At the northern limit of the main landfill, a trench collects contaminated groundwater flowing north from the buried wastes. The groundwater collected in the trench is pumped to Lowry Landfill’s onsite water treatment plant located at the northern boundary of the site. Completed in 1998, this system is known as the North Toe Extraction System because of its location at the northern edge of the former landfill area, which is near the center of the Lowry Landfill site.
