This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Great Lakes and the streams draining to them provide an abundance of ecosystem services, including habitat, water resources, and recreational opportunities. The success and wellbeing of these water bodies are impacted by a variety of factors, including invasive species and septic systems. Along the shoreline of the Great Lakes, invasive species, such as Phragmites and Typha, are a major concern to the coastal wetlands. Within the inland river systems, near-shore septic systems can create elevated levels of nutrients that can have a collection of negative impacts. Both of these threats ultimately relate back to the presence and application of nutrients such as nitrogen and phosphorus. We first address the landscape conditions that allow for coastal wetland invasion. Using machine learning algorithms, we were able to quantify relationships between the presence of invasive species in coastland wetlands, and a variety of landscape scale variables - primarily the nutrient loads of nitrogen and phosphorus. We determined that high invasion is most strongly associated with nitrogen loading above 118 kg/ha/yr within the watersheds derived from the invaded wetlands. We then address how septic systems could be contributing to nutrient loads within the Manistee and Au Sable Rivers of Michigan. We modeled groundwater flow and the transport of nutrients to assess how competently septic systems are retaining nutrients. On average, septic systems allow 88% of introduced nitrogen, and 49% of phosphorus, to enter groundwater. These findings will inform watershed management and provide a better understanding of the effectiveness of septic systems.

Book Synopsis Clean Coastal Waters by : National Research Council
Download or read book Clean Coastal Waters written by National Research Council and published by National Academies Press. This book was released on 2000-08-17 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental problems in coastal ecosystems can sometimes be attributed to excess nutrients flowing from upstream watersheds into estuarine settings. This nutrient over-enrichment can result in toxic algal blooms, shellfish poisoning, coral reef destruction, and other harmful outcomes. All U.S. coasts show signs of nutrient over-enrichment, and scientists predict worsening problems in the years ahead. Clean Coastal Waters explains technical aspects of nutrient over-enrichment and proposes both immediate local action by coastal managers and a longer-term national strategy incorporating policy design, classification of affected sites, law and regulation, coordination, and communication. Highlighting the Gulf of Mexico's "Dead Zone," the Pfiesteria outbreak in a tributary of Chesapeake Bay, and other cases, the book explains how nutrients work in the environment, why nitrogen is important, how enrichment turns into over-enrichment, and why some environments are especially susceptible. Economic as well as ecological impacts are examined. In addressing abatement strategies, the committee discusses the importance of monitoring sites, developing useful models of over-enrichment, and setting water quality goals. The book also reviews voluntary programs, mandatory controls, tax incentives, and other policy options for reducing the flow of nutrients from agricultural operations and other sources.
Book Synopsis Riverine Ecosystem Management by : Stefan Schmutz
Download or read book Riverine Ecosystem Management written by Stefan Schmutz and published by Springer. This book was released on 2018-05-08 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book surveys the frontier of scientific river research and provides examples to guide management towards a sustainable future of riverine ecosystems. Principal structures and functions of the biogeosphere of rivers are explained; key threats are identified, and effective solutions for restoration and mitigation are provided. Rivers are among the most threatened ecosystems of the world. They increasingly suffer from pollution, water abstraction, river channelisation and damming. Fundamental knowledge of ecosystem structure and function is necessary to understand how human acitivities interfere with natural processes and which interventions are feasible to rectify this. Modern water legislation strives for sustainable water resource management and protection of important habitats and species. However, decision makers would benefit from more profound understanding of ecosystem degradation processes and of innovative methodologies and tools for efficient mitigation and restoration. The book provides best-practice examples of sustainable river management from on-site studies, European-wide analyses and case studies from other parts of the world. This book will be of interest to researchers in the field of aquatic ecology, river system functioning, conservation and restoration, to postgraduate students, to institutions involved in water management, and to water related industries.
Book Synopsis Contaminants of the Great Lakes by : Jill Crossman
Download or read book Contaminants of the Great Lakes written by Jill Crossman and published by Springer Nature. This book was released on 2020-09-17 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the globally important freshwater resource of the Great Lakes, which is currently threatened by contaminants that compromise water quality and impact its ecological and economic health. Divided into four parts, this volume covers historic, current and emerging sources of contamination from heavy metals and persistent organic pollutants to microplastics; and identifies their ecological impacts. Due to factors ranging from rapidly changing land use practices, climate change and our emerging understanding of their impact on biological, chemical and physical interactions, the effectiveness of management strategies has proven highly variable. Continued enhancements in the rate of lake recovery are required to sustain the health of the Great Lakes. Accordingly, the book also explores recent advances in contaminant detection, along with future steps forward in lake management approaches. Revealing our current knowledge gaps and providing a roadmap towards sustainable solutions, the book offers a valuable asset for scientists, managers and the public alike.

