Protect a shared community well head serving a La Pintana campamento

Once individual households already run point-of-use filters, the deeper fix for a La Pintana campamento relying on a shared well is protecting the well head itself from surface contamination — runoff, debris, and animals can all reach an unprotected opening. A simple sealed cap and drainage apron keeps the source cleaner before any household filter even sees the water. This is intermediate build work at a site the community has invited. Standard: WHO drinking-water source protection guidance; SDG 6 (Clean Water and Sanitation) Proof: Photo of the sealed, protected well head Method (WHO drinking-water source protection guidance; SDG 6 (Clean Water and Sanitation)): 1. Confirm the community invites the work and inspect the current well head condition. 2. Clear debris and vegetation from immediately around the opening. 3. Install or repair a sealed cap over the well opening. 4. Build a simple sloped apron around the base to direct surface runoff away. 5. Photograph the finished, sealed well head and record the work date. Done when: Photo of the sealed, protected well head

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.
