Samplers used for sampling hydrophilic organic chemicals from water
Passive Sampling Research—Columbia, Missouri. The polar organic chemical integrative sampler (POCIS - on the left) and semipermeable membrane devices (SPMDs - on the right) samplers are used for sampling hydrophilic organic chemicals from water. The SPMDs sampler can also be deployed for air sampling.

A saltwater tracer was injected into the shallow aquifer
Hydrogeophysics Laboratory — Storrs, Connecticut. A saltwater tracer was injected into the shallow aquifer at a uranium-contaminated site in Colorado and monitored for 28 days using a combination of geophysical and well-sampling arrays; the sampling array is marked by the white standpipes adjacent to the central injection tank.
