However, the chlorine level necessary to control cross-contamination is not defined because there is no standard metric to measure cross-contamination. The idea that cross-contamination should not be detectable is an untenable standard. With most-probable-number procedures and other techniques, detection limits are quite fluid.
There are three candidate approaches for verify