Workgroup on Parties Implementation and published by Windsor, Ont. : International Joint Commission. This book was released on 2000 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: The year 1998 marked the 20th anniversary of the final reports of the Commission's Pollution From Land Use Activities Reference Group (PLUARG). PLUARG produced a body of work that remains the cornerstone of current thinking about non-point source pollution in the Great Lakes and elsewhere. Twenty years after PLUARG, the Workgroup on Parties Implementation sought to assess the status of non-point source pollution control in the Great Lakes basin, particularly progress by the Parties under Annexes 3 and 13 of the Great Lakes Water Quality Agreement. To that end, the Workgroup sponsored a special session at the Great Lakes soil erosion and sediment control conference, held in Toledo, Ohio, September 16-18, 1998. This report summarizes the findings of that session.

Available in PDF, EPUB and Kindle. Book excerpt: Water quality in many regions of the Great Lakes Basin (GLB) has deteriorated due to numerous anthropogenic drivers, including increases in agricultural area, increased fertilizer use, intensive livestock production, and increases in human population densities. Excessive nutrient inputs from both point and non-point sources have accelerated eutrophication in inland watersheds and in receiving water bodies, and policy goals have recently been set to reduce phosphorus loading to Lake Erie by as much as 40%. Under such pressures, it is crucial to better our understanding of nutrient transport across the GLB and to identify key watershed drivers of both seasonal and annual nutrient loading from watersheds to the lakes. In this research study, I have utilized numerous metrics to characterize nutrient dynamics in Great Lakes Watersheds across a gradient of human impacts and have attempted to identify key controls on biogeochemical signatures. As a part of this work, I paired water quality data from over 200 Great Lakes watersheds with land use and climate data to identify dominant controls on stream nutrient concentrations at the annual, seasonal, and event scales. At the annual scale, standardized regression analysis identified significant relationships between flow-weighted concentration (FWCs) and selected catchment characteristics. FWCs were found to be strongly linked to land-use variables such as combined agricultural and urban land, wetlands and tile drainage. Our quantification of these relationships was used to create spatial maps of annual nutrient concentrations and loads and to identify nutrient hotspots across the GLB. Specifically, high nutrient concentrations and export were observed in the Maumee and Sydenham River catchments, whereas lower concentrations and loads were found in Lake Superior catchments. At the seasonal scale, three primary seasonal nutrient regimes were identified: (1) 'in-phase' (positive correlation between monthly concentrations and discharge), (2) 'out-of-phase' (negative correlation), and (3) 'stationary' (no significant relationship). While in-phase seasonality was found to be the most common concentration regime for watersheds with higher levels of agricultural land use, nitrate seasonality in particular was found to be muted in watersheds with the highest agricultural land use, but to be more extreme in watersheds with less agriculture but higher amounts of forested area and higher wetland densities. Out-of-phase seasonality was found to be significantly associated with higher population densities and higher percent urban areas. At the event-scale, concentrations were found to be more variable with discharge for phosphorus than for nitrate. Additionally, Lake Erie showed significantly lower concentration variability in relation to discharge compared to all the other Lakes. As the Lake Erie basin also has higher agricultural land use than the other lakes, the more chemostatic concentration dynamics in these watersheds appears to be linked to agricultural nutrient use and suggests that agricultural nutrient legacies may be an important driver of current patterns in nutrient delivery to the lakes.
