Aldicarb Sulfone is a toxic breakdown product of the pesticide aldicarb. It can contaminate groundwater from agricultural runoff and affects the nervous system.

Aldicarb Sulfone forms when the pesticide aldicarb breaks down in the environment. It persists longer than aldicarb itself, allowing it to leach into groundwater from agricultural areas. The EPA measures this contaminant in parts per billion (ppb) and has established a Maximum Contaminant Level to protect public health. While specific health effects are complex, the primary concern is its potential impact on the nervous system. Regular testing of water sources helps monitor and control its presence in drinking water.
