list of more than 1,300 of the most contaminated sites in the country that we are addressing under the Superfund program. Superfund is one of the most important ...

  • Remediation of sewage and industrial effluent using bacterially assisted floating treatment wetlands vegetated with Typha domingensis

    This investigation reports the quantitative assessment of endophyte-assisted floating treatment wetlands (FTWs) for the remediation of sewage and industrial wastewater. Typha domingensis was used to vegetate FTWs that were subsequently inoculated with a consortium of pollutant-degrading and plant growth-promoting endophytic bacteria. T. domingensis, being an aquatic species, ...

  • Study offers first-ever map showing groundwater pollution of coastal areas of United States

    The study identified 12 percent of the continental U.S. coastline — including the northern Gulf Coast from Mississippi to the Florida Panhandle, northern Atlantic Coast, and Pacific Northwest — where the once-hidden drainage systems make the ocean most susceptible to freshwater contamination from septic tanks and fertilizer runoff. In contrast, another 9 ...

  • A real-time, rapid emergency control model for sudden water pollution accidents in long-distance water transfer projects

    A real-time, rapid emergency control (EC) model is proposed to cope with sudden water pollution accidents in long-distance water transfer projects. The EC model outputs the method of EC based on pollutant properties. A generalized form of EC model is proposed and tested with a demonstrative project. The rapid prediction formulas of emergency control parameters (ECPs) are proposed under ...
