Download or read book Environmental and Water Quality Operational Studies Macroinvertebrate Gear Evaluation written by Larry G. Sanders and published by . This book was released on 1986 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies were conducted to evaluate the effectiveness of nine methods for collecting macroinvertebrates associated with dikes, revetments, and sandbar habitats. Data were collected on the Lower Mississippi River between river miles 440 and 448. The nine methods evaluated included circular rock basket implants, rock samples, the push sled, the diaphragm pump, the electroshocker, articulated concrete matress (ACM) implants, ACM slabs, ACM blocks, and a modified Hess sampler. Some gear types were used to test diel variations in the macroinvertebrate communities while others were used to obtain information on community structure and seasonal variation at dike, revetment, and sandbar habitats.

This book was released on 1986 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was conducted to evaluate the effectiveness of five different collecting gears in sampling larval fishes associated with dikes and revetments. The tests were conducted on the Lower Mississippi River at mile 508.8 and miles 447-448. The five collecting gears used were: Plankton nets fished at discrete depths in the water column of a dike pool and the main channel; a push sled; a diaphragm pump; an electroshocker; and basket implants. These gears were used during the day and night to describe diel and temporal changes in the larval fish community in main channel, dike pool, dike, revetment, and sandbar habitats. The discrete depth net gear was effective in documenting the vertical, diel, and temporal distribution of ichthyoplankton drift in the main channel and dike pool habitats. Similarities and differences in ichthyoplankton abundance and diversity occurred between habitats. The most notable observation was the comparable abundance among like depth strata between habitats in May. In June, the surface stratum at each habitat contained a far greater abundance of larvae than the samples collected at lower depths. The push sled was effective for sampling shallow water in the vicinity of sandbars. Use of the sled revealed diel and temporal differences in the shallow-water ichthyoplankton.

This book was released on 2000-02-17 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1997, New York City adopted a mammoth watershed agreement to protect its drinking water and avoid filtration of its large upstate surface water supply. Shortly thereafter, the NRC began an analysis of the agreement's scientific validity. The resulting book finds New York City's watershed agreement to be a good template for proactive watershed management that, if properly implemented, will maintain high water quality. However, it cautions that the agreement is not a guarantee of permanent filtration avoidance because of changing regulations, uncertainties regarding pollution sources, advances in treatment technologies, and natural variations in watershed conditions. The book recommends that New York City place its highest priority on pathogenic microorganisms in the watershed and direct its resources toward improving methods for detecting pathogens, understanding pathogen transport and fate, and demonstrating that best management practices will remove pathogens. Other recommendations, which are broadly applicable to surface water supplies across the country, target buffer zones, stormwater management, water quality monitoring, and effluent trading.

This book was released on 2020-01-15 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the basic principles for evaluating water quality and treatment plant performance in a clear, innovative and didactic way, using a combined approach that involves the interpretation of monitoring data associated with (i) the basic processes that take place in water bodies and in water and wastewater treatment plants and (ii) data management and statistical calculations to allow a deep interpretation of the data. This book is problem-oriented and works from practice to theory, covering most of the information you will need, such as (a) obtaining flow data and working with the concept of loading, (b) organizing sampling programmes and measurements, (c) connecting laboratory analysis to data management, (e) using numerical and graphical methods for describing monitoring data (descriptive statistics), (f) understanding and reporting removal efficiencies, (g) recognizing symmetry and asymmetry in monitoring data (normal and log-normal distributions), (h) evaluating compliance with targets and regulatory standards for effluents and water bodies, (i) making comparisons with the monitoring data (tests of hypothesis), (j) understanding the relationship between monitoring variables (correlation and regression analysis), (k) making water and mass balances, (l) understanding the different loading rates applied to treatment units, (m) learning the principles of reaction kinetics and reactor hydraulics and (n) performing calibration and verification of models. The major concepts are illustrated by 92 fully worked-out examples, which are supported by 75 freely-downloadable Excel spreadsheets. Each chapter concludes with a checklist for your report. If you are a student, researcher or practitioner planning to use or already using treatment plant and water quality monitoring data, then this book is for you! 75 Excel spreadsheets are available to download.
