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

Delano is a farmworker city of 50,000 in Kern County where municipal wells have needed treatment for legacy contaminants like 1,2,3-TCP, a fumigant chemical left over from decades of agriculture. Many families still buy bottled water because they do not trust the tap and have no recent reading of their own. A simple certified test kit, run at the kitchen tap and recorded, gives a household a real number instead of a rumor. Standard: EPA Safe Drinking Water Act limits + California SAFER drinking-water program; SDG 6 Clean Water and Sanitation. Proof: Photo of developed test kit at the tap plus recorded readings with GPS/date Method (EPA Safe Drinking Water Act limits + California SAFER drinking-water program; SDG 6 Clean Water and Sanitation.): 1. Bring a certified home drinking-water test kit (nitrate, lead, chlorine, hardness at minimum) to the host home at the agreed time. 2. Run the cold kitchen tap for two minutes, then collect the sample exactly as the kit instructions direct. 3. Develop the test strips or vials and read each result against the kit's chart in good light. 4. Write the results, date, and tap location on the kit card and explain to the host what each number means in plain words. 5. Photograph the completed test alongside the tap and record the results with GPS and date. Done when: Photo of developed test kit at the 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.
