The Hydrologic Systems Team (HST) provides technical support and spatial analysis for the USGS National Water Quality Assessment (NAWQA) Program. One of the important roles of the HST in NAWQA is to help develop datasets, models, and decision-support tools to forecast the effects of changes in climate and land use on water quality in streams and aquifers. The HST works closely with the USGS Center for Integrated Data Analytics (CIDA) and with EROS Data Center to complete these tasks. These pages are intended for a place to house and distribute spatial datasets created and used within the NAWQA program.
