While the substance levels in all the collected samples are below detectable limits of the
laboratory instruments some odors can certainly be detected by the nose of sensitive people. The ability
to smell substances at very low concentrations (on the order of parts per trillion, parts per quadrillion and
even lower for burning and smoke odors) is very disturbing to people. To further compound the problem
odors at these levels may cause headaches and nausea, causing people to question the impact on their
health..
