Log Imperial Beach's sewer-gas odor events street by street each week (2026-07-18)

Imperial Beach residents report odor events strong enough to close windows and cancel practice, and monitoring near the river valley has recorded hydrogen sulfide spikes. A weekly street-level odor log with times, strength, and wind builds the neighborhood's side of the public record. Standard: San Diego County APCD Tijuana River valley air monitoring — SDG 3. Proof: Weekly odor log with photos Method (San Diego County APCD Tijuana River valley air monitoring — SDG 3.): 1. Walk a fixed route of residential streets weekly and after strong events. 2. Score odor 0–5 with time, location, and wind direction per stop. 3. Photograph context from public space at each logged stop. 4. Upload the log and photos with GPS and date. Done when: Weekly odor log 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 45–90 minutes. Method of record: EPA NAAQS community ambient-air screening (PM2.5)

Bring

• calibrated PM2.5 monitor
• GPS phone
• wind/weather note source
• hi-vis vest
• camera

Steps

1. 1. Choose >=3 points (near-source/roadside, mid, background); record GPS at each; stay off the roadway.
2. 2. Photograph each monitoring location.
3. 3. Log PM2.5 (ug/m3) at each point over a comparable peak period.
4. 4. Record wind direction, time, and nearby source activity (e.g., truck traffic).
5. 5. Compare readings to the NAAQS reference.
6. 6. Enter the PM2.5 logs, wind/time, source note, GPS, photos into the proof record; sign.

If it does not match the plan

• Roadside work near heavy traffic -> stay off travel lanes; hi-vis at all times.
• Near-source PM2.5 well above background and NAAQS -> flag an environmental-justice exposure concern.

What counts as done

• PM2.5 logged at >=3 points (near-source / mid / background)
• Wind direction + time recorded
• Source-activity observation recorded
• GPS waypoints + location photos

Proof is measured against these, not judged by taste.
