Document litter and blockage conditions along the Khlong Toei canal bank (2026-07-18)

Khlong Toei, Bangkok's oldest and largest port-side slum, sits along a canal that carries heavy household and market waste and backs up onto lanes during rain. A regular photo record from the dry bank gives the community a case for a proper municipal clearing crew. Standard: UN-Habitat urban waterway management guidance; SDG 6.3 (improve water quality). Proof: Blockage-point photo log + severity notes Method (UN-Habitat urban waterway management guidance; SDG 6.3 (improve water quality).): 1. Walk the dry public bank path along the marked canal stretch. 2. Photograph each visible blockage or litter accumulation point. 3. Log the blockage locations and approximate severity. 4. Note any odor or visible discoloration without approaching the water. 5. Submit the photo set and log as the sweep record. Done when: Blockage-point photo log + severity notes

$80 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. You see which before you claim, never after.

Proof

Blockage-point photo log + severity notes

This is exactly what gets it approved. Nothing settles without it.

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.
