  • Environmental Assessment Brownfield Study

    In late 2011, Global was contracted by the Genesee County Land Bank and City of Flint to prepare an Environmental Assessment (EA) in accordance with guidelines set for by the U.S. Department of Housing and Urban Development (HUD) 24 CFR Part 58 for the Smith Village Project. Global utilized the HUD recommended format during the preparation of the EA including completion of the Statutory Checklist ...

  • Beliefs, Politics, and Environmental Policy

    Introduction Many of us who work on environmental issues have faced the challenge of conveying their importance to nonspecialists. Perhaps we have found ourselves defending the robustness of climate science to a contrarian uncle, or extolling the importance of biodiversity to a dubious aunt. Our relations and friends are often educated people, skilled in their own professions, who have ...

  • Case study - TPH in produced sand for overboard discharge

    Customer uses TD-500D to measure TPH concentrations in produced sand on an offshore oil platform in Malaysia.  The sand contains high levels of crude oils and must be treated on-site prior to dumping it overboard.  The TD-500D was calibrated to Sitelab's TPH calibration kit, product CAL-056.  Methanol solvent was used to extract the samples.  For comparison, samples were also ...

  • Amino-functionalized mesoporous MCM-41: an efficient adsorbent for the removal of chromium (III) ions from aqueous solution

    Amino-functionalized mesoporous MCM-41 (NH2-MCM-41) has been synthesized and explored as sorbent for removal of trivalent chromium, from aqueous media. The chemical and morphological structures of NH2-MCM-41 were investigated by scanning electron microscopy, energy-dispersive x-ray, and x-ray diffraction techniques. The best performance of NH2-MCM-41 as sorbent for removal of ...

  • A simple approach to assess N load capacity of rice paddy fields in the southern Taihu Lake watershed

    High nitrogen (N) leaching from irrigated agricultural soils is the result of N input exceeding soil N load capacity (NLC). A simple approach was developed in this research to assess the NLC of paddy soils in the southern Taihu Lake watershed. Paddy soils were classified into four types (Submergenic, Illuvium, Gleyed, and Percogenic) and 28 soil samples representing all four types were ...

  • Polycyclic aromatic hydrocarbons (PAHs) in coastal sediments from urban and industrial areas of Asaluyeh Harbor, Iran: distribution, potential source and ecological risk assessment

    The distribution and toxicity levels of 16 EPA priority pollutant polycyclic aromatic hydrocarbons (PAHs) in the sediments of Asaluyeh shore, Iran were investigated. The total concentrations of the PAHs in surface sediments ranged from 1,054 to 17,448 ng/g dry weights with a mean concentration of 8,067 ng/g. The spatial distribution of PAHs showed that PAH levels are much higher in the ...

  • Eliminate Degassing When Measuring Viscosity of Compressor Oils

    Compressor oils can create unique challenges when trying to measure viscosity. Dissolved gases from refrigerants, in particular, tend to bubble out when these oils are measured using traditional viscometers. This can create errors in the measurement, typically causing readings to be much lower than they should be. One way to get around this problem is to allow the oil ...

  • VCU Testing for a Major Pipeline Company - Case Study

    Challenge Antea Group was contracted by a major pipeline company to complete a performance test of two marine VCUs and a VOC leak quantification of components during loading of marine vessels. The protocol for both of these tests had been developed by a previous consultant and TCEQ had not yet approved protocol. The client recently purchased the facility and had little information on ...

  • Ecological risk assessment of boreal sediments affected by metal mining: Metal geochemistry, seasonality, and comparison of several risk assessment methods

    The mining industry is a common source of environmental metal emissions, which cause long‐lasting effects in aquatic ecosystems. Metal risk assessment is challenging due to variations in metal distribution, speciation, and bioavailability. Therefore, seasonal effects must be better understood, especially in boreal regions in which seasonal changes are large. We sampled 4 Finnish lakes and ...

  • Electronic Chain of Custody (COC) in Environmental Data Management using the LSPECS upgrade for ESdat

    Summary As electronic information can be easily altered, a chain of custody ensures that the data presented is "as originally acquired" and has not been tampered with during the copying process or during analysis. When using ESdat Environmental Data Management System, all data is tracked and backed up electronically; there is no scope for transcription errors or loss of paper based ...

  • Case study - Low-flow groundwater sampling on a nuclear site

    Nuclear licensed site use of low-flow groundwater sampling shows: Reduced time, reduced quantity of purge water – both thus reducing cost - and reduced risk of operator contact especially with potentially radioactive-contaminated purge water thanks to a self-contained enclosed system. One of the biggest headaches on site is the purge water and the expense of getting rid of it – after ...
