Mechanisms for Rapid Response to Environmental Statistics Problems

Research Project

Under a cooperative agreement with the EPA, NISS provided the EPA rapid access to the national statistics community, which in turn furnished statistical input and commentary on environmental issues in a timely basis to policy and decision makers, other officials and researchers. This project provided rapid, accurate, and informed responses by statistical experts to inquiries about issues important to the EPA.
