St. Paul, MN (NNCNOW.com) --- A new study released by the Minnesota Pollution Control Agency shows that prescriptions, household chemicals and illegal drugs have been found in many of Minnesota's lakes and rivers.
The MPCA chose 50 randomly selected lakes throughout Minnesota and analyzed them for 125 different chemicals.
The results of the study showed that the insect repellent DEET was found in 76 percent of the lakes sampled, making it the most frequently detected chemical.
Chemicals not previously anazlyzed- including cocaine, the antidepressant amitriptyline and the veterinary drug carbadoz were often detected in the lakes. In fact, cocaine was found in nearly 1/3 of the lakes tested in Minnesota. Cocaine was detected in lakes generally without public access, which means it is being introduced to the lakes via indirect means. MPCA officials said the detection of cocaine was unexpected and say that it was probably transported long distances through the atmosphere.
All chemicals found were detected at low concentrations but are still of concern since they have the potential to adversely affect fish and aquatic organisms even at extremely low levels.
The MPCA plans to continue testing the waters on a rotating five-year basis to identify trends that may occur.
