Table 2.
CoCs or chemicals found within the EPA dataset at or above Florida’s residential SCTLs. The maximum values and 95% upper confidence limits (UCLs) from the EPA dataset and from the GISP and GIB samples collected 5 years later are shown. The values in bold correspond to levels that exceed Florida residential SCTLs.

a NM = Not Measured; b NA = Not Applicable; c BDL = Below Detection Limits. BDL values were variable within each chemical category; d UCL were not computed for tar samples because the numbers were too low. Only 2 tar samples were analyzed for metals and only 3 tar samples were analyzed for the organics in the EPA dataset. Only one tar sample was analyzed through the current study; e NC = Not Computed because only one sample was above detection limits.
