Install a certified water filter at an invited San Luis home

Where a San Luis tap test shows taste, sediment, or quality issues — or a family simply wants certainty — a certified under-sink or faucet filter ends the bottled-water treadmill. One installation typically saves a border household hundreds of dollars a year and a mountain of plastic. Standard: NSF/ANSI 42 and 53 certified filtration; EPA drinking water guidance; SDG 6. Proof: Installed filter photo + dry joints + flush photo Method (NSF/ANSI 42 and 53 certified filtration; EPA drinking water guidance; SDG 6.): 1. Confirm the invitation and review the tap test result to size the right certified filter. 2. Shut off the cold supply and install the under-sink or faucet-mount filter per manufacturer instructions. 3. Flush the new cartridge per instructions and check every joint dry. 4. Show the household the cartridge-change schedule and leave the manual. 5. Photograph the installed filter and first clean flush with date and GPS. Done when: Installed filter photo + dry joints + flush photo

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.
