  • Aeration and Mixing Bring Hussain Sagar Lake`s Ecosystem Back to Life

    Overview Hussain Sagar Lake in India faced an inflow of untreated waste and pollution causing decreasing DO levels and foul odors in the nearby community. An even more critical threat was eutrophication, or an excessive number of nutrients in the body of water, choking out the natural aquatic life. Given the lake is stagnate, circulation and the distribution of efficient aeration ...

  • Assessing the impacts of climate change on water resources in the Srepok watershed, Central Highland of Vietnam

  • The Power of 243 Vertical Wells

    This is a comparison of a Horizontal Remediation System and a Verticle Well System at a theoretical site with an area of 388,800 ft2   where with a Radius of Influence (ROI) of 20 feet, 12 Horizontal Remediation Wells, depending on plume geometry, can cover the same area as 243 vertical wells with the same ROI per well. Not only ...

  • Times are changing: Wastewater as a resource

    Times are definitely changing. It used to be that wastewater from whatever source – domestic, agricultural, industrial – was something to collect and pipe away as quickly and efficiently as possible. There was more water coming out of the ground or falling from the sky, so why bother investing time and money cleaning water that had already been used? Now, thanks to issues like ...

  • Overcoming water challenges through nature-based solutions

    Freshwater is a key resource and medium for various economic sectors and domestic purposes but its use is often at the expense of natural ecosystems. Water management must change to deal with urgent issues and protect aquatic ecosystems and their services, while addressing the demand for water from the competing claims for cities, agriculture, industry, energy and transport. In this paper key ...

  • Withdrawal of fresh water may reduce aquatic diversity

    Withdrawing fresh water from rivers and streams may adversely affect the health of fish and aquatic insects, according to a research team studying correlations between the two in North Carolina. The researchers, charged by the state of North Carolina and the state’s Department of Environmental Quality, investigated the relationship between changes in surface water flow and the diversity of ...

  • The best way to restore environments in the face of climate change

    Florida’s Kissimmee River once flowed freely. Fish, birds and other wildlife dwelled in the wetlands it fed. But in the 1960s, spurred by public outrage over flooding, the U.S. Army Corps of Engineers straightened the winding waterway and turned it into a drainage canal. Flip forward a few decades and the river is returning — at least in part. The U.S. Army Corps of Engineers has ...

  • Microbiological quality of ice and ice machines used in food establishments

    The ice used in the food industry has to be safe and the water used in ice production should have the quality of drinking water. The consumption of contaminated ice directly or indirectly may be a vehicle for transmission of pathogenic bacteria to humans producing outbreaks of gastrointestinal diseases. The objective of this study was to monitor the microbiological quality of ice, the water ...

  • Ecology of duckweed ponds used for nutrient recovery from wastewater

    The microorganism community that grows under duckweed shelter can play an important role on treatment processes. Therefore, the present study aimed to assess the zooplankton dynamic and microbial community in duckweed ponds (DPs) applied for domestic wastewater treatment under open field conditions. A pilot system comprised of two DPs in series (DP1 and DP2), with 10 m2 each, received domestic ...

  • USGS surveys, models high plains groundwater resources

    A United States Geological Survey publication and model of groundwater resources in the Northern High Plains aquifer can be used to better understand the region’s water resources, a critical component of scientific water management. This type of comprehensive study has not been made in more than 30 years The models can be used to assess the flow, quantity, sources, and sinks of groundwater ...

  • Removal of potentially toxic elements from aqueous solutions and industrial wastewater using activated carbon

    Water contamination with potentially toxic elements (PTEs) has become one of the key issues in recent years that threatens human health and ecological systems. The present study is aimed at removing PTEs like cadmium (Cd), chromium (Cr), copper (Cu) and lead (Pb) from aqueous solutions and industrial wastewater using activated carbon (AC) as an adsorbent through different batch and column ...

  • Input-output model based ecological risk assessment for ecological risk management of watersheds: a case study in the Taihu Lake watershed, China

    To achieve advanced watershed ecological management, policy-makers have struggled to predict ecological impacts for a long time. As a process of ecosystem analysis, ecological risk assessment (ERA) has been widely adopted to analyse the possibility of adverse ecological effects. ERA has developed from considering only a few indicators in an area to multiple sources and receptors in large-scope ...

  • Strategic management of water resources important to Ontario craft breweries

    The vast majority of craft breweries in Ontario understand the need to improve their water and resource management performance to save money, protect the environment and enhance community relations. This was a major finding of a survey of Ontario craft breweries conducted in the fall of 2016 that found 97 per cent of respondents agree that better water management is important or very important to ...

  • Ecologists pay disproportionately little attention to synthetic chemicals, study finds

    Manmade chemicals may alter ecological processes, yet few scientists are studying the role of these chemicals in global environmental change, say a group of researchers from the U.S. and Germany in a scientific paper published today in the journal Frontiers in Ecology and the Environment. In recent decades, humans have increased ...

  • Towards sustained sanitation services: a review of existing frameworks and an alternative framework combining ecological and sanitation life stage approaches

    Despite increased promotion, sanitation programmes have varying degrees of success partly because of limited consideration of the wider context beyond individual factors in programme design. Although a recent model, Integrated Behaviour Model for Water Sanitation and Hygiene (IBM-WASH) comprehensively addresses this gap, the model focuses on the initial adoption factors and lacks emphasis on ...

  • The Curious Divide between Conservation Science and IA

    Since returning to academia, I have been struck by a particular disjuncture between the biodiversity sciences and IA practice in my country, Namibia. Having worked across Africa, my suspicion is that it probably applies to the entire continent, perhaps even broader. Allow me to expand. I had my wildlife scientist hat on a few weeks ago at a southern African symposium on wildlife tracking and ...
