1.5"-2.25" Pneumatic Packer Model 12

Packer tests consist of isolating specific sections of a bedrock borehole with inflatable packers. Water-quality samples can then be collected and aquifer tests can be carried out. A series of such tests allows for the definition of the vertical distribution of water quality (usually contaminants) and hydraulic conductivity or pathways for water and contaminant movement in an aquifer.Monitoring water levels in nearby wells while pumping packed intervals can identify permeable intervals within an aquifer. Information from the packer tests can then be used to properly site the future location of monitoring wells. SolutionsSmaller packers designed to fit a submersible sampling pump can be used to replace " nested wells" to isolate the lower part of a monitoring well. Isolation by the packer allows reduced water volumes to be purged prior to sampling. This reduction can be beneficial because it can reduce purge times and may limit the handling and disposal of contaminated water.
