Collect a PFAS screening sample.

Collect a PFAS screening sample at San Marcos Springs at Spring Lake, San Marcos, TX. Springs and public water near San Marcos Springs at Spring Lake deserve a clean baseline check for the forever chemicals that show up across Texas water. These are the headwaters of the San Marcos River over the Edwards Aquifer. A contamination controlled sample is collected from a safe public vantage with a chain of custody to an accredited lab.

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

What it looks like

Pay

$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.

Proof

photo of sampling point + GPS + PFAS-clean sampling chain-of-custody to lab

This is exactly what gets it approved. Nothing settles without it.

The creator wallet. Its signature is what approves proof and settles the wage.

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_1790785265602_g52dmxh","funderWallet":"0xYOU"}.

Claiming is free. You sign to prove the wallet is yours: no card, no deposit, no fee. Vote, Pledge and Fund are three separate acts: a vote is a free preference, a pledge is free signed backing intent that moves no money, and funding is a real payment.

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.
