Screen the water near the former AFFF training area in Riverton WY for PFAS (2026-07-10)

The former AFFF training area in Riverton WY is a plausible PFAS source with no recent screening of nearby water for PFOA/PFOS. Standard: EPA PFAS national primary drinking water regulation screening protocol Proof: photo of sampling point + GPS + PFAS field-strip or lab reading + chain-of-custody note Method (EPA Method 537.1 PFAS-clean sampling (lab analysis), ~45-90 min): 1. Before arrival, review the clean-hands/dirty-hands protocol; avoid fast food, cosmetics, and waterproof/Teflon gear that day. 2. Navigate to the point; record GPS; photograph the source. 3. Don powderless nitrile gloves; keep all fluoropolymer (PTFE/Teflon) away from the sample. 4. Collect the sample into the HDPE bottle per Method 537.1; do NOT rinse with sample water. 5. Collect a field blank alongside using the lab-provided water. 6. Cool immediately; complete the chain-of-custody; ship to the accredited lab within the hold time. 7. Record GPS, time, photos, blank, and COC number in the proof record; sign. Equipment: lab-provided HDPE (non-PTFE) bottles, powderless nitrile gloves, lab-provided field blank water, cooler + ice, GPS phone, camera, chain-of-custody form Done when: Clean-sampling protocol followed (no contamination sources present); Field blank collected alongside the sample; Chain-of-custody completed to an accredited lab within hold time; GPS waypoint + timestamped photo recorded

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 of sampling point + GPS + PFAS field-strip or lab reading + chain-of-custody note

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 Method 537.1 PFAS-clean sampling (lab analysis)

Bring

• lab-provided HDPE (non-PTFE) bottles
• powderless nitrile gloves
• lab-provided field blank water
• cooler + ice
• GPS phone
• camera
• chain-of-custody form

Steps

1. 1. Before arrival, review the clean-hands/dirty-hands protocol; avoid fast food, cosmetics, and waterproof/Teflon gear that day.
2. 2. Navigate to the point; record GPS; photograph the source.
3. 3. Don powderless nitrile gloves; keep all fluoropolymer (PTFE/Teflon) away from the sample.
4. 4. Collect the sample into the HDPE bottle per Method 537.1; do NOT rinse with sample water.
5. 5. Collect a field blank alongside using the lab-provided water.
6. 6. Cool immediately; complete the chain-of-custody; ship to the accredited lab within the hold time.
7. 7. Record GPS, time, photos, blank, and COC number in the proof record; sign.

If it does not match the plan

• PFAS is lab-analyzed, not read on-site -> mark result 'pending lab'.
• When the lab returns any analyte above the EPA health advisory -> tag exceedance and recommend point-of-use treatment guidance.

What counts as done

• Clean-sampling protocol followed (no contamination sources present)
• Field blank collected alongside the sample
• Chain-of-custody completed to an accredited lab within hold time
• GPS waypoint + timestamped photo recorded

Proof is measured against these, not judged by taste.
