ABSTRACT:
There is provided a fluid sampling apparatus for withdrawing samples of groundwater or other fluids from a well or other monitoring site. The apparatus preferably includes pump means, packer means, conduit means and a wellhead assembly that are permanently installed at the well or monitoring site and are thereby dedicated thereto in order to avoid or minimize cross-contamination of samples from site to site. The packer is integral with the pump and isolates the groundwater below the packer in order to minimize the amount of groundwater which must be pumped in order to purge the well prior to taking an acceptable sample. The apparatus preferably also includes a removable and portable controller means adapted for easy and convenient transportation and connection to such dedicated fluid sampling components at various wells or monitoring sites.
