| Fish Statistics and Advisories |
No PFOS found in lake Sarah fish netted in last summers survey. The Minnesota Pollution Control Agency (MPCA) collected 381 fish from 20 area lakes and 2 rivers last spring and summer. The fish sampling was part of MPCA’s response to finding elevated levels of perfluorochemicals in fish from Lake Calhoun in Minneapolis in 2007. About 30 lakes in the metro area were selected for sampling to see if the Calhoun findings were unusual or whether other metro lakes also could be affected. Fish collected were analyzed for 13 different PFC compounds, those tested from Sarah included 7 bluegills, 5 crappies, and 5 Northern Pike. Of the 13 PFC compounds, only PFOS (perfluorooctane sulfonate) has been found to accumulate in fish tissue. 3M manufactured the chemical for decades for use in Scotchgard, firefighting foams and other products before ceasing production in 2002. MPCA reports (Star Tribune 1/30/08) that Sarah was among the metro lakes that showed little or no trace of PFOS. The entire report can be viewed by this link.
Fish Consumption Advisories. Several residents have asked about the consumption recommendations for our lake too. Our lakes specific advisories are shown in the window below. The Minnesota Department of Natural Resources (DNR), the Minnesota Pollution Control Agency (MPCA), and the Minnesota Department of Health collaborate in producing the fish consumption advisory. Each year, the DNR collects fish from lakes and rivers for testing. Minnesota has 6,000 fishable lakes. Fish from nearly 1,000 lakes and streams in Minnesota have been tested for contaminants.
All waters from which fish have been tested are listed in the tables that can be found by this link to the MN Dept. of Health website. The waters that have been tested are not necessarily more contaminated than those not tested. These guidelines are based on the contaminant level measured in fillets. |
