  • Considerations for the mitigation of nitrate contamination: stable isotopes and insights into the importance of soil processes

    Nutrient management is widely promoted to minimize the impact of intensive fertilizer use on groundwater quality, however watershed-scale stable isotope studies in eastern North America suggest nitrogen transport to groundwater is dominated by non-growing season fluxes derived principally from the mineralization and nitrification of soil organic matter. In the current field scale study, δ15N ...

  • Heavy metals in urban soils of Xuzhou (China), Part I: total concentration of heavy metals in soils

    Concentrations of Hg, As, Cd, Se, Sb, Zn, Cu, Ni, Pb, Ag, Sn, Cr, Sc, Ba, Li, Bi and V were measured in 21 topsoil samples collected from the city of Xuzhou (China). Lead, Zn, Cd, As, Hg, Sb, Cu, Sn, Ag, Se and Bi have been found to be enriched in the topsoils with respect to the background values of Xuzhou, while Sc, Ba, Li, V, Ni and Cr are nearly in the normal concentration range. These ...

  • Sample Handling Strategies for Accurate Lead-In-Soil Measurements in the Field and Laboratory

    ABSTRACT The inhomogenous lead-in-soil matrix can present serious obstacles to accurate sample collection and handling. In typical lead-in-soil measurement, particle size related errors in sampling and sample handling often exceed all other sources of error. The magnitude of error can vary widely depending on the particulate nature of the lead contaminant and the effectiveness of control ...

  • Soil physico-chemical changes following application of municipal solid waste leachates to grasslands

    AbstractConcerns about the use of residues from municipal solid waste incinerators (MSWI) in construction materials usually focus on the potential for heavy metals and organic chemicals to leach into drainage waters under the influence of rain. We hypothesised that high level of salts in the MSWI leachates may cause more of a problem, particularly on soil physico-chemical properties. Both bottom ...


  • Comparing Field Portable X-Ray Fluorescence (XRF) To Laboratory Analysis Of Heavy Metals In Soil

    ABSTRACT Field portable x-ray fluorescence (XRF) continues to gain acceptance as a complement to traditional laboratory testing of metal contaminated soil. The quality of data produced by field XRF varies with site conditions, soil composition, and sample preparation. Quality assurance protocols for the field method usually require that a number of field samples be split and sent to a ...

  • Recycling Waste Products from Molasses Fermentation: CSR Distilleries

    CSR’s Sarina ethanol distillery has changed from an environmental pariah in the local community into a welcome industry. Through a world-first plant design, it has reduced steam and water consumption, improved plant productivity and product quality, and turned a pollutant into a saleable, import-replacing product. Instead of closing down in the face of community opposition to its environmental ...


  • London 2012: Legacy or Liability?

    After spending hundreds of millions of tax payers’ money on a high profile ‘clean-up’, it has become clear that the 2012 Olympic Park actually remains classified as a contaminated brownfield site. Documents show that the whole area is to have as little as 2 feet (60cm) of “clean” material placed on top of a warning marker layer of orange plastic fabric sheeting, of a type called Terram 1000, ...

  • Conducting The Phase I Assessment - Records Review

     This is the second in a series of five articles relating to conducting Phase I Environmental Site assessments. Each article attempts to give the reader a thorough understanding of a specific aspect of the Phase I process and Clayton’s commitment to meeting or exceeding the requirements of ASTM Standard E 1527 Standard Practice for Environmental Site Assessments: Phase I Environmental Site ...


  • Enhanced Aerobic Bioremediation of Petroleum UST Releases in Puerto Rico.

    Abstract: Releases of petroleum compounds from underground storage tanks (USTs) containing diesel fuel and gasoline are a serious and increasingly prevalent problem in Puerto Rico. Remediation of groundwater impacted by these releases utilizing common methodologies can be quite costly and require long periods of time to implement. Oxygen is often the limiting factor retarding optimal ...

  • The New Environmental Insurance Products: When Does it Make Sense to Buy Them?

     Part One Introduction Real estate transactions with environmental problems often founder on attempts to shift the liabilities from one party to the other. In transactions with other types of problems, insurance is a popular risk transfer mechanism,  and is regularly used for that purpose, but it is used far less often when there are environmental risks. This so-called ...
