Document bare-soil conditions near Commerce City's industrial edge — record only

Blocks near Commerce City's industrial corridor have legacy soil questions that families deserve answers to before kids play in bare yards. The entry rung is a careful record: where bare soil is exposed, where dust tracks from, what history neighbors report — documentation that helps credentialed programs target real testing. Standard: EPA/ATSDR soil-screening program context; SDG 3 and SDG 11. Proof: Yard photo set + sketch + notes with GPS Method (EPA/ATSDR soil-screening program context; SDG 3 and SDG 11.): 1. With the occupant's invitation, photograph bare-soil areas, play areas, and dust-track paths from the yard surface. 2. Record the home's distance and direction from the industrial edge and any resident history notes. 3. Map bare versus covered ground on a simple sketch. 4. Note wind-borne dust conditions observed. 5. File photos, sketch, and notes with date and GPS. Done when: Yard photo set + sketch + notes with GPS

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

Yard photo set + sketch + notes with GPS

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 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.
