Run a home tap-water test kit at an invited McFarland home and record the result (2026-07-18)

McFarland is a small Kern County farm town whose water system has carried arsenic and legacy fumigant-chemical detections over the years, and whose families remember decades of health worry. Most households have never seen a current reading from their own tap. A certified home test kit, run and recorded, replaces fear with a number the family can act on. Standard: EPA Safe Drinking Water Act limits + California SAFER program; SDG 6 Clean Water and Sanitation. Proof: Photo of developed kit at tap plus recorded readings with GPS/date Method (EPA Safe Drinking Water Act limits + California SAFER program; SDG 6 Clean Water and Sanitation.): 1. Bring a certified home drinking-water test kit covering nitrate, arsenic-range screening, lead, and chlorine. 2. Run the cold kitchen tap for two minutes and collect the sample per the kit instructions. 3. Develop and read each result against the kit chart in good light. 4. Record results and date on the kit card and explain each number to the host in plain words. 5. Photograph the developed kit at the tap and record the readings with GPS and date. Done when: Photo of developed kit at tap plus recorded 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.
