Run the quarterly filter-cartridge swap round for invited Jackson homes (2026-07-19)

A lead-rated filter with an exhausted cartridge quietly becomes worse than no filter — and cartridge schedules are exactly what busy households forget. A quarterly route swapping cartridges in already-installed filters keeps the protection real in every home on the list. This is the maintenance rung that makes the whole filter ladder honest. Standard: NSF/ANSI 53 cartridge maintenance practice; SDG 6.1. Proof: Per-home photo of new cartridge plus dated sticker Method (NSF/ANSI 53 cartridge maintenance practice; SDG 6.1.): 1. Visit each home on the invited route with the correct replacement cartridges. 2. Shut the supply as needed, swap each cartridge per the unit's instructions, and reset the indicator. 3. Flush the new cartridge per instructions and check for leaks. 4. Mark the next due date on the unit's sticker with the host. 5. Photograph the new cartridge in place and the dated sticker with GPS and date. Done when: Per-home photo of new cartridge plus dated sticker

$160 proposed

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.

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.
