Download or read book Galena Sinsinawa Rivers Watershed TMDL Report written by and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "The U.S. Environmental Protection Agency has conducted a complete review of the final Total Maximum Daily Loads (TMDL) for segments within the Galena/Sinsinawa Rivers watershed (GSRW), including support documentation and follow up information. The GSRW is in northwestern Illinois in Jo Daviess County. The GSRW TMDLs address impaired primary contact recreation due to excessive bacteria, impaired aquatic life use due to excessive zinc and impaired aquatic life and aesthetic quality due to excessive nutrients (phosphorus)"--approval letter.

Book Utility of Watershed Models

Download or read book Utility of Watershed Models written by Robert Nunoo and published by . This book was released on 2020 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: Watershed models are used to represent the physical, chemical, and biological mechanisms that determine the fate and transport of pollutants in waterbodies (Daniel 2011). These models, in general, are used for exploratory, planning, and regulatory purposes (Harmel and others 2014). Watershed models have numerous applications; one such use is the development of total maximum daily load (TMDL). TMDL is the amount of pollution a waterbody can receive without becoming impaired. Because of the challenge of uncertainty associated with models and the TMDL development process, the United States Clean Water Act Section 303 (d)(1)(c) requires that a margin of safety (MOS) be specified to account for uncertainty in TMDLs. The question of how MOS is estimated in TMDL was identified as a problem by the National Research Council (NRC 2001). Since the identification of the problem about two decades ago, there have been very few inventories or audits of approved TMDL studies.This study describes a natural language processing and machine learning aided review of the MOS in approved TMDLs from 2002 to 2016. The study determined whether the MOS values incorporated followed a pattern and examined whether there exist a relationship between MOS values and some ecological conditions. Relatively few TMDLs were based on some form of calculation to estimate explicit MOS values; these TMDLs constituted only 16% of the reviewed sample. The remaining 84% used conventional values, but few of those studies provided reasons for their selected values. A statistical assessment of those MOS values revealed that the MOS depended on States (location of waterbody), USEPA regions, waterbody type, designated water use, TMDL model used, and dataavailability. The findings indicate that few TMDL developers are following the National Research Council’s suggestions of using a rigorous uncertainty estimation approach for rational choices for the MOS. An adaptive approach based on Bayes-Discrepancy was proposed for estimating an MOS for a TMDL. The approach is based on the Bayesian hierarchical framework of estimating uncertainty associated with watershed models. With this approach, TMDL developers can communicate the effects of their watershed model. The approach was applied to a Ferson Creek model of the Fox River watershed to access variability and uncertainty in the model results, and also estimate possible MOS values for two monitoring stations in the watershed. Results suggest that an MOS of 0.04 mg/L could lead to a 0.1 probability of violating the water quality standard for an underpredicting model. The Bayes-discrepancy estimation method will enable TMDL developers and watershed managers to strike a balance between implementation options and water quality concerns.

Book Great American Judges 2 volumes

Download or read book Great American Judges 2 volumes written by John R. Vile and published by Bloomsbury Publishing USA. This book was released on 2003-06-23 with total page 1031 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inspiring and instructive biographies of the 100 most influential judges from state and federal courts in one easy-to-access volume. Great American Judges profiles 100 outstanding judges and justices in a full sweep of U.S. history. Chosen by lawyers, historians, and political scientists, these men and women laid the foundation of U.S. law. A complement to Great American Lawyers, together these two volumes create a complete picture of our nation's top legal minds from colonial times to today. Following an introduction on the role of judges in American history are A–Z biographical entries portraying this diverse group from extraordinarily different backgrounds. Students and history enthusiasts will appreciate the accomplishments of these role models and the connections between their inspiring lives and their far-reaching legal decisions. William Rehnquist, Oliver Wendell Holmes, Jr., and 12 other Supreme Court justices are found alongside federal judges like Skelly Wright, who ordered school desegregation in 1960. Influential state judges such as Rose Elizabeth Bird, California's first woman Supreme Court Chief Justice, are also featured.
