Book Synopsis Nutrient Control Actions for Improving Water Quality in the Mississippi River Basin and Northern Gulf of Mexico by : National Research Council
Download or read book Nutrient Control Actions for Improving Water Quality in the Mississippi River Basin and Northern Gulf of Mexico written by National Research Council and published by National Academies Press. This book was released on 2009-07-13 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: A large area of coastal waters in the northern Gulf of Mexico experiences seasonal conditions of low levels of dissolved oxygen, a condition known as hypoxia. Excess discharge of nutrients into the Gulf of Mexico from the Mississippi and Atchafalaya rivers causes nutrient overenrichment in the gulf's coastal waters and stimulates the growth of large algae blooms. When these algae die, the process of decomposition depletes dissolved oxygen from the water column and creates hypoxic conditions. In considering how to implement provisions of the Clean Water Act to strengthen nutrient reduction objectives across the Mississippi River basin, the U.S. Environmental Protection Agency (EPA) requested advice from the National Research Council. This book represents the results of the committee's investigations and deliberations, and recommends that the EPA and U.S. Department of Agriculture should jointly establish a Nutrient Control Implementation Initiative to learn more about the effectiveness of actions meant to improve water quality throughout the Mississippi River basin and into the northern Gulf of Mexico. Other recommendations include how to move forward on the larger process of allocating nutrient loading caps-which entails delegating responsibilities for reducing nutrient pollutants such as nitrogen and phosphorus-across the basin.

This book was released on 2012-12-31 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most water resources managers, scientists, and other experts would agree that nonpoint source pollution is a more pressing and challenging national water quality problem today than point source pollution. Nonpoint sources of pollutants include parking lots, farm fields, forests, or any source not from a discrete conveyance such as a pipe or canal. Of particular concern across the Mississippi River basin (MRB) are high levels of nutrient loadings--nitrogen and phosphorus--from both nonpoint and point sources that ultimately are discharged into the northern Gulf of Mexico (NGOM). Nutrients emanate from both point and nonpoint sources across the river basin, but the large majority of nutrient yields across the MRB are nonpoint in nature and are associated with agricultural activities, especially applications of nitrogen-based fertilizers and runoff from concentrated animal feeding operations. Improving Water Quality in the Mississippi River Basin and Northern Gulf of Mexico offers strategic advice and priorities for addressing MRB and NGOM water quality management and improvements. Although there is considerable uncertainty as to whether national water quality goals can be fully realized without some fundamental changes to the CWA, there is general agreement that significant progress can be made under existing statutory authority and budgetary processes. This book includes four sections identifying priority areas and offering recommendations to EPA and others regarding priority actions for Clean Water Act implementation across the Mississippi River basin. These sections are: USDA's Mississippi River Basin Healthy Watersheds Initiative; Numeric Water Quality Criteria for the northern Gulf of Mexico; A Basinwide Strategy for Nutrient Management and Water Quality; and, Stronger Leadership and Collaboration.

This book was released on 2008-02-08 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mississippi River is, in many ways, the nation's best known and most important river system. Mississippi River water quality is of paramount importance for sustaining the many uses of the river including drinking water, recreational and commercial activities, and support for the river's ecosystems and the environmental goods and services they provide. The Clean Water Act, passed by Congress in 1972, is the cornerstone of surface water quality protection in the United States, employing regulatory and nonregulatory measures designed to reduce direct pollutant discharges into waterways. The Clean Water Act has reduced much pollution in the Mississippi River from "point sources" such as industries and water treatment plants, but problems stemming from urban runoff, agriculture, and other "non-point sources" have proven more difficult to address. This book concludes that too little coordination among the 10 states along the river has left the Mississippi River an "orphan" from a water quality monitoring and assessment perspective. Stronger leadership from the U.S. Environmental Protection Agency (EPA) is needed to address these problems. Specifically, the EPA should establish a water quality data-sharing system for the length of the river, and work with the states to establish and achieve water quality standards. The Mississippi River corridor states also should be more proactive and cooperative in their water quality programs. For this effort, the EPA and the Mississippi River states should draw upon the lengthy experience of federal-interstate cooperation in managing water quality in the Chesapeake Bay.

Available in PDF, EPUB and Kindle. Book excerpt: Phosphorus (P) in rivers and streams in the Mississippi River Basin (MRB) is a contributing nutrient to hypoxia in the Gulf of Mexico and impacts local water quality. Although nitrogen has been extensively studied and attributed to be the main nutrient causing the Gulf hypoxic zone, P has increasingly been recognized as having more of an effect than was previously thought. The primary inputs of P to rivers and streams are through surface runoff or tile drainage from agricultural fields and from point sources, primarily sewage effluent. The objective of this study was to analyze the spatial pattern of P inputs and outputs in the MRB as they relate to riverine P yields to the Gulf of Mexico and to determine the counties in the MRB that have the highest yields of P and the most critical factors causing this P loss. A database of factors contributing P to the environment was constructed for each county in the MRB from 1997 through 2006 including data on fertilizer application, major crop acreage and harvest, animal numbers for manure inputs and human population. Landscape and climate characteristics of tile drainage, soil characteristics, slope and precipitation were also included. Riverine yields of total P (TP), dissolved reactive P (DRP) and particulate P (PP) for 113 watersheds within the MRB were related to these factors to create multiple regression and spatial error regression models to predict P yields throughout the basin. The fraction of the land planted in crops, sewage effluent P inputs and precipitation were found to best predict TP yields with a spatial error model (R2=0.47). Dissolved reactive P yields were predicted by fertilizer P inputs, sewage effluent P inputs and precipitation in a multiple regression model (R2=0.46), whereas PP yields were explained by crop fraction, sewage effluent P inputs and soil bulk density in a spatial error regression model (R2=0.499). Inputs of P from animal manure were not found to be significant in any model predicting P yields, which contrasts with the results of the USGS SPARROW model. Overall, the Cornbelt region of the upper Midwest, where there is a large amount of cropland and fertilizer application, had the counties with the greatest P yields. This analysis of P in the MRB helps to point out specific areas where P reductions are needed to limit the occurrence of Gulf hypoxia and improve local water quality.

Book excerpt: Summary of a Workshop on Mississippi River Water Quality Science and Interstate Collaboration summarizes presentations and discussions of Mississippi River and basin water quality management, monitoring, and evaluation programs that took place at a workshop that was held in St. Louis on November 18-19, 2013. The workshop examined a wide array of challenges and progress in water quality monitoring and evaluation in states along the Mississippi River corridor, and provided a forum for experts from U.S. federal agencies, the Mississippi River states, nongovernmental organizations, and the private sector to share and compare monitoring and evaluation experiences from their respective organizations.
