AeroVironment Inc. was tasked to conduct a Phase II Stage I investigation at Williams AFB, near Phoenix, AZ. The objective was to confirm and to quantify the presence and extent of contamination at the fire protection training area 2 FPTA, liquid fuels storage area LFSA, surface drainage system - southwest, landfill, pesticide burial area, and surface drainage system - northwest. Drilling and soil sampling were conducted at the FPTA, FLSA, and landfill. Thirty-one holes were drilled in the three areas. Surface soil samples were collected along the two drainage channels. Also, a magnetometer survey was conducted at the pesticide burial area. A total of 272 samples were collected. Of the 272 samples collected, 204 were analyzed in the laboratory. Soil contamination was found at 1 small burn pit at FPTA, 2 drainage outfall at FPTA, 3 old AVGAS distribution system at LFSA, and 4 southwest drainage system. Magnetic anomalies buried drums were identified at the pesticide burial area. Recommendations made for Williams include 1 remove surface soils from the southwest drainage, 2 excavate and inspect the identified buried materials at the pesticide disposal area, 3 collect additional samples around contamination at the FPTA and LFSA.
