  • Extensive Solutions for Removing Arsenic from Your Drinking Water

    You may not be aware that your water supply has unsafe levels of arsenic in it. If testing proves this to be the case, you must immediately find a form of arsenic water treatment to help you have access to clean drinking water again. Arsenic is a poisonous substance that has innumerable negative health effects on humans. There are several methods of performing arsenic removal from ...

  • Using Biological Filtration to Remove Arsenic from Drinking Water

    In 2001, the U.S. Environmental Protection Agency changed the standards for arsenic levels in drinking water. At that time, the agency had estimated that more than 36 million Americans were drinking water that contained arsenic levels at or above 3 parts per billion. A new standard was set, lowering the maximum contaminant level to 10 parts per billion (ppb) from the previous standard of 50 ppb. ...

  • Incorporating large-scale atmospheric variables in long-term seasonal rainfall forecasting using artificial neural networks: an application to the Ping Basin in Thailand

    Understanding long-term seasonal or annual or inter-annual rainfall variability and its relationship with large-scale atmospheric variables (LSAVs) is important for water resource planning and management. In this study, rainfall forecasting models using the artificial neural network technique were developed to forecast seasonal rainfall in May–June–July (MJJ), August–September–October (ASO), ...

  • Scarcity to solution: perceived reasons for safe drinking water scarcity and local coping responses in a coastal village of Bangladesh

    People are directly and indirectly exposed to changing weather patterns through changes in the quality of water, air, and food changes in ecosystems, agriculture, industry, human settlements and the economy. Hence, this study explored local perceived reasons for safe drinking water scarcity and under such circumstances the coping responses in their region. This is a descriptive study based on ...

  • OTEC in Paradise: The Philippines

    Paradise Legend has it that the Republic of the Philippines was born when the gods tossed 7,100 pearls into the ocean and islands popped up. Centrally located in Southeast Asia – just North of Australia and Indonesia, South of Japan and China, and East of Thailand and Singapore – the Philippines are considered by many to be the gateway to and from the Pacific. With ...

  • Water and your health fact sheet

    Water is a vital nutrient, essential to every single chemical process that occurs in our bodies. Water makes up two-thirds of the human body, and 75 percent of the human brain is water. Staying adequately hydrated allows our bodies to function as best they can, yet nearly 75 percent of Americans are chronically dehydrated without ever knowing it. Everyone understands the importance of drinking ...

  • What are the Top 10 Sustainability Technologies Crucial to Sustain Life on Earth

    Clean and green environment (CGE) technologies have taken center stage with rising water scarcity, energy depletion, and global warming threatening the Earth’s ability to nurture life. A concerted move toward sustainability, especially with regard to water-efficient technologies, is vital for future survival. Recent analysis from Frost & Sullivan,  ...

  • Comparative investigation of artificial neural network learning algorithms for modeling solar still production

    Three artificial neural network learning algorithms were utilized to forecast the productivity (MD) of a solar still operating in a hyper-arid environment. The learning algorithms were the Levenberg–Marquardt (LM), the conjugate gradient backpropagation with Fletcher–Reeves restarts, and the resilient backpropagation. The Julian day, ambient air temperature, relative humidity, wind speed, ...

  • The impact of atmospheric wet deposition on roof runoff quality in an urbanized area

    Understanding the sources of chemical components in roof runoff can help to prevent water quality problems in rooftop rainwater harvesting. To identify the contribution of wet deposition to the mass of components in roof runoff, the samples from air, rainwater, dust buildup and roof runoff were collected from an urban site in Shenzhen of China in 2011–2012. The results indicate that: (1) wet ...

  • Model predictions of toxaphene degradation in the atmosphere over North America

    Technical toxaphene (TT), a broad‐spectrum pesticide mixture, degrades in the environment, resulting in potential changes in toxicity. The present study uses a multi‐media model that we developed to estimate toxaphene degradation in the atmosphere over North America. The predicted degradation has strong spatial and temporal variability determined by processes such as emission and transport of ...
