Log a litter transect along the Canal do Cunha fenceline in Maré

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. Standard: UNEP marine litter reduction guidance; SDG 14 (Life Below Water) Proof: Photo log of the litter transect from the embankment Method (UNEP marine litter reduction guidance; SDG 14 (Life Below Water)): 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. Done when: Photo log of the litter transect from the embankment

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. 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. Typically 30–60 minutes. Method of record: EPA dry-weather / AMD field screening

Bring

• GPS phone
• pH meter or strips
• conductivity meter
• ammonia + iron test kit as specified
• surfactant screen if specified
• gloves
• camera

Steps

1. 1. Navigate to the outfall/reach; record GPS; photograph it, capturing any visible flow or staining.
2. 2. Note whether flow is present in dry weather (yes/no).
3. 3. Measure and record pH, conductivity, and each specified analyte per kit instructions.
4. 4. Log any color, odor, floc, or aquatic-life observation.
5. 5. Enter all readings with units, GPS, time, and photos into the proof record; sign.

If it does not match the plan

• Dry-weather flow present with elevated conductivity/ammonia/surfactants -> flag suspected illicit discharge for the responsible agency.
• pH < 6 with visible iron floc -> tag suspected acid mine drainage; recommend metals lab panel.

What counts as done

• pH + conductivity recorded with units
• Each specified analyte recorded with a value
• Dry-weather flow present? recorded yes/no
• GPS waypoint + timestamped photo

Proof is measured against these, not judged by taste.
