Conrad Schaefer / This animation displays topographic and geologic information taken from an authorized Texas Commission on Environmental Quality Municipal Solid Waste (MSW) landfill permit. For lithology symbolized in subsurface wells, red = gravels (GW-GP-GM-GC), dark orange = clean sands (SW-SP), light orange = sand with fines (SM), yellow = sand with fines (SC), and gray = clays (CL-CH) -- (Universal Soil Classification System). The green represents the screened interval of a groundwater monitoring well. The blue layer is an approximation of the top water surface of the upper-most aquifer during a 2006 sampling event. The information shown in this animation is an approximation for demonstration purposes only. It is not intended to be used for engineering, geologic, surveying, regulatory, etc purposes.
