Install a certified water filter at an invited Guadalupe home (2026-07-20)

Guadalupe's small municipal water system sits in a region of the Central Coast where nitrate contamination tied to decades of surrounding agriculture is a documented, ongoing concern for small ag-town systems. A certified point-of-use filter gives a household safer water at the kitchen tap today. Standard: US EPA Safe Drinking Water Act nitrate MCL; California SAFER program — SDG 6. Proof: Photo of the installed, leak-free filter and its certification label Method (US EPA Safe Drinking Water Act nitrate MCL; California SAFER program — SDG 6.): 1. Confirm the filter is NSF/ANSI-certified for nitrate reduction. 2. Shut off the water supply to the kitchen tap. 3. Install the filter housing and cartridge per manufacturer instructions. 4. Run water through the new filter and check for leaks. 5. Photograph the installed filter and certification label with GPS and date. Done when: Photo of the installed, leak-free filter and its certification label

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.
