Field notes
The homepage divides the 1,449 qualifying counties into five trend bands: 169 fast declines, 165 typical declines, 160 slow declines, 602 stable, and 353 rising. Its results draw on monitoring-well records rather than surveys of every private well; the site says those locations reflect decades of state and federal programs, leaving geographic coverage uneven.
