b. What construction activities would be regulated under the CWA? Why? (2 pts.) species that has a tissue lipid concentration of 1%, calculate the theoretical bioaccumulation potential (TBP) for the necessary organic contaminants in the marina, referensce area and HRS sediments (show your calculations). (3 pts.) c. Assuming a biota-sediment accumulation factor (BSAF) of 1.7 and using a test d. Based on your TBP predictions, do you think placement of the dredged material at the HRS would \"significantly\" reduce the bioaccumulation of DDE from the site? Why? (2 pts.) e. Does the quality of the marina dredged material meet CWA \"contaminant determination\" Section 404(b)(1) Guidelines existing for open-water discharge? Why? (2 pts.) . Based on existing information, would Tier 3 testing of the sediments be necessary? Why? (2 pts.) g Does discharge of the marina dredged material meet applicable New York State water quality standards? Why? (2 pts.)

Solution

The Clean Water Act (CWA) is the primary federal law in the United States governing water pollution. Its objective is to restore and maintain the chemical, physical, and biological integrity of the nation\'s waters by preventing point and nonpoint pollution sources, providing assistance to publicly owned treatment works for the improvement of wastewater treatment, and maintaining the integrity of wetlands. It is one of the United States\' first and most influential modern environmental laws. As with many other major U.S. federal environmental statutes, it is administered by the U.S. Environmental Protection Agency (EPA), in coordination with state governments. The Clean Water Act does not directly address groundwater contamination. Groundwater protection provisions are included in the Safe Drinking Water Act, Resource Conservation and Recovery Act, and the Superfund act. All waters with a \"significant nexus\" to \"navigable waters\" are covered under the CWA; however, the phrase \"significant nexus\" remains open to judicial interpretation and considerable controversy. The 1972 statute frequently uses the term \"navigable waters,\" but also defines the term as \"waters of the United States, including the territorial seas.\"[
