USGS conducted a study of plastic pollution at this rural US site in the Midwest.  The recycler was receiving computers from companies at a rate which greatly exceeded the capacity of the operation.  Approximately 50,000 computers remained outdoors on 15 acres for nearly a decade.  The site has since been cleaned up.

On a hike one evening after classes at the National Resources Conservation Center at Shepherdstown, WV, I watched this sunset from the riverbank.

Paul Schuster, USGS, holding an ice core of Aufice (meaning over ice). Each layer represents a groundwater overflow event. Groundwater flows are predicted to increase with warming temperatures likely affecting the formation of Aufice in the Yukon River basin.

Example of wellhead plumbing typical of public wells sampled in a USGS study of 932 public wells nationwide. About 105 million people—or more than one-third of the Nation's population—receive their drinking water from one of the 140,000 public water systems across the United States that rely on groundwater pumped from public wells.
