' • kn KLEINFELDER ' soil sample was characterized as a gravelly, silty sand. The grain size analysis showed 20.2% of the sample as gravel, 27.3% silty/clay, and 52.5% sand. Only 27.3% of the sample passed the #200 sieve. The permeability of the 120-foot soil sample was 9.6 x 10-8 (cm/sec). The 120-foot soil sample was characterized through the grain size analysis as light brown clayey fine sandy ' silt. The percentages of the components of the soil sample at 120-foot were 65% silt, 19% sand, and 16% clay. Approximately 81% of the sample passed the #200 sieve. Two soil samples collected from TW-2 were also analyzed in an undisturbed state. The soil ' samples in TW-2 were collected from the 5-foot and 26'/2 foot intervals. The soil samples collected from the 5-foot interval had a permeability of 9.28 x 10-6 (cm/sec) The 5-foot soil sample was characterized as sandy silty/clay with 24.7% sand, and 75.3% silt/clay. The ' permeability of the 26%2 foot soil sample in TW-2 was 4.14 x 10.7 (cm/sec). The 26%2 foot soil sample was characterized through the grain size analysis as green sandy clayey silt. The soil sample consisted of 59% silt, 33% clay, and 8% sand. A total of 92% of the sample passed the #200 sieve. ' A groundwater sample was collected for analysis from each deep boring. The groundwater ' samples were analyzed for sodium, chloride, total dissolved solids, dissolved inorganic solids, and specific conductivy.
