Log field chemical application drift risk from the public road, site 1 -- the Biola Community Services District corridor, 4925 N Seventh Street, Biola, CA 93606 (2026-07-23)

Homes along this westside corridor sit close to active farm fields with no standing public record of field chemical/fumigant application drift risk toward the residential edge, information the CA Department of Pesticide Regulation's buffer-zone/notification framework relies on for community context. Standard: CA DPR agricultural field-application buffer-zone/notification framework, community stand-off observation practice, document-only; SDG 3.9/11.6. Proof: document-only stand-off log (proximity, wind direction, visible application activity, photo) + GPS + timestamp 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

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

document-only stand-off log (proximity, wind direction, visible application activity, photo) + GPS + timestamp

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.
