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.
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.
MCL ADVISORY - ACTION IS HIGHLY RECOMMENDED
Oxamyl levels were detected in your water sample to exceed the maximum contaminant level (MCL).
ACTION IS OPTIONAL
Oxamyl levels were detected in your water sample but do not exceed the maximum contaminant level.
