The National Pollutant Discharge Elimination System (NPDES) is a permit program established as part of the Clean Water Act. Facilities dumping into a body of water are required to have a permit and to periodically submit discharge water reports. A "violation" on the map means a facility exceeded the limits in its own permit or failed to submit a report.
Some specifics:
Data comes from EPA's ICIS-NPDES bulk exports, synced every 2 weeks.
There's ~550k facilities registered nationally.
We built a detailed view showing each facility's violation history (allowed limit vs. actual amounts for each pollutant, by quarter)
The largest organizations are active all over the world, so their values should be excluded from any sort of local analysis. The area near DC, for example, shows billions in funding due to organizations such as the Nature Conservancy.
Curious to hear what y'all glean from this. Is there anything you'd like to see included in the map?
Speak for the Trees is an experimental project that explores how AI might support the Rights of Nature movement. If equipped with data about an ecosystem and capital to act, what actions might an agent take to support an ecosystem and its guardians?
