A Supplemental Report Regarding the Environmental Contamination From TexPet’s E&P Activities

smelled of crude oil and produced a reading of 6.5 ppm using a photo‐ionization detector (PID), which detects volatile organic compound vapors in the air above the water (see Figure 3.4‐5). Figure 3.4‐4 Hand dug well at SSF‐43 in April 2014 ‐ water level is about 7 feet below ground surface

When we returned to investigate SSF‐43 in late June and July 2014 (during the wet season), there was standing water near the well, and the water level in the well was just 1 foot below the ground surface. Furthermore, PID readings from the well did not indicate the presence of volatile organic vapors. On the day we collected a sample from the well, the water level had dropped to 4.5 feet below the ground surface but the PID reading was still at a background level (see Figure 3.4‐6).
