Log a litter transect along the Canal do Cunha fenceline.

The Canal do Cunha, which runs along Complexo da Maré toward Guanabara Bay, is a well-documented, heavily polluted urban waterway that carries contaminated runoff from across the city. Before any cleanup effort can be planned, a stand-off litter transect logged from the public embankment builds a real record of what's accumulating. This round never approaches or touches the canal water itself.

Pay

$140 proposed

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash — recorded, and readable any time at vealth.net/labor/credit/(your wallet). You see which before you claim, never after.

How this work is done

A documented method, so this packet comes out the same whoever does it.

Steps

1. Walk a fixed embankment line and note the transect start and end points.
2. Photograph visible trash accumulation in the canal from the embankment, at a safe stand-off distance.
3. Log an approximate count and type of debris visible.
4. Note the water's visible condition that day.
5. Submit the transect log with photos attached.

What counts as done

• Photos of debris accumulation from the embankment vantage
• GPS-tagged transect start and end points
• Written debris count and type note

Proof is measured against these, not judged by taste.

The standard this serves

Watershed Health. A watershed is everything the land pours into a stream, and the stream keeps the record. The EPA's bioassessment method reads that record through the small creatures living in the gravel: mayflies and caddisflies mean clean water, only worms and midges mean trouble. Mastery looks like a person who can wade one riffle with a net and tell you how the whole valley is doing. That skill is built sample by sample. This packet is one of them: one site, one careful count, one entry in the long record of a stream.
