Run a nitrate-focused tap test at an invited home in Cutler, Orosi, or East Orosi (2026-07-18)

East Orosi's small water system is one of California's best-documented failing systems — nitrate from decades of surrounding agriculture has repeatedly pushed its wells past safe limits, and the state's SAFER program lists the community for consolidation. Families here have hauled bottled water for years. A recorded tap test at each invited home keeps the household's own number current, because nitrate is invisible, tasteless, and hardest on infants. Standard: EPA nitrate MCL (10 mg/L as N) + California SAFER failing-system list; SDG 6 Clean Water and Sanitation. Proof: Photo of developed kit with legible nitrate result plus written readings with GPS/date Method (EPA nitrate MCL (10 mg/L as N) + California SAFER failing-system list; SDG 6 Clean Water and Sanitation.): 1. Bring a certified home test kit with a nitrate range that covers the 10 mg/L limit clearly. 2. Run the cold kitchen tap for two minutes and collect the sample per the kit instructions. 3. Develop and read the nitrate result carefully against the chart, plus the kit's other measures. 4. Record results and date, and explain plainly what the nitrate number means — especially for infant formula. 5. Photograph the developed kit at the tap and record the readings with GPS and date. Done when: Photo of developed kit with legible nitrate result plus written readings with GPS/date

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. You see which before you claim, never after.

How this work is done

A documented method, so this packet comes out the same whoever does it. Typically 30–60 minutes. Method of record: EPA drinking-water sampling (3Ts / LCR first-draw where lead is in scope)

Bring

• GPS-capable phone
• test kit for each named analyte (nitrate/coliform/arsenic/lead as specified)
• clean sample bottle + label
• nitrile gloves
• camera

Steps

1. 1. Navigate to the sampling point; confirm GPS is inside the posting radius; record the waypoint.
2. 2. Photograph the tap or wellhead with a legible timestamp.
3. 3. If first-draw is required, sample after >=6h stagnation; if flushed, run the tap 2-3 minutes first, then sample.
4. 4. Fill the bottle without touching the inside; cap immediately.
5. 5. Run each test per kit instructions; wait the exact develop/incubation time; read and record every value with units.
6. 6. Record coliform as present/absent after the stated incubation window.
7. 7. Enter all readings, units, GPS, time, and photos into the proof record; sign it.

If it does not match the plan

• Nitrate > 10 mg/L -> tag 'exceeds EPA MCL'; advise no infant consumption pending certified-lab confirmation.
• Total coliform present -> advise disinfection + retest; recommend lab confirmation.
• Arsenic > 10 ppb or Lead > 15 ppb -> tag exceedance; recommend certified-lab confirmation before any consumption guidance.

What counts as done

• GPS waypoint recorded inside the posting radius
• Timestamped photo of the exact sampling point
• Each required analyte recorded with a numeric value + units (or present/absent)
• Sampling type (first-draw vs flushed) explicitly noted

Proof is measured against these, not judged by taste.
