Data collection on Round Lake began in 1991. In 2004 a final ec which identified unacceptable risk to benthic (the bottom of a body of water) organisms in Round Lake. The US Army submitted feasibility studies in 2004 and 2009, however both were rejected by the MPCA and EPA. An extensive investigation of Round Lake sediment was conducted grid pattern every 200 feet across the lake. Up to seven samples at different depths were taken from every core. The investigation showed that most of the heavy met copper, zinc, chromium, and cadmium) was in the uppermost six in contamination was heavier in locations nearest the outflow pipe from TCAAP. The US Army submitted revised feasibility studies in 2012 and 2013, which were also rejected by the MPCA an. In response to a question, MPCA and EPA staff replied that their produced no reason to suspect that barrels may have been dumped in Round Lake. Non contamination from any source other than stormwater runoff. Representatives of the US Fish and Wildlife Service (FWS) discusine of their acquisition of Round Lake as follows: 1973 The US Army determined Round Lake to be surplus. 1974 Round Lake plus approximately 29 acres of upland land was transf Department of the Interior. 1976 The Minnesota Valley National Wildlife Refuge (MVNWR) was created. 1978 Round Lake became a management unit of MVNWR. 1997 Congress approved the National Wildlife Refuge System Improvemen Although FWS owns Round Lake, the US Army remains legally responnd any remediation or restoration required. The lake is being kept at human or waterfowl exposure to the contaminated sediment. Accor healthier and provide better aquatic habitat if the lake level was allowed to naturally fluctuate. Long- term FWS plans for Round Lake include a trail around the entire k for fishing and observation. FWS wants to see a two-part solution that addresses not only remediation, but also restoration of natural resources. The EPA presented information on the superfund process and the F Army is the lead agency for the Feasibility Study, however the EWhen evaluating the proposed alternatives for action, the EPA considers the following: 1.To what extent does the remedy reduce contaminants? 2.To what extent does the remedy reduce risks to humans and wildli 3.What is the short-term effectiveness of the remedy? 4.What is the long-term effectiveness of the remedy?
