  • Mississippi River an `Orphan` in Terms of Water Quality

    WASHINGTON, DC, October 18, 2007 (ENS) - The U.S. Environmental Protection Agency has failed to coordinate and oversee state water quality activities along the Mississippi River, leaving the nation's largest waterway an 'orphan,' the National Research Council says in a new report. Greater effort is needed to ensure that the river is monitored and evaluated as a single system, said the ...

  • Improving water quality in Europe`s rivers

    The European Water Framework Directive (WFD) urges policy implementation managers to respond to poor ecological, chemical and quantitative status of the water system caused by negative pressures from different drivers. This issue discusses recent experiences with regard to different stages of river basin management strategy, to help us understand how we can safeguard water, an indispensible ...

  • Project to improve water quality in River Thames

    Black & Veatch has been selected by Thames Water as principal contractor to upgrade and extend Mogden Sewage Treatment Works in West London. Construction will start in spring 2010 to significantly reduce the amount of storm sewage that overflows into the River Thames during heavy rainfall when the site becomes overloaded.

  • Louisiana addresses water quality in Tensas River

    The U.S. Environmental Protection Agency (EPA) awarded $130,402 to the Louisiana Department of Environmental Quality to improve water quality in the Tensas River, located in north-east area of the state. Specifically, the project will reduce nonpoint source pollutants by installing grassed filter strips that will filter sediment. The Clean Water Act (CWA) allows EPA the ability to help states and ...

  • U.S. EPA approves new water quality standards for Chicago River System

    The U.S. Environmental Protection Agency has approved the State of Illinois' new and revised water quality standards for five segments of the Chicago and Calumet Rivers. "In May of this year, US EPA notified the State of Illinois that upgraded water quality standards were necessary to protect the health and safety of the increasing number of people who use these rivers for recreation," said EPA ...

  • USDA Funds Conservation Projects for Water Quality Improvements in the Mississippi River Basin

    Agriculture Secretary Tom Vilsack today announced that the U.S. Department of Agriculture will fund existing conservation projects in 41 eligible watersheds in 12 states this fiscal year as part of its Mississippi River Basin Healthy Watersheds Initiative. The initiative supports USDA’s continuing efforts to help landowners and farmers protect and improve water quality in the Mississippi ...

  • River water quality in England and Wales improves for 18th consecutive year

    Data released by the Environment Agency shows that the quality of water in rivers in England and Wales continues to improve. Figures from the Environment Agency’s annual General Quality Assessment (GQA) show that 76 per cent of English rivers, and 95 per cent of those in Wales, achieved ‘very good’ or ‘good’ status in terms of chemical water quality in 2007, up from 55 and 86 per cent ...

  • EPA Takes Steps to Improve Water Quality of Illinois River

    Today, U.S. Environmental Protection Agency (EPA) is making available the Illinois River Watershed Modeling Program which resulted from several years of collaboration with local stakeholders, states and tribes in both Ark. and Okla. The Modeling Program will assist in the development of water pollution controls needed to meet water quality standards throughout the watershed and relies on two ...

  • Stormwater pollution tackled to improve water quality in Charles River, MA

    EPA is taking strong action to enact the next generation of environmental protection for the Charles River by tackling pollution problems caused by stormwater. Specifically, EPA today announced a targeted effort to apply more stringent controls on stormwater pollution in the Charles River watershed, where stormwater containing high levels of phosphorus is a chief culprit in dramatic algae blooms ...

  • River Water Quality indicator for sustainable development - 2008 results

    The river water quality indicator is one of the 68 indicators of the Government’s Sustainable Development Strategy. It separately measures biological and chemical river water quality on an annual basis and the indicator for each represents the proportion of river water, in terms of river length, which is considered to be of “good” quality. Headline results In England: 72 per cent of river ...

  • New water quality standards are necessary to protect the Mississippi River for recreation

    EPA has determined that new or revised water quality standards are necessary to protect the Mississippi River in Missouri. Missouri designated about 3,600 stream segments and all of its lakes for recreational uses in March 2006. However, Missouri did not assign the highest level of recreational use to a 195.5-mile segment of the Mississippi River that flows from St. Louis to the confluence of the ...

  • Putting a price on water quality

    One way to clean-up water pollution is to award 'credits' to facilities that reduce their emissions. These credits can then be traded with other facilities to compensate for pollution outputs. This controls overall pollutions levels, while creating an economic incentive to reduce emissions. Research using models that simulate water quality has been used to establish the value of these credits and ...

  • River Rhine commended for river basin management

    The River Rhine has won the first ever International River Foundation (IRF) European River Prize, which is given for remarkable achievements in integrated river basin management. The other finalists were the Órbigo River in Spain, the Upper Drau in Austria, and the Mura-Drava-Danube in Central Europe. River basin management of the Rhine has improved dramatically in recent years, ...

  • River quality in UK improving but still fail to meet EU standards

    Water quality in England and Wales has improved for the nineteenth year in a row the Environment Agency announced this week.  As a result, more rivers are becoming home for species that were once thought to be in terminal decline in them, such as salmon, eel and otters.  The improvement has been achieved mainly through investment by water companies, tougher action on polluters, ...

  • Optical water quality assessment

    Scientists at the U.S. Geological Survey (USGS) have proven that measuring fluorescence could improve source water monitoring during a study of the McKenzie River in Oregon.  The study was designed to assess the amount, type and source of dissolved organic carbon that exists in all sources of drinking water. Dissolved organic carbon can react with chlorine during water treatment and form ...

  • Water Quality System

    Let me explain that our basic idea is how better to use the not many typologies (and parameters) of on-line sensors available on market to make low-cost sustainable intelligent monitoring. We all know that the total water quality is related to about fifty of quality measurement analytic parameters, but on-site and in on-line way, it is possible to detect only about ten electro-chemical or ISE ...

  • Testing ecological toxicity in rivers

    Water quality in rivers is commonly classified according to its physical and chemical properties, but this may not fully describe its biological health. Polish researchers have tested a new method of water assessment, which looks at the toxicity to organisms of not just water, but also sediment and floodplain soil samples. This provides a more complete picture of a river's health and may help ...

  • River and drainage modelling seminars

    The River and Drainage Modelling Seminar Series MWH Soft co-presented in Malaysia have been successfully completed. The seminars were co-organised by Jabatan Pengairan Dan Saliran (JPS), the Malaysian Government's Department of Irrigation and Drainage and held in Kuala Lumpur and Penang on 1st and 2nd December. JPS are responsible for flood management and main river water quality throughout ...

  • US river flows altered by water management

    The amount of water flowing in streams and rivers has been significantly altered in nearly 90% of waters that were assessed in a new nationwide USGS study. Flow alterations are a primary contributor to degraded river ecosystems and loss of native species. Flows are altered by a variety of land- and water-management activities, including reservoirs, diversions, subsurface tile drains, groundwater ...
