WebDec 28, 2024 · Porous surface samples - Because PCBs can migrate into porous surfaces (e.g., brick, masonry, concrete or wood) surface wipe sampling is not adequate to characterize the PCB concentration of porous surfaces. Instead, core samples should be collected on a bulk basis (i.e., mg/kg) to collect the top 0.5 to 2 cm of the porous surface.
