  • Critical Evaluation of Waterbody Assessment Processes

    The states’ ability to confidently determine compliance of ambient conditions with water quality standards is limited by the availability of data and selection of appropriate assessment methodologies, resulting in greater likelihood of misinterpretation of the status of our nation’s waters. The objective of this research was to critically evaluate the methodologies states employ when assessing ...

  • Metropolitana milanese reduces water loss on critical steel pipeline

    Assessing the condition of buried water infrastructure can yield a variety of outcomes that are difficult to predict. Sometimes, they even seem random. The common belief that the age of a pipe determines its condition is rarely correct – in many cases, a newer main can be in worse condition than one twice or three times as old. Instead, operational, environmental and installation factors ...

  • Transforming Large Databases into Critical Knowledge Using Data Mining - Three Case Studies in South Carolina and Georgia

    ABSTRACTData mining is an emerging field that addresses the issue of converting large databases into knowledge. Data mining methods come from different technical fields such as signal processing, statistics, and artificial intelligence. Data mining employs methods for maximizing the information content of data, determining which variables have the strongest relationships to problems of interest, ...

  • An approach for determining the most critical among a suite of chemical contaminants at a drinking water intake

    An integrated approach for the identification and assessment of the most critical chemical contaminant(s) at a drinking water intake has been developed. It involves the determination of a threshold or critical raw water concentration (CRWC) for target contaminants using the observed overall removal efficiency of a specific water treatment plant (WTP) and regulated drinking water concentrations ...

  • Development of a GIS method to localize critical source areas of diffuse nitrate pollution

    The present study aimed at developing a universal method for the localization of critical source areas (CSAs) of diffuse nitrate (NO3−) pollution in rural catchments with low data availability. Based on existing methods, land use, soil, slope, riparian buffer strips and distance to surface waters were identified ...

  • Effectiveness of a Sediment Time Critical Removal Action – PCB Reduction in Fish Tissue, Surface Water and Sediment via Wet Excavation

    Documenting successful remediation of polychlorinated biphenyl (PCB)‐contaminated sediments is limited; potentially due to inadequate monitoring methods, complexities associated with the environment, and selected remedial techniques. At some sites, absence of appropriate baseline and post‐removal monitoring limits proper evaluation of remedial efficacy. Accurate interpretation of interactions ...

  • Toxic concentrations in fish early life stages peak at a critical moment

    During the development of an embryo into a juvenile, the physiology and behavior of a fish change greatly, affecting exposure to and uptake of environmental pollutants. Based on experimental data with sole (Solea solea), an existing bioaccumulation model was adapted and validated to calculate the development of concentrations of persistent organic pollutants in the tissue of developing fish. ...

  • Accumulated state of the Yukon River watershed: Part I critical review of literature

    A consistent methodology for assessing the accumulating effects of natural and man‐made change on riverine systems has not been developed for a whole host of reasons including a lack of data, disagreement over core elements to consider, and complexity. Accumulated State Assessments of aquatic systems is an integral component of watershed cumulative effects assessment. The Yukon River is the ...

  • City of tarpon springs assesses critical ductile iron force main

    Across the United States, there are many thousands of water and wastewater utilities that serve populations less than 50,000. Although the majority of attention surrounding aging infrastructure focuses on the challenges of large utilities, these small utilities are often faced with greater challenges. Smaller utilities often have fewer resources – both financial and personnel – ...
