Test the tap water at invited San Luis homes with certified kits

San Luis is a fast-growing border city where many households distrust their tap water and spend heavily on bottled water without knowing whether they need to. Certified home tap test kits, run correctly and logged, give each invited family a real answer — and build the block-level picture of where problems actually are. Standard: EPA Safe Drinking Water Act consumer testing guidance; SDG 6. Proof: Kit result photo + logged values per home Method (EPA Safe Drinking Water Act consumer testing guidance; SDG 6.): 1. Confirm the invitation and explain what the certified kit tests for. 2. Flush the tap as the kit directs, then collect the sample exactly per instructions. 3. Run or package the test per the kit's process and record the result values. 4. Explain the result to the household in plain language and leave the written copy. 5. Photograph the kit result and log it with date and GPS. Done when: Kit result photo + logged values per home

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

Kit result photo + logged values per home

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.
