A passive sampling device is provided that is comprised of a member having a first surface and a second surface opposite the first surface and a hole through the member extending from the first surface to the second surface. An adsorbent material is positioned between two mesh members. The adsorbent material allows for efficient and selective removal of organic molecules, such as, for example, perfluoroalkyl substances.

Passive sampler

An in-situ monitoring tool is provided that is compromised of a non-reactive medium, a reactive medium, or a combination thereof, contained in a water-permeable mesh. The tool is placed in an aquifer for a predetermined amount of time to allow the medium(s) to act as a substrate that collects minerals from the aquifer for analysis.
