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. 606 $aNutrient pollution of water$zMississippi River 606 $aMarine eutrophication$zMexico, Gulf of 606 $aHypoxia (Water)$zMexico, Gulf of 606 $aNonpoint source pollution$zUnited States 606 $aFertilizers$xEnvironmental aspects$zUnited States 606 $aWater$xPollution$zUnited States 606 $aAgricultural pollution$xEnvironmental aspects$zUnited States 606 $aEutrophication$zUnited States 606 $aWatershed management$zUnited States 615 0$aNutrient pollution of water 615 0$aMarine eutrophication 615 0$aHypoxia (Water) 615 0$aNonpoint source pollution 615 0$aFertilizers$xEnvironmental aspects 615 0$aWater$xPollution 615 0$aAgricultural pollution$xEnvironmental aspects 615 0$aEutrophication 615 0$aWatershed management 676 $a363.739 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910974537303321 996 $aNutrient control actions for improving water quality in the Mississippi River basin and northern Gulf of Mexico$94347487 997 $aUNINA
