The dirt sample location was located in Naples Fl. off of exit 107 about a mile east of interstate 75. The area where the soil was taken from was primarily a pine flat with little to no undergrowth, consisting of a shallow layer of pine needles over the dirt layer (Figure 2S). The soil itself is a white/ ivory color with small amounts of gray and tan mixed throughout (Figure 1S). The soil appears to be of fairly uniform consistency and lacks any large particles or organic matter visible to the naked eye. The particle size throughout is most likely classified as sand and the overall moisture content feels relatively low (no excess water on the bottom of the bag but sand particles stick together).
