Log odor and dust conditions from the public edge of the Zone 3 landfill

Guatemala City's Zone 3 municipal landfill sits beside long-established residential blocks, and the households nearest the fenceline live with odor and windborne dust that has never been formally logged from the public side of the boundary. A simple stand-off observation record — what's smelled, seen, and when — gives the municipal program a real basis to act. This stays strictly a public-vantage observation, never contact with the site itself. Standard: WHO ambient air quality guidance; SDG 11 (Sustainable Cities and Communities) Proof: Photo-and-note observation log from a public vantage Method (WHO ambient air quality guidance; SDG 11 (Sustainable Cities and Communities)): 1. Stand at a public street or fenceline vantage well clear of the landfill boundary. 2. Note the time, wind direction, and any odor or visible dust observed. 3. Photograph the fenceline and surrounding street from the public vantage. 4. Repeat the observation at a different time of day if possible. 5. Submit the observation log with photos and notes attached. Done when: Photo-and-note observation log from a public vantage

$140 proposed

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.
