USGS Water Mission Area Announces National Water Availability Publications
How Do We Improve Large-Scale Water-Quality Trends?
Large, multi-site trend studies are important for evaluating broad geographic changes in water-quality. However, considerable effort is needed to evaluate the site-specific models that make up these studies. Therefore, USGS scientists used over 6,000 trends models to design a semi-automated, time-saving method to streamline this process.

Water Use Estimates:
The USGS released water use estimates for 2000 through 2020 for the three largest categories of water use in the United States: thermoelectric power generation, irrigation, and public supply. The estimates are the result of the development of a modeling framework by the USGS in collaboration with other federal, state, local, and academic partners.
See the USGS Water Use Program for more information or contact USGS scientist Richard Niswonger.

Pesticides Likely Impacting Invertebrates in our Nation’s Streams:
The USGS studied pesticides transported by stormwater, surface runoff, and wastewater in over 400 streams. Scientists determined that four pesticides were likely toxic and impacting aquatic invertebrate communities at a regional scale in one or more of five regions studied.

About the USGS Water Mission Area
Water information is fundamental to national and local economic well-being, protection of life and property, and effective management of the Nation’s water resources. The USGS works with partners to monitor, assess, conduct targeted research, and deliver information on a wide range of water resources and conditions including streamflow, groundwater, water quality, and water use and availability.
