Clear litter from the paved canal-edge walkway near Barrio Obrero (2026-07-20)

The paved walkway along the Cano Martin Pena canal collects blown litter and dumped trash on the land side, though the canal water itself is off limits to hands-on work. Clearing the walkway and bank keeps that litter from ever reaching the water. Standard: SDG 6, Clean Water and Sanitation, land-side litter prevention Proof: Before/after photos show the walkway cleared of litter Method (SDG 6, Clean Water and Sanitation, land-side litter prevention): 1. Stay on the paved walkway and land side; do not enter or wade into the canal 2. Walk the walkway and collect visible litter into bags 3. Sort recyclable material from general trash 4. Bag and stage collected debris for pickup 5. Photograph the cleared walkway section Done when: Before/after photos show the walkway cleared of litter

$180 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.

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.
