Passive samplers with multi-parameter water quality probe
Passive samplers (POCIS and mini-SPMDs) deployed in stream for assessment of chemical contaminants in the water; a multi-parameter water-quality probe (on left) measures water temperature, pH, and specific conductance during initial deployment.
