Log the condition of a Cova da Moura public water tap

Cova da Moura grew as a self-built neighborhood outside Lisbon's formal street grid, and while the city has extended pipes to most streets, a few shared standpipes and older household connections still run low-pressure or intermittent — a simple photographed check tells crews which taps need a real fix first. Standard: WHO Guidelines for Drinking-water Quality + SDG 6. Proof: Photo log plus flow/pressure note Method (WHO Guidelines for Drinking-water Quality + SDG 6.): 1. Locate the public or shared tap and photograph its overall condition. 2. Run the tap and note pressure and flow (strong/weak/intermittent). 3. Check for visible leaks, corrosion, or damage at the fitting. 4. Note the time of day and whether flow changes at different hours. 5. Log the findings with GPS pin and date. Done when: Photo log plus flow/pressure note

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

Photo log plus flow/pressure 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.
