  • Salinity monitoring in western Australia using remotely sensed and other spatial data

    Received for publication January 27, 2009. The southwest of Western Australia is affected by dryland salinity that results in the loss of previously productive agricultural land, damage to buildings, roads, and other infrastructure, decline in pockets of remnant vegetation and biodiversity, and reduction in water quality. Accurate information on the location and rate of change of the extent of ...

  • Furrow seeding with plastic mulching increases stand establishment and lint yield of cotton in a saline field

    Uniform stand establishment is essential for profitable cotton (Gossypium hirsutum L.) production in saline fields. This study was conducted during 2003 and 2004 to determine if furrow-bed seeding and plastic mulching improve stand establishment and cotton lint yield in a saline field. The experiment was arranged in a split-plot design with seeding patterns (flat-seeded and furrow-seeded) as main ...

  • Validation of an extraction method for Cry1Ab protein from soil

    Corn expressing insecticidal proteins derived from Bacillus thuringiensis (Bt corn) has increased in usage in the United States from 8% of total corn acreage in 1996 to 67% in 2012. Due to this increase, it is important to be able to monitor the fate and transport of the insecticidal Bt proteins to evaluate environmental exposure and effects. Accurate and validated methods are needed to ...

  • Stevens Hydra Probe Soil Sensors Deployed in Florida Swamp for Restoration Study

    Coastal wetlands provide a large number of critical functions that benefit the surrounding ecosystems and the neighboring human population centers. Coastal flood plains and wetlands help prevent the flooding and destruction of coastal communities by storm surges, acting as a natural buffer to protect communities near the coast. The bald cypress (Taxodium distichum) is one of the dominant tree ...

  • Groundwater monitoring and assessment with ESdat environmental data management software and its use in groundwater remediation plans

    Groundwater investigations, contaminated/industrial sites, landfill and regulatory compliance are all ideal areas for environmental consultants and site managers, specializing in groundwater monitoring and assessment, to use environmental data management software. A successful groundwater ...

  • The effect of pipe collectors in reducing the drainage coefficient rate

    A high groundwater table and soil salinity, especially in arid regions, often cause serious problems for agriculture. In irrigated areas the subsurface drainage can be an effective technique to lower the depth of the groundwater table and reduce soil salinity. In drainage systems, lateral pipes are designed to collect the free water from soil and convey it into collectors. In other words, ...

  • Time-lapse resistivity investigations for imaging saltwater transport in glaciofluvial deposits

    Abstract  Five intersecting resistivity sections have been measured in glaciofluvial deposits hosting an aquifer of regional importance situated along a heavy traffic highway in Sweden. The winter salt spreading has caused a regular salinity increase through the years. For imaging the transport of saltwater in the aquifer, the sections were measured exactly in the same location before and ...


  • Water quality for irrigation and drinking water use of Aflaj in Oman

    The Sultanate of Oman is an arid country with scarce water resources mainly consisting of groundwater. Aflaj are artificial canals constructed centuries ago to transfer horizontally the groundwater to a location at the surface. The water quality of these Aflaj is a very important factor to be considered for healthy and safe use of this water. This paper aimed to study the characteristics of the ...

  • Field application of a planted fixed bed reactor (PFR) for support media and rhizosphere investigation using undisturbed samples from full-scale constructed wetlands

    This study presents a novel method for investigations on undisturbed samples from full-scale horizontal subsurface-flow constructed wetlands (HSSFCW). The planted fixed bed reactor (PFR), developed at the Helmholtz Center for Environmental Research (UFZ), is a universal test unit for planted soil filters that reproduces the operational conditions of a constructed wetland (CW) system in ...

  • Toxicological and Environmental Safety Data - Case Study

    Introduction AGRAGEL is a cross-linked copolymer of acrylic acid and acrylamide partially neutralized as potassium/ ammonium salt. The polymer is in its dry form a granulate and forms a gel-like material upon addition of water or aqueous solutions. Due to the cross-linking it is insoluble in water. Uptake of water is facilitated mainly by the negative carboxylic groups of the polymer and ...

  • Closures of mine a new challenge for Romania

    AbstractThe mining activity is one of the oldest activity in Romania, dating from the year 100 B.C. The gold and silver ores represented one of the riches of our country. In time the economic content of metals diminuend, and the ore mines become non profitable. Due to this situation the best option of the State was the closure and ecological rehabilitation of the mines.The steps for the ...


  • Processing Wastewater through Reed Beds: BHP Steel Long Products Division

     In the semi-arid region surrounding Whyalla in South Australia, BHP is creating an artificial wetland that promises to make its effluent cleaner than its input water. The wetland is projected to cost around 40% of a conventional treatment works, with significantly less operating costs. The project will conserve one of the most precious resources in the world’s driest country - water - and ...


  • Correlations of Vibrio fischeri Bacteria Test Data with Bioassay Data for Other Organisms

    AbstractLinear relationships of the median lethal concentrations of several hundreds of chemicals for a variety of organisms with Vibrio fischeri median effective concentrations are investigated. Significant correlations can be developed for many aquatic species including the fishes fathead minnow, bluegill, catfish, goldfish, goldorfe, guppy, killifish, rainbow trout, sheepshead minnow, and ...

  • Biodegradation of MTBE Utilizing A Magnesium Peroxide Compound: A Case Study.

    ABSTRACT: A patented magnesium peroxide compound was recently employed at an underground storage tank facility to increase the available oxygen in the groundwater for the biodegradation of fuel hydrocarbons. The objective of this remedial effort was to substantially reduce the dissolved-phase concentrations of BTEX and MTBE and to arrest further migration of the dissolved fuel hydrocarbon plume. ...

  • Spolchemie site remediation and NanoRem field site application

    Site Remediation The Spolchemie site was chosen as one of the NanoRem case study sites, to test two types of nanoparticles (NPs) (zerovalent iron - nZVI and iron oxide NPs) for in situ remediation of BTEX (Benzene, Toluene, Ethylbenzene, and Xylenes) contamination. Nanoremediation was seen as an opportunity to enhance the in situ biodegradation of the BTEX contaminants and to reduce the ...

  • Recycled Water saves California Farms

    After studies show no viable microorganisms in tertiary treated wastewater, growers in Salinas Valley now get two-thirds of their agricultural water needs from recycled sources. RECYCLED water is saving the farm for approximately 75 growers in the Salinas Valley along California’s Central Coast. Because their wells were becoming contaminated with seawater, these growers began irrigating their ...
