This is the broad modern-chemistry panel: roughly 140 fungicides, insecticides, herbicides, and growth regulators screened by liquid chromatography-mass spectrometry, reported in parts per billion. It covers the compounds in current agricultural and residential use — neonicotinoids, strobilurin and triazole fungicides, carbamates, organophosphates, and modern herbicides. If you want to know whether the chemicals being applied in your watershed today are reaching your water, this is the panel that answers it. Method EPA 538. Full analyte list with individual detection and reporting limits is provided with your results.
