Log the condition of a public water tap in Imbaba (2026-07-20)

Imbaba is one of Cairo's densest informal districts, and public and building-entry taps often run cloudy, low-pressure, or not at all for stretches — a simple weekly condition log gives residents and the municipal program a clear record of which taps need attention before anyone spends money on a fix. Standard: WHO Guidelines for Drinking-water Quality — SDG 6.1 (Safe and Affordable Drinking Water). Proof: Timestamped photo of the tap and running water plus the condition note. Method (WHO Guidelines for Drinking-water Quality — SDG 6.1 (Safe and Affordable Drinking Water).): 1. Locate one public or building-entry tap. 2. Turn it on and observe flow, pressure, and clarity for one minute. 3. Photograph the tap and the running water. 4. Note flow/clarity/pressure in the log. 5. Repeat at the same tap on your next visit. Done when: Timestamped photo of the tap and running water plus the condition note.

$140 proposed

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.

Proof

Timestamped photo of the tap and running water plus the condition note.

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. 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.
