The Arkansas Water Well Construction Commission (AWWCC) was formed by the Arkansas General Assembly in 1969 to protect the general health, safety, and welfare of Arkansas by regulating water well construction and pump installation. The AWWCC's rules provide a framework for proper development of underground water in an efficient, orderly, sanitary, reasonable, and a safe manner. 

The Integrated Data and Tools Catalog is an online platform that allows modelers and researchers to explore and share datasets, tools and services, and use cases used by Water Resources Mission Area (WMA) projects to advance water science activities.

The Earth Observing Satellites Online Compendium contains details about past, present and future Earth observing satellites and the sensors they carry. This information compiled by staff at the USGS Earth Resources Observation and Science (EROS) Center in Sioux Falls, South Dakota.

Do we have your trails? The USGS Trail Data Portal allows land managers to submit their trail data for potential inclusion into the nationwide trails dataset. The dataset must have at least 50 miles of trails, be in the public domain, and pass a data review to be included. Email trails@usgs.gov for more information.

TRAILS – Trail Routing, Analysis, and Information Linkage System is a trail planning and collaboration tool that utilizes geospatial analysis to determine potential routes for new trail connections or to reroute an existing trail.  

The USGS Trails Explorer visualizes the current distribution of aggerated trails.  

The location of the freshwater–saltwater interface along the coast is an important factor in the ecological and socioeconomic dynamics of coastal communities. Salinity is a critical response variable that integrates hydrologic and coastal dynamics including sea level, tides, winds, precipitation, streamflow, and tropical storms.

The USGS developed the SPARROW (SPAtially Referenced Regressions On Watershed attributes) modeling framework to relate water-quality monitoring data to upstream nutrient and sediment sources and watershed characteristics. The mapper can be used to evaluate alternative hypotheses about the relative importance of various pollutant sources.

The U.S. Geological Survey (USGS) South Atlantic Water Science Center and the Environmental Protection Division of the Georgia Department of Natural Resources have been collecting and compiling water-use information in Georgia since 1980 as part of an ongoing cooperative agreement.

The Groundwater Conditions of Georgia web tool has interactive maps and graphs, that calculate water level trends over time. The application is a continuation of a series of reports begun in 1978.
