Low Cost, No Purge Groundwater Sampler These types of samplers are fast becoming a popular method for groundwater sampling on many Australian sites. Sleeve samplers make groundwater sampling a simple, three-step operation that can be more effective than purging or low-flow sampling. The low-cost, disposable sleeve captures a core of water from any discrete interval in the screened portion of the well with no change in water level and minimal disturbance to the water column. The sleeve is sealed except during sample collection, then re-seals itself, assuring that a formation quality sample is recovered. The tripod stand option provides a convenient place to hang a full sampler while filling sample bottles. Independent laboratory testing confirms that sleeve samplers are PFC/PFAS-free, based on analysis for 28 different PFCs at extremely low detection limits.
