' eO' icaC7ecknics Inc. • • G g Page 5 Fonzia ' SGWI Report Project No.: 774.2 June 10, 1999 ' 3.0 ANALYTICAL RESULTS Summarized below are the results of the s it and groundwater analysis. Soil • Low levels of Motor Oil were detected in the soil samples from GP-4, GP-5 and GP-13, ' all at 9 feet bgs. • Low levels of Motor Oil were detected in the soil samples from GP-14 at 12, 19, 28, and 33 feet bgs. ' • Low levels of Motor Oil were detected in the soil samples from GP-15 and GP-17 at 9.5 and 12 feet bgs. • Moderate levels of Motor Oil were detected in the soil sample from GP-6 at 9 feet bgs. This borehole is located outside of the xcavation performed in 1995. ' • Low levels of Phenol were detected in the 12-foot soil samples collected from GP-14 and GP-15. • The five LUFT metals were tested for and all were detected except cadmium. The levels ' detected in the boreholes that were drilled in the areas of motor oil contamination were equivalent to or lower then the levels d tected in the background borehole. Groundwater t • Low levels of Motor Oil were detected in the groundwater samples collected from GP-7, GP-8, GP-10, GP-11, GP-14 @12', GP 14 @ 33', GP-15 and GP-17. • Moderate levels of Motor Oil were detected in the groundwater samples from GP-4, GP- 5, GP-6, GP-9, GP-12 and GP-13. These samples were not filtered prior to being extracted. • Low levels of Bis(2-Ethylhexyl) Phthalate were detected in the groundwater sample ' collected at 33 feet in GP-14. • The five LUFT metals were tested for d all were detected except cadmium. The levels detected in the boreholes that were dri led in the areas of motor oil contamination were equivalent to or lower then the levels dc tected in the background borehole. Discussion Low levels of motor oil have been found in several areas of the site, with the primarily t location around the former storage area. The wide spread nature of the oil points to a couple possibilities as to sources. • One possibility is that oil may have been sprayed on the property to control dust during ' the early days of operation of the Fortifiber plant. This practice was common and can lead to widespread, low levels of motor oil as seen at this site. • A second possibility is that waste oil handling practices at the facility were sloppy and the used oil may have been poured out on the ground surface wherever proved convenient. In either of these cases, the oil is mostly in low concentrations, is no longer being added to and will most likely degrade with time. ' Phenol is obtained from coal tar or manuf tured from reactions with NaOH. It is generally used in disinfectants, resins and dyes. Phenol is approximately 8% soluble in water. ' However it has not been detected in the groundwater at the site, only in the soil. The source for the Phenol that was detected in the 2-foot soil samples from GP-14 and GP-15 is difficult to determine. It is possible that it ame from: 1
