i contamination and the presence of groundwater Once groundwater was encountered, the hydropunch sampler was attached to the drive rod and driven into the formation for obtaining a discrete water sample The limited access direct push rig was unable to core much below the 70 foot depth An auger rig was then used for the deeper cores California Split Spoon (CSS) samplers were driven without liners in three foot intervals and then retrieved The boring was then augered advanced to the cored depth, and then a CSS sampler was again driven to obtain soil cores This coring, augering method advanced to the total depth of the hole If a water bearing formation was encountered, a hydropunch sampler was then driven into the water bearing zone for the recovery of water samples HYDROPUNCH WATER SAMPLING METHOD The borings or direct push probe holes were advanced to within three feet of the interval for water sampling The drilling assembly was removed and the hydropunch attached to a drill rod that pushed the hydropunch to the desired sampling depth The hyropunch was connected to the drive point Once the sample depth was achieved, the drive rods (1 75 inch diameter hollow rods) were retracted, exposing the filter screen and allowing groundwater infiltration A small diameter bailer was used to collect groundwater samples through the hollow rod Three hydropunch samples failed at the following core hole intervals due to mud clogging the inner rod, T3-2 at the 80 to 82 75 and 86 to 89 foot intervals and at T3-3 from the 81 to 82 foot interval SAMPLE PRESERVATION Soil samples collected from the direct push continuous core boreholes were preserved by covering the acrylic sample sleeve ends with plastic caps Soil samples collected from the auger/CSS drilling were first field screened with a PID containing a 10 6 ev bulb The highest response interval within the CSS was then sleeved with a 2 inch diameter by 3 inch length stainless steel sleeve and then capped with Teflon and plastic end caps Each sample sleeve (acrylic or stainless steel) was labeled with the site name, date, time, sample location, and analyses to be performed Each labeled soil sample was placed in a separate zip lock bag, deposited in an ice chest, and cooled to 4°C The water samples collected from the first water bearing zone or hydropunch sampler were decanted from the mini bailer into and completely filling three (no headspace) 40 cc VOAs that contain HCI as a preservative The VOAs were then capped with teflon septum caps, labeled with the site name, date, time, sample location, and analyses to be performed Each labeled water sample was placed in individual zip lock bags prior to deposit into an ice chest, and cooled to 40C The samples and accompanying chain-of- custody documentation were delivered to a California State certified analytical laboratory 5 ARC Pump, ASSESSMENT 2006
