Synopsis Evaluation of Selected DNA-based Technology in Impaired Watersheds Impacted by Fecal Contamination from Diverse Sources by : Marirosa Molina
Fecal pollution of surface waters is a top reason for impairment, as reported in the U.S. Environmental Protection Agency's report on the quality of the Nations waters. To be able to develop and implement TMDLs for impaired aquatic resources, it is imperative to determine the sources of the contamination. One tool used to determine the sources of bacterial fecal contamination is to apply a microbial source tracking approach to the system of interest. Microbial source tracking (MST) approaches are based on the assumption that specific strains of bacteria, genetic fingerprints, or DNA-based markers are associated with specific host species. Because accurate source identification of fecal contamination is essential in MST, more sensitive, selective and reliable molecular markers are required. The two types of genotypic methods that have been applied widely in a variety of environments can be classified as library-independent (LI) and library-dependent (LD). For both types, the temporal and spatial stability of selected genotypes are aspects that need to be evaluated, and these aspects are often times missing when applying MST to environmental samples. LD-MST methods require the development of large databases comprised of source-specific isolates. Once a source-specific fingerprint has been identified, the temporal and spatial variability of that particular genotype still needs to be validated. LI-MST is based on the application of culture-independent methods such as amplification of DNA from environmental samples using 16S rDNA markers in combination with polymerase chain reaction (PCR).

Synopsis Environmental Microbiology by : Ian Pepper
Designed for advanced undergraduate students, graduate students, and environmental professionals, this book builds upon the tremendous success of the previous editions with a comprehensive and up-to-date discussion of environmental microbiology as a discipline that has greatly expanded in scope and interest over the past several decades. From terrestrial and aquatic ecosystems to urban and indoor environments, this edition relates environmental microbiology to a variety of life science, ecology, and environmental science topics including biogeochemical cycling, bioremediation, environmental transmission of pathogens, microbial risk assessment, and drinking water treatment and reuse. The final chapter highlights several emerging issues including microbial remediation of marine oil spills, microbial contributions to global warming, impact of climate change on microbial infectious disease, and the development of antibiotic-resistant bacteria. - Presents state-of-the-art research results with key, recent references to document information - Emphasizes critical information using "Information Boxes" throughout - Includes real-world case studies to illustrate concepts, along with frequent use of graphics, cartoons and photographs - Offers questions at the end of each chapter designed to test key concepts - Lecture slides available for instructors online

Synopsis Strengthening Forensic Science in the United States by : National Research Council
Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.

Synopsis Indicators for Waterborne Pathogens by : National Research Council
Recent and forecasted advances in microbiology, molecular biology, and analytical chemistry have made it timely to reassess the current paradigm of relying predominantly or exclusively on traditional bacterial indicators for all types of waterborne pathogens. Nonetheless, indicator approaches will still be required for the foreseeable future because it is not practical or feasible to monitor for the complete spectrum of microorganisms that may occur in water, and many known pathogens are difficult to detect directly and reliably in water samples. This comprehensive report recommends the development and use of a "tool box" approach by the U.S Environmental Protection Agency and others for assessing microbial water quality in which available indicator organisms (and/or pathogens in some cases) and detection method(s) are matched to the requirements of a particular application. The report further recommends the use of a phased, three-level monitoring framework to support the selection of indicators and indicator approaches.Â

Synopsis Regional Cooperation for Water Quality Improvement in Southwestern Pennsylvania by : National Research Council
The city of Pittsburgh and surrounding area of southwestern Pennsylvania face complex water quality problems, due in large part to aging wastewater infrastructures that cannot handle sewer overflows and stormwater runoff, especially during wet weather. Other problems such as acid mine drainage are a legacy of the region's past coal mining, heavy industry, and manufacturing economy. Currently, water planning and management in southwestern Pennsylvania is highly fragmented; federal and state governments, 11 counties, hundreds of municipalities, and other entities all play roles, but with little coordination or cooperation. The report finds that a comprehensive, watershed-based approach is needed to effectively meet water quality standards throughout the region in the most cost-effective manner. The report outlines both technical and institutional alternatives to consider in the development and implementation of such an approach.
