In samples from all other systems, any result for atrazine generated by Method AG-625 that is greater than one-half the maximum contaminant level (MCL) (in other words, greater than 0.0015mg/L or 1.5 |xg/L) must be confirmed using another approved method for this contaminant and should use additional volume of the original sample collected for compliance monitoring.
