Oxamyl (Vydate)

GENERAL INFORMATION
Oxamyl, a synthetic organic chemical, is a highly toxic white crystalline solid with a slight sulfurous odor. Oxamyl is the chemical ingredient identified in widely used insecticides/nematicides, for example Vydate L. Vydate is a registered trademark of DuPont Inc. EPA has classified most products containing oxamyl as restricted use pesticides intended for occupational use only for control of insects, mites and nematodes on field crops, fruits and ornamentals. Major sources of oxamyl in drinking water are runoff and leachate from its use as an insecticide and leakage, poor storage, or improper disposal practices related to its use and manufacture.

HEALTH EFFECTS
Some people who drink water containing oxamyl well in excess of the maximum contaminant level (MCL) for many years could experience slight nervous system effects.

Treatment options: 

TREATMENT OPTIONS
Granular Activated Carbon (GAC) or Powdered Activated Carbon (PAC) are considered the best available technologies (BAT) for treatment of many organic contaminants including organic pesticides, volatile organic compound (VOCs), and Trihalomethanes (THMs) (by-products of chlorination). Treatment can be at the tap (called point of use or POU) or the entire house.
