Dietary risk assessments performed by the US EPA during registration and review of pesticides include potential exposure from food and drinking water. An analysis was conducted to determine if there are any systemic issues making drinking water the driver for the dietary risk assessment during the registration process (sponsored by CropLife America). If erroneous exposure estimations from drinking water occupy a major portion of the dietary risk-cup (acute or chronic), it can prevent additional registration of new uses (including minor crops), and impact existing registrations, thereby stifling innovation. We randomly selected several risk assessments conducted by the EPA in the past ten years for new active ingredients, new uses, and registration reviews to determine if drinking water was the driver for the dietary risk assessment and, if so, what factors contributed to this outcome. For active ingredients under registration review, an analysis was conducted to determine if drinking water became a concern when the pesticide passed assessment during initial registration.
