Aldicarb is a toxic pesticide used on crops that can leach into groundwater. It affects the nervous system and is harmful to humans and animals if ingested.

Aldicarb is a carbamate pesticide primarily used on cotton and potato crops. It can easily leach into groundwater due to its high solubility. The EPA has set a maximum contaminant level of 3 parts per billion in drinking water. Aldicarb has been banned in many countries due to its toxicity. Exposure can cause nausea, dizziness, and respiratory difficulties. Water treatment plants use activated carbon filtration to remove aldicarb, but private well owners should test their water regularly if they live in agricultural areas where it's used.
