Featured Product: USGS Groundwater Model Data Releases

Did you know that all groundwater models from new USGS publications released since October 1, 2016, are now available online for easy access and download? Making all USGS groundwater models available online:

• Supports USGS's obligation to fully share our data and interpretive products as part of the USGS public access plan and U.S. federal government open science and open data efforts.
• Serves model data sets from one location in a consistent format that can be easily located and downloaded by anyone with a computer, including State and Federal agencies, hydrology students, and consultants.
• Allows anyone with groundwater modeling experience to download the files, run the model, and make adjustments to evaluate possible future conditions.
• Provides a starting point to build upon for future model development by USGS, our Cooperators, and the public.

The USGS studies groundwater quality around the Nation. In this photo, USGS Hydrographer Jessica Anderson collects a water-chemistry sample from Pigeon Spring near Snake Gulch, Arizona, in February 2017. A recent USGS study found that uranium in Pigeon Spring was likely not related to nearby mining activity. The sampling was conducted as part of USGS studies to better understand the potential impacts of uranium mining activities on cultural, biological, and water resources near Grand Canyon National Park.
