Survey the Jukskei River bank condition in Alexandra from a safe vantage

The Jukskei River running through Alexandra is one of the most degraded urban rivers in South Africa, carrying heavy contamination and flooding fast after rain. A survey from the public path above the bank builds a current photo record without any water contact. Standard: UNEP freshwater ecosystem health guidance; SDG 6.6 Proof: photo survey log of the river bank Method (UNEP freshwater ecosystem health guidance; SDG 6.6): 1. Walk the public path above the river bank. 2. Photograph each eroded or degraded stretch from the path. 3. Note visible erosion, dumping, or vegetation loss for each stretch. 4. Record the GPS point and date for every photo. 5. Submit the survey log with photos attached. Done when: photo survey log of the river bank

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.
