2.) Surface samples were collected from just above the landfill surface immediately adjacent to a surface fissure.3.) Samples were collected by inserting a probe directly into a fissure in the landfill cover where smoke is being emitted.4.) Except where noted, all regulatory limits are based on published OSHA standards
