What is being done to establish nutrient criteria?

What will be an ideal response?


"Beginning in 2001, the EPA began publishing water quality nutrient criteria aimed at preventing and reducing the eutrophication that impacts so many bodies of water. The agency listed its recommended criteria for causative factors—nitrogen and phosphorus—and criteria for response factors: chlorophyll as a measure of phytoplankton density and a measure of water clarity. The EPA divided the country into ecoregions and determined criteria levels deemed appropriate for the specific region. Like the other water quality criteria, the nutrient criteria are provided as targets for the states as they address their water pollution (and especially eutrophication) problems."
