Recommended for targeted testing for imidacloprid in drinking water. Imidacloprid is the most widely used insecticide in the world. It is an insect neurotoxin in the class of compounds known as neonicotinoids and is a suggested culprit for colony collapse disorder among honey bees. While only rated "moderately toxic" among mammals, imidacloprid boasts high solubility in water and long term persistence in the environment. Therefore, the US EPA considers imidacloprid a likely surface water and potential groundwater contaminant.
