Water touches almost every aspect of American life: from food to electricity to consumer products. Understanding how we use water is crucial for learning how to be more responsible with water resources. For the first time, the U.S. Geological Survey is displaying the national compilation of water use data for every U.S. county. Explore the variety of water use across the U.S. to understand how we use our current resources.
Water use data has been collected and compiled by the USGS since 1950. This data has changed over time in terms of how it was categorized and at what spatial scale it was summarized to. This visualization shows that change over time as this dataset has become more powerful, and attempts to illustrate where the data can go in the future to be a more useful dataset going forward.
Microplastics, plastic particles less than 5 millimeters in diameter, are a contaminant of emerging concern in aquatic environments. Microplastics come from a wide range of potential sources (see Microplastics Sources sidebar), and are commonly grouped by size, as well as by particle types including fibers/lines, pellets/beads, foams, films, and fragments.
