Document surface conditions along the public boundary of Butte's historic mining legacy area (2026-07-20)

Parts of Butte sit next to the historic mining legacy area, where fencing, signage, and ground condition need a plain public record for the responsible agency to track over time. This is document only, observed from the public street and sidewalk outside the fence line, never entering or touching the legacy ground. Standard: EPA Superfund and state voluntary cleanup program, document-only public observation Proof: Photos taken from the public vantage point plus a written observation log sent to the responsible agency. Method (EPA Superfund and state voluntary cleanup program, document-only public observation): 1. Stand only on the public sidewalk, street, or road shoulder outside any fencing or posted boundary. 2. Photograph the visible ground surface, signage, and fencing condition from that public vantage point only. 3. Do not touch, enter, or collect any sample of soil, dust, or water at the site. 4. Log the date, location, and what was visually observed in plain language. 5. Send the log and photos to the responsible public agency contact for the site. Done when: Photos taken from the public vantage point plus a written observation log sent to the responsible agency.

$190 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

Photos taken from the public vantage point plus a written observation log sent to the responsible agency.

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.
