Record the monthly litter and debris transect along the river valley trail edge (2026-07-18)

Storm flows strand plastic, tires, and sediment banks through the Tijuana River Valley's trail corridors, and cleanup agencies prioritize by documented density. A monthly photographed transect from the dry public trail — counting debris types in fixed segments without touching anything — feeds that prioritization with real numbers. Standard: Tijuana River Valley cleanup prioritization and CWA trash policy monitoring — SDG 6. Proof: Segment tally sheet with photos Method (Tijuana River Valley cleanup prioritization and CWA trash policy monitoring — SDG 6.): 1. Walk the fixed trail transect segments on dry ground only. 2. Count and categorize visible debris per segment on the tally sheet without touching any item. 3. Photograph each segment's representative debris field. 4. Upload tallies and photos with GPS and date. Done when: Segment tally sheet with photos

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.
