Monitoring Pesticides in Water

Method detection limits and practical quantitation limits for pesticides, pesticide degradates, and selected target analytes, as of April 2009. Analyses for the listed compounds are performed by the Florida Department of Agriculture and Consumer Services (DACS) Laboratories. Values between the method detection limit and the practicial quantitation limit indicate that the compound was detected but there is some degree of uncertainty associated with the concentration.
