Community ambient-air monitoring — Neighborhood near legacy textile-mill corridor, Greenville, SC

A Greenville neighborhood near a legacy textile-mill corridor has unmeasured ambient PM2.5. Standard: EPA NAAQS PM2.5 + community air-monitoring protocol; SDG 11.6 Proof: photo of monitor sites + GPS + PM2.5 log at 3 points + truck-traffic note Method (EPA NAAQS community ambient-air screening (PM2.5), ~45-90 min): 1. Choose >=3 points (near-source/roadside, mid, background); record GPS at each; stay off the roadway. 2. Photograph each monitoring location. 3. Log PM2.5 (ug/m3) at each point over a comparable peak period. 4. Record wind direction, time, and nearby source activity (e.g., truck traffic). 5. Compare readings to the NAAQS reference. 6. Enter the PM2.5 logs, wind/time, source note, GPS, photos into the proof record; sign. Equipment: calibrated PM2.5 monitor, GPS phone, wind/weather note source, hi-vis vest, camera Done when: PM2.5 logged at >=3 points (near-source / mid / background); Wind direction + time recorded; Source-activity observation recorded; GPS waypoints + location photos

$80 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

photo of monitor sites + GPS + PM2.5 log at 3 points + truck-traffic note

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

• 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.
