Collect a compliance nitrate water sample, round 2 -- the Yettem community water system, Yettem, CA 93670.

The risk survey confirmed this SAFER-priority system needs current nitrate compliance data against the Title 22 MCL of 10 mg/L as N; a properly chain-of-custody-documented sample submitted to a certified lab keeps the community's compliance record current and flags any worsening trend.

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

before photos + chain-of-custody record + lab submission receipt + result reference + GPS

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.

Bring

• flow-rate measurement bag + timer
• toilet dye tablets
• moisture meter
• GPS / address
• camera
• tablet / data sheet

Steps

1. 1. Confirm the address; get a staff escort; photograph each fixture group.
2. 2. Measure flow rate at each faucet/shower with the bag-and-timer method; record gallons per minute (gpm).
3. 3. Test each toilet for leaks with a dye tablet (wait 10 min, check for color in the bowl); record flush volume.
4. 4. Inspect fixtures, meters, and irrigation for visible leaks/drips; note each.
5. 5. Read the water meter with all fixtures off; note any movement (indicates a hidden leak).
6. 6. Rank WaterSense fixture upgrades + leak repairs by estimated water/cost savings.
7. 7. Record flow rates, leak results, meter check, ranked measures, and photos into the proof record; sign.

What counts as done

• Photo of the sample point (tap or wellhead sampling port) before collection
• Chain-of-custody record for the sample (collector, date/time, sample ID)
• Certified-lab submission receipt
• Lab-result reference logged once returned, compared against the 10 mg/L as N MCL

Proof is measured against these, not judged by taste.

The standard this serves

Water Efficiency. Water efficiency is the quiet discipline of wasting nothing indoors. The EPA's WaterSense program sets the marks: how many gallons a minute a faucet should pass, how to find the leak that runs a toilet all night, how a household's water bill tells a story. Mastery looks like an auditor who can walk a home in an hour and find every hidden gallon. The skill is built one fixture at a time, which is exactly what this packet asks: measure one flow, find one leak, record one truth about where the water goes.
