Ref. Method and Comment:

EPA 200.8 Rev. 5.4: The arsenic and lead results were confirmed on 02/03/2015.

SM 2540 D-97: Sample has large amount of particulate matter.

DEP SOP: GC-011-5 (based on EPA 608 and 617): MDL for Dicofol, Endrin aldehyde, Dieldrin, DDD-p,p' and DDT-p,p' elevated due to matrix interference. Quality control failure(s) observed.

EPA 8270D: MDLs are elevated due to sample dilution. MS accuracy for Atrazine could not be assessed due to high content of the analyte in the spiked sample.

Ref. Method and Comment:

EPA 200.8 Rev. 5.4: The lead matrix spike recovery data for one of two spiked samples is unavailable due to high analyte concentration in the QC sample. The lead result was confirmed in the undigested sample on 01/30/2015.

SM 2540 D-97: The PQL was elevated due to sample matrix interference.

DEP SOP: GC-011-5 (based on EPA 608 and 617): Quality control failure(s) observed.

EPA 8270D: Quality control failure(s) observed.
