  21. 21 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”

  22. 22 Installation Challenges/ Differences from Above Ground Packaging to transport through a cave Finding a location with steady water Securing SPMD samplers for surge events Hiding the SPMD Sampler or Labeling the SPMD Sampler for your anticipated finders (Cavers vs. Spelunkers)
