More 3M Chemicals Found in Twin Cities Lakes
Elevated levels of a chemical formerly manufactured by 3M Co. have been found in nine lakes in the Twin Cities area, reported Kare 11 News.
The PFO's (perfluorooctane sulfonate) found in the lakes had been used for decades by the company in its production of Scotchguard and firefighting foams. The company ceased production in 2002, however, high levels of the chemical still remain in three Minneapolis lakes and six lakes in surrounding areas.
The Minnesota Pollution Control Agency released a lakes study Tuesday that began after the discovery last spring of considerably high levels of PFOS in bluegills from Lake Calhoun in Minneapolis. State health officials promise to evaluate the findings and determine whether more fish consumption advisories should be released.
Paul Hoff, the MPCA's supervisor of environmental reporting and special studies, said that these nine lakes contained high enough levels of PFO's to possibly be cause concern. The lakes study found that the contamination is due to stormwater runoff.
Kare 11 reports the lakes with elevated levels of PFO's are as follows: Lake Johanna (Arden Hills), Cedar (Minneapolis), Harriet, Hiawatha, Jane, Keller, Powers, Red Rock and Tanners.
