The Screen Point 15 groundwater sampling system was the most widely used direct push system for environmental groundwater investigations for several years. Since then, Geoprobe Systems® has retired the Screen Point 15 system and introduced the Screen Point 16 system (1.6 in. OD screen sheath) which is designed for use under the more powerful GH60 hammer with the heavier 1.5 in. probe rods. These protected screen samplers have only five parts, including the grout plug, plus a few O-rings. Using either of these tools with O-rings on the rod fittings enables you to collect representative groundwater samples from a discrete interval using a bailer, bladder pump, or other device. The length of the screen exposed to the formation can be set from just a few inches to as much as 41-inches to let you select the sampling zone. Additionally, the same screens (Stainless Steel or PVC) can be used in both samplers. The grout plug at the base of the screen makes it possible to conduct bottom-up grouting with bentonite slurries or neat cement using any of the Geoprobe® GS Series grout machines. A PDF standard operating procedure (SOP) for the SP16 samplers is available for free to download.
The Screen Point 16 Groundwater Samplers are used to collect groundwater samples from unconsolidated materials at depths ranging from near ground surface to over 100 feet below grade. The depth that can be reached with the SP16 samplers is a function of the equipment and methods being used to advance the sampler (manual, static vehicle weight, or percussion probing), the formation being penetrated, and operator experience.
Screen Point 16 Advantages:
1. Driving
The assembled Screen Point 16 Groundwater Sampler is driven to the desired sampling depth using standard Geoprobe® rods.
2. Deployment
Extension rods are used to hold the screen in position while the rods and sheath are retracted. The screen sheath forms a mechanical annular seal above the screen interval.
3. Sampling
The tubing check valve can be used to sample and measure NAPLs within the screen interval as well as sample groundwater. A small bladder pump may be used to collect high-integrity VOC samples.
4. Grouting
Abandonment grouting can be conducted to meet ASTM guidelines. A high-pressure grout pump is used to pump grout into the probe hole as the screen and rods are extracted using the rod grip pull assembly.
The latching sampler allows the user to connect a pump, or other sample line, directly to the top of the downhole SP sampler. This isolates the SP sampler from water in the rod string above the sampler, thereby assuring sample integrity.
