  • New Spanish regulation on groundwater protection

    On 22 October it was issued Royal Decree 1514/2009 regulating the protection of groundwater against pollution and deterioration. The legal framework of this Royal Decree is formed by Directive 2000/60/EC (WFD) in particular Article 17, and Directive 20006/118/EC. The main objectives are to prevent or limit groundwater pollution and to establish criteria and procedures to assess their chemical ...

  • Brackish Water as a Resource

    There’s a great deal of talk and debate about the value of treating brackish water, or water that is more saline than fresh water, but not quite as saline as seawater. Brackish water can result from the mixing of seawater with fresh water, as in surface waters such as estuaries or other watery ecosystems, or it can occur underground in aquifers. Salinity Levels Although ...

  • Train derailment prompts contaminated land investigation

    On March 30th 2015 a long freight train, transporting a variety of goods including lumber and chemicals, wound its way through the state of Mississippi. At around 5pm, part of the train failed to negotiate a curved portion of the track in a rural area near Minter City, resulting in the derailment of nine railcars, one of which leaked chemicals onto agricultural farmland and woodlands. Emergency ...

  • US groundwater protection regulations `not comprehensive enough`

    Groundwater protection is the responsibility of everyone including the chemical industry. An energetic group of state and federal groundwater agencies, industry, environmentalists and other stakeholders, however, has made it a key area of their focus. The Ground Water Protection Council (GWPC) is a nonprofit Section 501(c)(6) organization dedicated to promoting and ensuring the use of best ...

  • Wastewater and groundwater

    Nearly 25 percent of the population in the United States—in more than 25 million homes—disposes of wastewater through onsite, or unsewered, systems that return treated effluent to the ground. This is an important public health issue because many of those same homes use wells that rely on groundwater for the drinking water supply. With ...

  • Geoenvironmental properties of the groundwater protective soil layers in Brass, Nigeria

    The aim of this paper is to determine the geoenvironmental properties of the groundwater protective soil layers in Brass Island, the Niger delta region of Nigeria. Six borings were sampled in accordance with BS 1377:1975. The soils through which the borings were made consisted of inorganic clays, sandy–clay and sandy–silt mixtures. Permeability, transmissivity, leakage coefficient and formation ...

  • An integrated Approach to Groundwater Protection Using Modelling and GIS, Groundwater in a Watershed Context (PDF)

    A pilot study for delineating wellhead protection areas was undertaken in Cacapava, Brazil, which integrated three-dimensional capture zone modelling with available groundwater and contaminant-source databases, using a four-step process. A contaminant source inventory was developed and each source was ranked based on its potential impact. Next, the thickness of the unsaturated zone and the ...


  • Environmental protection

    An analysis of the lighting industry shows a significant shift from the use of incandescent bulbs to fluorescent bulbs. Incandescent bulbs use more fossil fuel energy, cost more and are less effective than fluorescent bulbs, which produce more lumens. Usage of fluorescent bulbs, however, is not entirely without risk because they contain mercury, a chemical compound that can have debilitating ...


  • Towards an effective protection of groundwater resources: putting policy into practice with the drinking water protection file

    Groundwater in the Netherlands is a major resource for drinking water. As such it must be carefully monitored and managed. Evaluation of the European Water Framework Directive (EU-WFD) showed that protection of this valuable resource needs improvement. The Drinking Water Protection File identifies necessary measures needed per water abstraction site. The Protection File is part of the Dutch ...

  • Who Owns Groundwater?

    California’s drought underscores the need to improve how the state - and the rest of us - divvy up a resource in demand. Grapevines march across wires strung along rolling hills, their little trunks improbably supporting heavy black fruit. Cindy Steinbeck’s family has been farming this land since 1920. They grow Zinfandel, Viognier, Cabernet, Merlot, and Petite Syrah grapes but are ...

  • Management and protection of groundwater resources in semi–arid zones: application of hydrochemical methodologies to Essaouira Synclinal Basin, Morocco

    The water resources of the Essaouira basin are characteristic of a semi–arid climate. It is a coastal aquifer located on the Atlantic coastline, corresponding to a sedimentary basin with an area of about 200 km². The geological structures delineate a syncline bordered by the Tidzi diapir of Triassic age which outcrops to the E and S. In the Essaouira basin, a multi–aquifer composed of detrital ...

  • Contamination of groundwater and the risk to human health

    Groundwater is a major source of drinking water in many parts of the world. In industrialised countries, there is increasing concern that groundwater reserves are being contaminated by industrial effluents and the chemical pesticides and fertilizers used in intensive farming. This paper compares some of the existing guidelines for acceptable concentrations of certain common contaminants in ...

  • Fighting saltwater intrusion into groundwater supplies

    As freshwater supplies around the world diminish, human intervention is needed to protect existing sources to slow the onset of water scarcity. One ongoing struggle is to preserve the water in underground aquifers, which cities often rely on for drinking water. Intrusion of saltwater into these underground supplies is rendering them unfit for consumption or irrigation. The rock and soil that ...

  • Why it’s time to elevate groundwater

    Groundwater stored in the earth’s crust underpins all our lives – the ultimate source of freshwater for billions has become victim of over-extraction and the ultimate sink for pollutants.   For too long, not enough has been done to regulate the use of this precious, on-demand resource and manage disposal of waste. If rates of groundwater depletion have tripled in the past 3 ...
