' Work Plan-Soil and Groundwater Investigation Herman&Helen's Marina May 30, 1995 Page-5- 1 A Teflon bailer will be lowered into the sampling chamber and a groundwater sample will be ' collected. The bailer sample will be inspected for free product, petroleum odor, and sheen. The sample will be gently poured into two (2) 40-m1 glass volatile organic analyses (VOA) vials, and one ' (1) 1-liter amber glass bottle. The sample containers will be sealed, labeled, and placed in a cooler chilled with Blue Ice for delivery under chain-of-custody procedures to FGL Laboratory, in Stockton, California for analyses. 3.5 Laboratory Analysis ' The soil and groundwater samples collected for chemical analyses will be analyzed for benzene, toluene, ethyl benzene, and total xylenes (BTEX) by EPA Method 8020 (602 for water), for total petroleum hydrocarbons quantified as gasoline (TPH-G) by Method 8015/Modified 5030, and for total petroleum hydrocarbons, quantified as diesel (TPH-D) by Method 8015/Modified 3015. The ' analytical methods and analytical detection limits are presented in Table 1, below.

The report will include: (1) a discussion of the site background, (2) a description of the fieldwork conducted at the site, (3) the laboratory analytical results, (4) a scaled site plan, (5) ' drilling logs, (6) conclusions, and (7) recommendations.
