Keep the weekly overlook record of the Tijuana Estuary mouth conditions (2026-07-18)

The Tijuana Estuary is the largest intact coastal wetland in Southern California and the last stop for the river's contaminated flows before the ocean. A weekly photographed record from public overlooks — channel color, foam, sediment plumes, closure signage — tracks the crisis where it meets the sea, without anyone going near the water. Standard: Tijuana River National Estuarine Research Reserve monitoring context — SDG 6. Proof: Weekly overlook photo log Method (Tijuana River National Estuarine Research Reserve monitoring context — SDG 6.): 1. Visit the same public overlook points weekly at a consistent hour. 2. Photograph the estuary channels and mouth, capturing color, foam, and visible plumes. 3. Record odor, weather, and posted closure signs in the log. 4. Upload photos and the log with GPS and date. Done when: Weekly overlook photo log

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.
