Keep a weekly industrial-edge air diary from public sidewalks in South El Monte (2026-07-18)

South El Monte interleaves homes with hundreds of small metal, auto, and chrome shops, and residents smell solvent and grinding dust on different days with no record kept. A fixed-point weekly diary — odor type, dust films, sensor readings, wind — from public sidewalks builds the pattern the air district needs to target inspections. Standard: South Coast AQMD community air protection practice (AB 617); SDG 3 (Good Health and Well-being). Proof: Weekly diary sheet with fixed-point photos Method (South Coast AQMD community air protection practice (AB 617); SDG 3 (Good Health and Well-being).): 1. Observe from the same two public sidewalk points on the residential-industrial seam at the same hour weekly. 2. Note odor character and strength, visible dust or plumes, wind, and the nearest public sensor reading. 3. Complete one diary sheet per visit; file an AQMD complaint for strong events and log the number. 4. Track changes week over week. 5. Photograph the view from each point and the sheet with date and GPS. Done when: Weekly diary sheet with fixed-point 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.
