The Minnesota Pollution Control Agency has issued a letter of support for the alum treatment on Blue Lake. You can view the letter here. The letter declares that the MPCA approves the alum treatment on Blue Lake, and that they require the lake's pH is monitored during the treatment. The Isanti SWCD will monitor Blue Lake for a variety of lake health measurements (including pH) before, during and after the treatment.
