The MPCA recently held an online public meeting to provide information about options being considered for landfill redesign at the Freeway Landfill and Dump in Burnsville.
Freeway Landfill and Dump are former waste disposal areas unfortunately located adjacent to the Minnesota River at Interstate 35W in Burnsville. Six million cubic yards of buried waste remain and are a threat to groundwater and the Minnesota River.
Pumping to lower the groundwater levels at the adjacent Kraemer Quarry has lowered the water table and kept the groundwater from coming in contact with the waste. When the quarry stops operating in the future, the pumping will stop and the water table will rise. The expected future changes in groundwater movement pose a threat to the drinking water supply of Burnsville and Savage and to the Minnesota River. Drinking water supply wells in the area are tested regularly, and the water currently meets drinking water standards.
The MPCA is proposing two options. One option involves digging up the waste and rebuilding the landfill (dig and line option) to prevent migration of the contaminants. The second option would move the waste to a new location (dig and haul option), one with proper containment systems.
