Walk the weekly Mon Valley air observation round in Braddock (2026-08-03)

Braddock lives beside the Edgar Thomson steel works, downwind of the Clairton coke plant, in the Mon Valley air basin that records some of the worst fine-particle days in the eastern United States. Dated street-level logs of odor, haze, and visible emissions from public ground are the community record that county air enforcement actions cite. Standard: Allegheny County Health Department air program + EPA community observation guidance; SDG 3 + SDG 11. Proof: Completed weekly log with GPS/time-stamped photos Method (Allegheny County Health Department air program + EPA community observation guidance; SDG 3 + SDG 11.): 1. Walk the fixed public route at the same hour weekly, covering the assigned observation points. 2. Record odor type and strength, visible haze or plumes, and any dust fallout at each point. 3. Photograph observations from public sidewalks with GPS and time. 4. Note wind direction and weather. 5. Submit the completed log and photos the same day. Done when: Filled log for every point with times; GPS-tagged photos of haze, plumes, or fallout; Wind and weather note; Same-day submission

Pay

$160 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.

Proof

Completed weekly log with GPS/time-stamped photos

This is exactly what gets it approved. Nothing settles without it.

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

• Filled log for every point with times
• GPS-tagged photos of haze, plumes, or fallout
• Wind and weather note
• Same-day submission

Proof is measured against these, not judged by taste.
