Results
The SPMDs installed into Beacon Cave yielded the most significant PCB detections in the study area
The detections from SPMDs installed into Beacon Cave were approximately double that of the next highest “hits”

Installation Challenges/ Differences from Above Ground
Packaging to transport through a cave
Finding a location with steady water
Hiding the SPMD Sampler or
Labeling the SPMD Sampler for your anticipated finders
(Cavers vs. Spelunkers)
Securing SPMD samplers for surge events
