Haloacetic acid analysis

Does anybody in here run EPA 552.2? I've been having a problem with internal standard recovery (1,2,3-trichloropropane). There seems to be some inconsistency in some of the samples. Are you familiar with any interferences that would affect an inconsistent internal standard recovery?(calculated by area). I haven't experienced this before.
I've looked at some of the newsgroups on Google, and couldn't find anything; I haven't found anything in the method either (hopefully I didn't skim right past it.)
Any suggestions would be appreciated. Thanks.
