Photograph and record yard conditions near the old Stringfellow zone in Glen Avon — document only, never dig

Glen Avon lives downhill from the Stringfellow site, one of California's most notorious hazardous-waste legacies, and older residents still remember contaminated storm flows through the neighborhood. Households near the historic flow path deserve a current written-and-photographed record of yard conditions — bare-soil areas, drainage lines, dust sources — to inform agency follow-up. This work is strictly observational: the record is the product. Standard: US EPA Superfund community-involvement practice (Stringfellow site vicinity) — SDG 3, SDG 11. Proof: Standing-position photo set plus a plain-language written record Method (US EPA Superfund community-involvement practice (Stringfellow site vicinity) — SDG 3, SDG 11.): 1. Meet the invited resident and walk the yard boundary they show you. 2. Photograph bare-soil areas, drainage paths, dust sources, and any staining from a standing position. 3. Record where children play and where garden beds sit relative to drainage lines. 4. Write up the observations in plain language for the resident and the record. 5. Upload photos with GPS and date and file the written record. Done when: Standing-position photo set plus a plain-language written record

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 soil screening (composite surface sample, XRF/field kit)

Bring

• trowel or auger
• clean bucket + mixing tool
• XRF analyzer or metals test kit
• PID for volatiles (if petroleum in scope)
• sample bags + labels
• N95 dust mask
• gloves + eye protection
• GPS phone
• camera

Steps

1. 1. Navigate to the parcel; record GPS; sketch a >=5-point sampling grid.
2. 2. Photograph each sampling point and any visible staining/fill/slag.
3. 3. Collect 0-15 cm cores from >=5 points; combine and mix in the clean bucket; subsample.
4. 4. Run XRF/test kit on the composite; record each metal in ppm.
5. 5. If petroleum is in scope, log PID readings and any odor/staining.
6. 6. Bag/label any lab subsample; complete chain-of-custody.
7. 7. Enter all analytes with units, depth, GPS, photos, and site sketch into the proof record; sign.

If it does not match the plan

• Lead > 400 ppm (residential) -> tag exceedance; advise raised beds / produce-washing / cover; recommend lab confirm.
• Arsenic > site screening level or PID indicating volatiles -> tag; recommend certified-lab confirmation before reuse.
• Suspected asbestos-containing material -> do not disturb; flag and stop.

What counts as done

• >=5-point composite collected at 0-15 cm
• Each screened metal recorded in ppm
• Visible staining/fill/slag noted (or absence)
• GPS waypoint + point photos + grid sketch

Proof is measured against these, not judged by taste.
