SimulProbe®Technologies, Inc. <br /> Maxi SimulProbe®Soil/Groundwater Mode <br /> 4.0 ASSEMBLY AND OPERATION: Soil/Groundwater Mode — Using <br /> Nitrogen Back Pressurization With the Water Canister and Vacuum <br /> Assist (Cased Hole or Mud Rotary Drilling Application) <br /> Instructions are the same as above with the additional step of using a peristaltic or <br /> vacuum pump to lift water into the water canister. Vacuum assist is not recommended <br /> when sampling for volatile compounds. <br /> 5.0 ASSEMBLY AND OPERATION: Water Canister Not Required - <br /> Soil/Groundwater Mode - Using Peristaltic Pump to Pump <br /> Groundwater to Surface (Cased Hole or Mud Rotary Drilling <br /> Application) <br /> This is a shallow (less than 25 feet) groundwater sampling technique for <br /> non-VOC sample collection. There is no Water Canister required when it <br /> is thought that the formation permeability is sufficient to allow water to be <br /> drawn through a peristaltic pump. <br /> The peristaltic pump technique will only work if the piezometric water level of the <br /> formation being sampled is 25 feet or less below the ground surface. Note: Suspended and <br /> dissolved solids will increase the fluid specific gravity and thus reduce the effective depth range <br /> of a peristaltic pump. <br /> 6.0 ASSEMBLY AND OPERATION: Soil/Groundwater Mode - Using Up- <br /> Hole Hammer, Hollow NW Rods and Sample Bailer(Cased Hole or <br /> Mud Rotary Drilling Applications) <br /> 6.1 Assemble the SimulProbe@ as in Section 3.0 of the Soil/Soil Gas SOP. <br /> 6.2 Attach a hollow NW rod to the top of the SimulProbe@ using a hollow <br /> NW/AW pin converter. This will allow fluids to pass through the Upper <br /> Reed Valve port at the bottom of the Sampler Head and into the hollow <br /> NW rods for collection by bailer. <br /> 6.3 Lower the SimulProbe@ to the bottom of the bore hole, adding more NW <br /> rods as needed. Use O-rings or Teflon paste between NW rod <br /> connections to prevent cross contamination from bore hole fluids. <br /> 6.4 Drive the SimulProbe@ 21 inches using an up-hole hammer on the top of <br /> the NW rod string. <br /> 6.5 Retract the SimulProbe@ 2 to 3 inches to expose the Circular Screen. <br /> The water sample will flow into the hollow NW rods. <br /> 6.6 Lower a decontaminated water level sensor inside the NW rods to <br /> determine when there is enough water to collect a sample. <br />
