Quality Control Check Evaluation Flag Samples Affected<br />
Breakdown check (DDT)<br />
(SW8080A)<br />
Breakdown check (Endrin)<br />
(SW8080A)<br />
% Breakdown for DDT > 20% J positive DDT, DDE, <strong>and</strong> DDE<br />
results<br />
R non-detects for DDT if DDD <strong>and</strong><br />
DDE are positive<br />
%Breakdown for Endrin > 20% J positive endrin, endrin aldehyde,<br />
<strong>and</strong> endrin ketone results<br />
R non-detects for endrin if endrin<br />
aldehyde <strong>and</strong> endrin ketone are<br />
positive<br />

a/ MS/MSD = Matrix spike/matrix spike duplicate. k/ RPD = Relative percent difference.<br />
b/ NFG = National Functional Guidelines. l/ Common lab contaminants: methylene chloride, acetone, 2-butanone, <strong>and</strong> phthalates.<br />
e/ GC/MS = Gas chromatograph/mass spectroscopy m/ %R = Percent recovery.<br />
