Record the bare-soil play areas of invited Santa Ana yards for the lead program

Research in Santa Ana's older neighborhoods has mapped elevated lead in yard soils, concentrated where children play on bare dirt near old painted walls and busy roads. A photographed survey of invited yards — bare patches, play areas, drip lines, no digging or sampling — documents which households should be first in line for the county's testing and covering programs. Standard: EPA lead-in-soil screening guidance and county healthy-homes intake — SDG 3. Proof: Yard photo record with sketch Method (EPA lead-in-soil screening guidance and county healthy-homes intake — SDG 3.): 1. Confirm the occupant's invitation and walk the yard without disturbing soil. 2. Photograph bare-soil areas, play spaces, and building drip lines from standing height. 3. Sketch the yard noting where children spend time relative to bare soil. 4. Deliver the record to the occupant with program referral info and upload with GPS and date. Done when: Yard photo record with sketch

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.
