All of it: the words, the place, the proof

Test a Reston-area private well annually for coliform, E. coli, nitrate, TDS, and pH. The USGS, whose own research this standard's '43 million' figure and contaminant framing are drawn from, runs its headquarters here. The well's water has no current annual lab test, so contamination that cannot be tasted, smelled or seen can go unnoticed.

Offer to pay $130. The receipt lands onchain once the proof is approved.

What it looks like
A homeowner near Reston fills a sample bottle from an outdoor spigot at the wellhead, then signs a chain-of-custody form before shipping the sealed kit to a certified lab.

This job is not funded yet, so this figure is a proposed price, not money held for the worker. 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
Five parameters tested: coliform, E. coli, nitrate, TDS, pH + Samples collected per lab protocol with signed chain of custody + Each result compared only to its published standard + No household safe or unsafe verdict written + Out-of-standard result routed per the iron law

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

Safety, read before you claim

Positive coliform or E coli routes to the local health department for boil-water direction. Nitrate above the EPA MCL with an infant or pregnant person is urgent: switch to alternative water now and call a clinician, never boil to reduce nitrate.

The full safety list for this job:

  • Sample collection and result reading is against published EPA and CDC standards only, and the certified laboratory is the measurement authority, never a household 'safe' verdict.
  • Boiling addresses microbial risk only, never nitrate, and boiling concentrates nitrate as water evaporates so it is never used to reduce nitrate.
  • Contact a clinician about methemoglobinemia, also called blue-baby syndrome, risk.
  • No result in this packet is ever read as 'the water is safe.'
  • This packet is independent of and not affiliated with USGS: named as the real, verified home of this standard's own key statistic and contaminant-research program, not an endorsement or partnership.
How this work is done

How this work is done

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

Bring

  • certified-lab sample bottles/kit for coliform, nitrate, TDS, and pH
  • nitrile gloves
  • cooler with ice if the lab requires cold shipping
  • chain-of-custody form
  • camera
  • GPS-capable phone

Steps

  1. 1. Select the sampling point closest to the well, before any treatment device (softener, filter) unless the lab's protocol specifies otherwise, and photograph it with GPS recorded.
  2. 2. Follow the certified lab's own bottle and kit instructions exactly for each parameter: total coliform bacteria, nitrate as N, total dissolved solids, and pH.
  3. 3. Don gloves before handling sample bottles and disinfect the tap per the lab's instructions before drawing the coliform sample, without touching the inside of the bottle or cap.
  4. 4. Fill each bottle to its stated line, cap immediately, and label each with the parameter, date, and time.
  5. 5. Complete and sign the chain-of-custody form, keep samples cool if the lab requires it, and ship or deliver to the certified laboratory within its stated hold time.
  6. 6. When results return, record all five values with units exactly as reported: total coliform (present/absent), E. coli if reflex-tested, nitrate as N in mg/L, TDS in mg/L or ppm, and pH.
  7. 7. Compare each result only to its own published standard, coliform/E. coli as presence-absence and nitrate against the EPA 10 mg/L MCL; never write a household 'safe' or 'unsafe' verdict for the whole water supply.
  8. 8. Route any out-of-standard result per the decision rules and record exactly where it was routed (local health department, alternative water source, clinician).

What counts as done

  • Certified laboratory named, with samples collected per its own kit/bottle instructions and a signed chain-of-custody form
  • All five parameters (total coliform, E. coli, nitrate as N, TDS, pH) reported with values and units
  • Each result compared explicitly to its published standard (coliform/E. coli presence-absence; nitrate vs the EPA 10 mg/L MCL); no household 'safe' or 'unsafe' verdict written
  • Any positive coliform/E. coli or nitrate exceedance routed per the decision rules, with the routing (local health department, alternative water, clinician) recorded

Proof is measured against these, not judged by taste.

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, made by the payer straight to the worker, with no Vealth fee. Paying Vealth is closed: Vealth takes no new card or wallet payment for a job. To fund a job, offer to pay the worker directly, then pay them yourself when you accept the proof, from your own wallet or by your own card or bank. From a wallet: prepare_token_offer, sign, submit_token_offer; after the proof is accepted you pay the worker on chain and the worker records it (prepare_token_settlement, or POST /labor/settle for USDC on Base). By card or bank: prepare_direct_offer, sign, submit_direct_offer; you pay the worker yourself and the worker records it with prepare_direct_settlement. Both are free, need no gas, and move no money through Vealth.

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.
