| Subject: | [CPEO-MEF] Perchlorate |
[POSTED BY Seth Kirshenberg <Seth.Kirshenberg@KutakRock.com>] I have been told by scientists at labs that when measuring Perchlorate there are a number of interferences that tend to give false positives at 1 ppb using the EPA-approved method and hence it is extremely difficult to measure Perchlorate at 1 ppb and below accurately. What is the state of science and engineering on this issue? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
