The SP60 Sonic Groundwater Sampler is a packer based, deployable water sampling system designed for collecting groundwater samples thru Geoprobe® 6 in. Casing. The water sampling system includes an inflatable packer, 2 in. Stainless Steel screen, and an inflation manifold assembly. The assembly is commonly deployed inside 6 in. casing with standard 2 in. schedule 40 PVC. The packer is inflated via flexible tubing, inflation valve assembly, and air supply (not included). Manual air pumps or a small air tank are common sources for the compressed air needed to inflate the packer.
SP60 Water Sampling
The most common use of the SP60 Packer Sampler is to collect discrete groundwater samples thru Geoprobe® 6 in. casing. When inflated, the packer seals off the 2 in. Stainless Steel Screen section from any water that might be above the packer in the casing. In many drilling operations (for example sonic drilling) water is required in order to flush cuttings and advance the drill string. The water that is left in the casing is not desirable when taking groundwater samples, and normally has be purged from the casing before actual groundwater samples can be collected. The SP60 Packer Sampler helps to ensure the groundwater being sampled is representative of that particular interval, and prevents the screen section from being exposed to the water inside the casing.
The SP60 Packer Sampler can be used with multiple direct push and sonic sampling systems such as SDT60, 4x6, DT60, or 6x8 just to name a few. The modular design of the packer assembly also allows multiple packers to be used for different isolation options.
