The polluter shows up in thermal

Unlicensed greywater and industrial runoff dumped into public waterways almost always carries a temperature differential from the receiving water. You don't need a lab to see it — a low-IR camera flown from a kite or tethered balloon images the plume directly. Public Lab and its decade-long community-mapping lineage have been proving this in watersheds around the world, at costs and cadences that state agencies can't match.

This isn't a gadget story. It's an accountability-infrastructure story. The instruments of environmental regulation don't have to sit inside the regulator's office. When a riverside neighborhood holds the cameras, the kite, and the workflow, the discharge shows up on a map that the community owns before the official complaint even gets filed.

What this lets stakeholders do: read the state of their own watershed and defend it with evidence gathered at human scale. Totem Protocol, Perceptagon, and ShurIQ each step into this: Perceptagon builds the sensing, Totem encodes the intent and the trail, ShurIQ publishes the observation against a rubric that names what the water *should* look like.

What's still open: how does community-gathered thermal evidence integrate with regulatory processes designed around state-agency instruments?
