Method 508.1 is used to determine twenty-nine chlorinated
pesticides, three herbicides, and four organohalides in
ground water, drinking water, and water in any treatment
stage. The analytes are extracted from the water using a 47
mm C18 disk. The disk is extracted on the Horizon
Technology SPE-DEX® 4790 Automated Extraction
System using Ethyl Acetate and Methylene Chloride
(DCM). The extract is then dried and concentrated using
the Horizon Technology DryVap® with DryDisk®
technology. Final analysis is by GC/ECD.

The initial use of many chlorinated pesticides, herbicides, and organohalides were to aid humanity. DDT was created to control mosquito populations which significantly limited the number of malaria and typhus cases in World War II; while the use of Atrazine has increased the production of corn and sugar cane farms and helped to supply the world
with the food it so drastically needs.
