  • Act before there’s not a drop to drink

    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 ...

  • 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 ...

  • 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 ...

  • Artificial lake in Swanscombe, Kent Project - Case Study

    A former quarry for cement production is being transformed into a residential area, with 6250 homes, various shops and parks, and an enormous lake. That, in a nutshell, is the megaproject that Trisoplast played a crucial role in 2009. We lined the bottom of the nearly 18-hectares-large lake with Trisoplast to ensure there would be absolutely no risk of groundwater contamination. Exceptional ...

  • Assessing environmental risks of laundry detergents in greywater used for irrigation

    The objective of this study was to assess the environmental risk posed to Australian and New Zealand ecosystems by the presence of powdered laundry detergents in greywater used for irrigating gardens. Fifty powdered laundry detergents were assessed and all contained hazards which posed moderate to very high risks from increased alkalinity, sodicity and salinity to plants and soils when used at ...

  • Clean Water Act

    The Clean Water Act (CWA) is the primary federal law in the United States governing water pollution. Passed in 1972, the act established the goals of eliminating releases of high amounts of toxic substances into water, eliminating additional water pollution by 1985, and ensuring that surface waters would meet standards necessary for human sports and recreation by 1983. The principal body of law ...

  • Prairie and Turfgrass buffer strips modify water infiltration and leachate resulting from impervious surface runoff

    Concerns over NO3–N concentrations in drinking water and potential subsurface transport of P to surface waters are driving legislation on precautionary N and P application restrictions on turfgrass areas and in recommendations for vegetative plantings within urban environments. Two plant communities and three impervious:pervious surface ratios were examined for effects on leachate water quantity ...

  • Factors affecting the performance and risks to human health of on-site wastewater treatment systems

    Aerobic wastewater treatment systems (aerobic systems) are the preferred choice in a region overlying a karstic aquifer used for drinking water supplies, as they are thought to provide better protection to groundwater and human health than standard septic systems. However, aerobic systems in operation do not always perform to design standard; while this is often blamed on lack of maintenance, few ...

  • Conversion to Extensive Grass Land for Flood Risk Management

    The Mitigation Strategy of the measure Conversion to Extensive Grassland refers to flood prevention and environmental protection also. Flood protection can be achieved by: Increase the infiltration of rainwater by high roughness and preventing soil silting, Reducing the flow velocity of surface run off, The hydrologic-hydraulic effect varies depending on the ...

  • Preliminary analysis of phosphorus flow in Hue Citadel

    Characteristics of waste and wastewater management can affect material flows. Our research investigates the management of waste and wastewater in urban areas of developing countries and its effects on phosphorus flow based on a case study in Hue Citadel, Hue, Vietnam. One hundred households were interviewed to gain insight into domestic waste and wastewater management together with secondary ...

  • Semi-analytical 3D solution for assessing radial collector well pumping impacts on groundwater–surface water interaction

    We present a new semi-analytical flow and transport model for the simulation of 3D steady-state flow and particle movement between groundwater, a surface water body and a radial collector well in geometrically complex unconfined aquifers. This precise and grid-free Series Solution-analytic element method approach handles the irregular configurations of radial wells more efficiently than ...

  • Field scale longitudinal dispersivities estimation in a karstic aquifer

    To simulate contaminant advective transport it is required to provide dispersivity values to the models, values that are unknown in many cases. In this paper a methodology is presented to estimate longitudinal dispersivities at field scale, based on the monitoring of groundwater quality at an unconfined aquifer that is below a waste disposal site with no liners for groundwater protection, and by ...

  • Road Over Sensitive Groundwater Areas - Case Study

    When constructing or extending new roads, the responsible designers and contractors are increasingly faced with the task of preventing soil contamination. Therefore, measures for the protection of the groundwater are necessary in more and more cases. The corresponding requirements and specifications for such measurements are regulated in the "guide-line for constructional measurements of roads in ...

  • A new frontier in Texas: managing and regulating brackish groundwater

    The challenge of providing access to clean water is visible in Texas, where chronic drought coincides with increasing water demand. The 2012 Texas State Water Plan reports a 2,700 million cubic metres (MCM) gap between freshwater supply and demand in 2010, a number predicted to grow to 3,100 MCM by 2060. Due to the difficulty of reducing water demand, policy makers and water providers are ...

  • Environmental infrastructure and socio-economic indicators in San Pedro Sula, Honduras

    Access to water and sanitation was evaluated with respect to socio-economic factors for San Pedro Sula, Honduras (SPS), a medium-sized industrial city. A multidisciplinary analysis was conducted using socio-economic distribution and infrastructure assessments to determine the nature and extent of any existing inequalities. Although piped water access was nearly universal, socio-economic status ...

  • 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 ...
