Assessment of Per- and Polyfluoroalkyl Substances in Water Resources of New Mexico

Per- and polyfluoroalkyl substances (PFAS) are widespread anthropogenic chemicals that have been in use for the past 70 years. This class of compounds comprises thousands of chemicals including perfluorosulfonates (PFSAs) such as perfluorooctane sulfonate (PFOS), perfluorocarboxylic acids (PFCAs), and perfluorooctanoic acid (PFOA). As the use of these chemicals has grown so has their ubiquity in...

Streamflow response to potential changes in climate in the Upper Rio Grande Basin

The Rio Grande is a vital water source for Colorado, New Mexico, Texas and northern Mexico. A model was developed to determine how Rio Grande streamflow could change in the future. Both streamflow timing and volume displayed substantial potential changes. However, streamflow timing was most affected, and runoff could arrive a month earlier than the historic average if temperatures continue to warm...

Simulation of Pre- and Post-Fire Streamflow in the Upper Rio Hondo Basin, NM

The 2012 Little Bear Fire burned 44,000 acres in the upper Rio Hondo Basin in south-central New Mexico. Landscape in the Basin ranges from mixed conifer forests at higher elevations (12,000 ft) to desert shrubland at lower (5,200 ft) elevations. Burned areas are at risk of substantial post-wildfire erosion and flash floods. USGS post-wildfire analysis estimated 70% of the burned area had a high...

USGS Data Collection: Real-Time Rain Gages for Post Conchas-Fire Flood-Early Warning System

The Las Conchas fire started on June 26, 2011, near the small community of Las Conchas in the Jemez Mountains of north-central New Mexico. When the fire was contained on August 3, 2011, it had burned 156,593 acres of mixed conifer, pinyon/juniper, and ponderosa forest. At the time, it was the largest wildfire in New Mexico history. Peak burn severity was extreme; over 60,000 acres of the total...

Upper Rio Grande Basin Focus Area Study

The Upper Rio Grande Basin (URGB) of Colorado, New Mexico, Texas, and northern Mexico was chosen as a focus area study (FAS) for the USGS National Water Census. The conjunctive use of water in the URGB takes place under a myriad of legal constraints including the Rio Grande Compact agreement between the States, an international treaty with Mexico, and several federal water projects. Development of...

Hydrologic Studies in the East Mountain Area of Bernalillo County, NM

Recent expansion of suburban development and population growth in the Sandia Mountains of eastern Bernalillo County, NM (East Mountain Area, EMA), has led to increased residential and commercial construction and increased demands on available water resources. Information about the spatial and temporal variability of water resources is needed for continued population and economic growth. USGS...

Chemical Modeling of Acid Waters Questa Baseline and Pre-Mining Ground-Water Quality Investigation, Red River Valley Basin, New Mexico

The US Geological Survey and the New Mexico Environment Department entered into a Joint Powers Agreement as of April 30, 2001 to execute an investigation of baseline and pre-mining ground-water quality in the Red River Basin, New Mexico. The main objective is to infer the pre-mining ground-water quality at the Questa Molycorp mine site. This study was formulated because New Mexico law states that...
