  • Sources of endocrine disrupting compounds in North Carolina waterways: A geographic information systems approach

    The presence of endocrine disrupting compounds (EDCs), particularly estrogenic compounds, in the environment has drawn public attention across the globe, yet we currently lack a clear understanding of the extent and distribution of estrogenic EDCs in surface waters and their relationship to potential sources. The objective of our study was to identify and examine the potential input of ...

  • Toxicity Identification Evaluation (TIE) as a Tool for Water Quality Management

    Whole effluent toxicity (WET) testing has evolved into a critical element of many National Pollutant Discharge Elimination System (NPDES) permits issued to both industrial and municipal dischargers. Over 6,500 dischargers to both fresh and salt waters are required to conduct toxicity tests to determine if their effluent might be potentially toxic to organisms in the receiving system. While ...

  • Improving Water Quality - A Review of the Mississippi River Basin Healthy Watersheds Initiative (MRBI) To Target U.S. Farm Conservation Funds

    This paper provides an assessment of the USDA’s Mississippi River Basin Healthy Watersheds Initiative (MRBI), a promising new approach to achieving cleaner water in agriculturally dominated watersheds in the United States. The initiative concentrates a portion of taxpayer-supported conservation funds in high-priority, targeted watersheds, which we found to be a better strategy than the ...

  • Erosion index derived from terrain attributes using logistic regression and neural networks

    Maps identifying areas prone to channel erosion within agricultural fields could be useful for conservation planners. The objective of this study was to test an approach for creating such maps with logistic regression and neural networks. Survey grade elevation measurements were obtained from on a Central Kentucky farm. The elevation measurements were used to create 4 by 4-m digital elevation ...

  • Piedroba Dewaters Slurry, Returns Clean Water to Holmes Beach Canals

    This project was a successful application of a total cleaning system (TCS), where the particular type of solids of the sediments permitted the dredger to avoid the costly construction of a dredged material maintenance area (DMMA), or the transportation and tipping fees for a municipal landfill. The surface waters were cleaned in tandem, and contributed to a higher quality benthic environment in ...

  • Environmental risk management: Leaving little to chance

    Life is risky at the best of times. And identifying and managing risks – in the environment, industry and financial markets – has become a priority for business and governments everywhere. Everyone knows what can go wrong. Environmental accidents, corporate scandals and financial imprudence have rung up damage bills in the billions of dollars. So the heat is on to find ways to better manage and ...

  • Who used your water yesterday?

    The answer to the question above boils down to numbers in the final analysis. With more than half of the world's population already based in urban areas the additional demand for core services such as water is overtaxing capacities for water supply and disposal in many of the world's larger cities. And the problem is only going to get worse. The proportion of the world's population that will be ...

  • Hazard material information management and regulatory compliance

    Prior to the 1970s, legislative acts addressing hazardous chemicals were few in number and specific to a handful of topics. The Refuse Act of 1899 was often ignored and rarely enforced, and the Atomic Energy Act of 1954 was exclusive to radioactive material. When it came to workplace and community safety involving the handling, storage, disposal, and transportation of hazardous materials, ...

  • Green Urban Infrastructure: Assessing Potential Ecosystem Services in Urban Cities

    Cities all over the world are currently experiencing climate change caused by rapidly increasing atmospheric greenhouse gases (GHGs). Fortunately, cities may mitigate GHG concentrations by incorporating vegetation into green urban infrastructure (GUI) to develop parks, green roofs, waterways, and other structures. For example, plants sequester carbon (C) by removing atmospheric ...
