About this file

This image is a detailed aerial map titled "Groundwater Monitoring Locations" for the Truax Landfill in Dane County, Wisconsin, prepared by TRC Solutions in April 2016. The map shows a comprehensive grid of groundwater monitoring wells (marked MW-1, MW-3, MW-12, etc.), active and inactive landfill gas (LFG) probes, extraction wells, and various infrastructure like trench riser valves and condensate management points. The map includes surrounding street names such as Packers Avenue, International Lane, and Shopko Drive, with a dotted boundary indicating the limits of waste disposal area.

The map provides precise geospatial information using NAD83 HARN coordinate system and Dane County coordinate references. The legend details different monitoring well statuses (active, abandoned), LFG probe types, and infrastructure elements. Notes on the map indicate the base imagery is from USDA National Agriculture Imagery Program from 6/19/2013, and topographic contours and building footprints were supplied by the Dane County Land Information Office. The document serves as a critical reference for environmental monitoring and management of the Truax Landfill site, showing the strategic placement of monitoring equipment to track groundwater conditions and landfill gas emissions.
