Previous problems with leaks in this space caused suspected mold growth on the wall and pipe insulation in this records storage space.  3M Scotch Transparent Tease tape samples were taken from the surface.  The tape was placed on a microscope slide using clear fingernail polish as a mounting fluid.  Photos were taken with Foldscope microscope attached to a Samsung S-5 Cell phone.   Photos were cropped using Adobe Photoshop Elements 12.
