All of it: the words, the place, the proof
Test your private well in the San Joaquin Valley annually for coliform, E. coli, nitrate, TDS, and pH. The San Joaquin Valley carries more than half of California's community water systems with persistently contaminated tap water, and nitrate, mostly from agricultural land use, has been documented across the large majority of wells sampled valley-wide. The state's regional nitrate programs (the State Water Resources Control Board's Nitrate Project, the Central Valley Regional Water Board's CV-SALTS program) study and fund fixes at the community-system level. A private-well household here still needs its own annual certified-lab result, read against the same EPA nitrate standard, to know where its own well stands.
Fund it for $150. The receipt lands onchain once the proof is approved.
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. 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. 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. 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. Fill each bottle to its stated line, cap immediately, and label each with the parameter, date, and time.
- 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. 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. 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. 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
- Documented San Joaquin Valley agricultural nitrate context noted as regional stewardship framing, never treated as a substitute for this household's own lab result
- 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 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_1788116700019_vlb0fpl","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.
Other acts: vote, pledge, fund
