  • Investigating and mapping spatial patterns of arsenic contamination in groundwater using regression analysis and spline interpolation technique

    The present study investigates the hypothesis that arsenic concentrations correlate with tubewell depth, and examines the effectiveness of spline interpolation, specifically completely regularized spline (CRS) and spline with tension (SWT) in estimating the magnitude of arsenic contamination in groundwater in Thanh Tri, a densely populated district located in the southern part of Hanoi City, ...

  • Integrated water resources assessment and management in a small watershed – a geomorphic approach

    Depleting water resources and increasing human demands on the available fresh water resources suggest the need and scope for integrated water resources assessment and management. Narava basin, a small watershed spread over 105 km2 with a khondalitic suite of rocks and gneisses of Archaean age in the north coastal region of Andhra Pradesh, India was studied to propose effective water resources ...

  • Data Requirements for Ground Water, Surface Water, and Leachate

    It is common for ground water to be contaminated with the water soluble substances found in overlying soils. Many of the required data elements are similar, e.g., pH, TOC, BOD, COD, oil and grease, contaminant identification and quantification, and soil and aquifer characterization. Additional water quality monitoring data elements include hardness, ammonia, total dissolved solids, and metals ...

  • Bioremediation of Nitrochlorobenzene, Nitroaniline, Chloroaniline, and Other Organics in Groundwater.

    ABSTRACT: The uppermost aquifer beneath a chemical plant contains residual concentrations of o-nitrochlorobenzene from a tank car spill, as well as other plant-related organic compounds of concern (COC), including 2-nitroaniline and o-chloroaniline. The aquifer consists of low permeability clays and silts, and produces only a few gallons of groundwater per day from a shallow ...

  • San Antonio’s Continuing Focus on Water Sustainability

    Endangered salamander provided unlikely impetus for conservation efforts Forty years ago, the citizens of San Antonio, Texas, used an average of 200 gallons of water per day per person, far over the national average. This drew the ire of surrounding cities due to the overuse of a shared aquifer. Today, water use has been cut to 117 gallons per person per day, and San Antonio has earned the ...

  • Falling water tables` knock-on effect on falling harvests

    Scores of countries are overpumping aquifers as they struggle to satisfy their growing water needs. The drilling of millions of irrigation wells has pushed water withdrawals beyond recharge rates, in effect leading to groundwater mining. The failure of governments to limit pumping to the sustainable yield of aquifers means that water tables are now falling in countries that contain more than half ...

  • Ethanol Production Plant Monitors Impacts to Water Supply and Stays in Compliance

    Application Under current ethanol plant configurations, water use for ethanol production ranges from 4.0 to 6.8 gallons of water required per gallon of ethanol produced. With the average new plant producing 120 million gallons of ethanol per year, water yields in excess of 1,000 gallons per minute are required; therefore adequate water supply is essential to the operation of an ethanol ...

  • Water resources management

    Managing regional or national water resources demands the integration of patterns and processes of both natural and social systems. This is essential to achieve the optimum interaction of man and nature since every aspect of water use and disposal impinges on ecosystems to a greater or lesser extent. Sustainability is the key issue: how can sustainable yields by abstraction from rivers, ...

  • Suitability of cotton as an alternative crop in the ogallala aquifer region

    Renewed interest in cotton (Gossypium hirsutum L.) production in the Ogallala Aquifer Region can be linked to development of early maturing varieties, rising energy costs, and declining water levels in the Ogallala Aquifer. The main objectives of this study were to assess the feasibility of growing cotton and estimate the cotton yield potential and the potential reduction in Ogallala Aquifer ...

  • What is an Aquifer?

    Aquifers are natural formations that store groundwater, but these vital structures are threatened The word “aquifer” means “water bearer.” In the context of hydrogeology, it refers to a natural underground formation of permeable ...

  • Innovative Technology to Implement a Reuse Water Program

    The city of Fort Myers has a population of approximately 58,000 and is located in Lee County, Florida. Over the last couple of years the city has experienced one of the highest growth rates in the country. The rapid increase in population in southwest Florida has stressed the available yield of the existing fresh water aquifers. Spurred by its involvement in the regional irrigation distribution ...

  • Accelerated Bioremediation as an Alternative to Conventional Remedial Technologies.

    ABSTRACT: Application of bioremediation as an alternative technology to expedite soil and ground-water remediation has been effective in reducing the concentration of hydrocarbons at an affordable cost. Bioremediation processes can be achieved by the addition of biological organisms into the soil and ground water which are contaminated and are microorganism deficient. The microorganism's ...
