Document Summary

Arec 200: the chesapeake bay ecosystem: science, economics and policy problem set #1: questions are similar to what will be on the mid-term exam. Grading: 5% of course grade (total points 50) Short response (4 points each, 36 total): several physical characteristics of the chesapeake bay make it more difficult to restore than the average estuary or coastal sea. Most coastal sea"s mouths are open and the water freely flows in and out the ocean. What is a tmdl and how is it a diet: tmdl is the total maximum daily load, which establishes a limit for all sources of nitrogen, phosphorus and sediments. Discuss two issues: bacteria: the fecal bacteria in the anacostia makes the river a unsafe place for recreational uses, such as fishing and swimming. It is mainly caused by sanitary sewage leakage and combined sewage overflow. Stormwater runoffs: stormwater carries trash, sediments and toxins into the anacostia river.
