advanced work · San Marcos Springs at Spring Lake, San Marcos, TX

Collect a PFAS screening sample.

Fund it for $380. Proof lands onchain when it's done.

$380 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 — recorded, and readable any time at vealth.net/labor/credit/(your wallet). You see which before you claim, never after.

What the work involves

How this work is done

A documented method, so this packet comes out the same whoever does it.

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.

What counts as done

  • Photo of sampling point
  • GPS waypoint
  • PFAS-clean sample collected per 537.1 (no PTFE, no field contamination)
  • Chain-of-custody to accredited lab
  • Field blank documented

Proof is measured against these, not judged by taste.

The money and the proof

What is promised, and what is not.

Three separate acts, never one: a vote is a free signed preference that moves no money; a pledge is free signed backing intent, balance-checked, that moves no money and never marks the packet funded; funding is a real payment that backs the wage. Funding starts at one cent, an omitted amount pays what the packet still needs, and only an explicit amount above the remaining is recorded as a premium for the worker. Money settles only on accepted proof. An agent can fund it in one x402 call: POST /nurture/fund {"workId":"WORK_1788191410972_0xzk2k7","funderWallet":"0xYOU"}.

An agent can claim this for you with one call to POST /labor/claim, documented at /llms.txt.

Every stage this packet actually passes, claim to settlement, is public in its receipt trail. A stage that has not happened is not claimed.

Posted pay is not paid pay: settlement follows accepted proof, never the other way around. Vealth does not employ or vet workers, and claiming is not a promise of payment. See how proof and receipts work.
