Check the flooded park soil near Minot, ND for contamination after high water (2026-07-07)

High water on the Souris River floodplain near Minot, ND leaves fresh sediment behind that can carry metals from upstream. Before kids play there again, a depth and metals check tells the parks department if it's clean. Standard: FEMA floodplain + EPA sediment screening; SDG 11.5 Proof: photo + GPS + deposition depth + metals screen Method (FEMA floodplain + green-infrastructure siting screen, ~45-90 min): 1. Confirm post-event conditions are safe; navigate to the site; record GPS. 2. Photograph deposited sediment / affected area. 3. Measure deposition depth at representative points. 4. If a sediment contaminant screen is in scope, run the metals field kit and record values. 5. Note debris, hazards, and the extent (sketch). 6. Enter depth, any analytes, hazard notes, GPS, photos into the proof record; sign. Equipment: GPS phone, tape/ruler for deposition depth, metals field kit (if sediment screen in scope), boots + gloves, camera Done when: Deposition depth recorded at representative points; Metals screen recorded (if in scope); Debris/hazard note + extent sketch; GPS waypoint + timestamped photos

Pay

$80 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

photo + GPS + deposition depth + metals screen

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: FEMA floodplain + green-infrastructure siting screen

Bring

• GPS phone
• tape/ruler for deposition depth
• metals field kit (if sediment screen in scope)
• boots + gloves
• camera

Steps

1. 1. Confirm post-event conditions are safe; navigate to the site; record GPS.
2. 2. Photograph deposited sediment / affected area.
3. 3. Measure deposition depth at representative points.
4. 4. If a sediment contaminant screen is in scope, run the metals field kit and record values.
5. 5. Note debris, hazards, and the extent (sketch).
6. 6. Enter depth, any analytes, hazard notes, GPS, photos into the proof record; sign.

If it does not match the plan

• Unstable ground / submerged debris / contaminated water -> document from safe footing; do not enter.
• Elevated metals in deposited sediment -> flag before any reuse; recommend lab confirm.

What counts as done

• Deposition depth recorded at representative points
• Metals screen recorded (if in scope)
• Debris/hazard note + extent sketch
• GPS waypoint + timestamped photos

Proof is measured against these, not judged by taste.
