McDonald's - Oskaloosa Rebuild Oskaloosa, IowaTerracon Project No. 08205113

Layering shown on this figure has been developed by the geotechnicalengineer for purposes of modeling the subsurface conditions asrequired for the subsequent geotechnical engineering for this project.Numbers adjacent to soil column indicate depth below ground surface.

This is not a cross section. This is intended to display the Geotechnical Model only. See individual logs for more detailed conditions.

Groundwater levels are temporal. The levels shown are representative of the dateand time of our exploration. Significant changes are possible over time.Water levels shown are as measured during and/or after drilling. In some cases,boring advancement methods mask the presence/absence of groundwater. Seeindividual logs for details.
