Water Science for Maryland, Delaware and the District of Columbia
National and Regional Assessments Team (NRAT)
Studies within the USGS Maryland-Delaware-DC Water Science Center are divided into teams. To find out more about the NRAT's current projects, publications, and capabilities, please visit the links in the left menu.
What is the National and Regional Asessments Team?
The goal of the National and Regional Assessments Team is to develop, direct, and maintain a viable, relevant, and innovative program of local, regional (multistate), and national hydrologic and water-quality science and assessments.
We aim to develop and provide innovative methods, techniques, and results that are relevant to the understanding and management of water resources. Although most studies are performed at large scales, the results of these projects address issues that are important across many different scales.
NRAT's study designs and assessments include the following:
NRAT supports federal programs of the USGS National Water Quality Assessment (NAWQA), Chesapeake Priority Ecosystem Study (PES), and U.S. Environmental Protection Agency (USEPA). These funds are often leveraged to contribute to the scope of local studies at the request of local partners to determine answers to similar questions at multiple scales.
