Swap the filter cartridge on schedule at an invited Delano home (2026-07-18)

A water filter only protects a family while its cartridge is fresh; an expired cartridge quietly stops working. In Delano, homes that received point-of-use filters often skip the swap because the cartridge costs feel unclear and the steps are unfamiliar. A scheduled quarterly swap keeps the protection real. Standard: Manufacturer cartridge-life specification under NSF/ANSI 53 certification; SDG 6 Clean Water and Sanitation. Proof: Photo of old vs new cartridge plus dated housing with GPS/date Method (Manufacturer cartridge-life specification under NSF/ANSI 53 certification; SDG 6 Clean Water and Sanitation.): 1. Confirm the filter model with the host and bring the correct replacement cartridge. 2. Shut the supply valve, relieve pressure, and remove the spent cartridge without spilling. 3. Seat the new cartridge, restore supply, and flush per the manufacturer's instructions. 4. Write the swap date on the cartridge housing with a marker so the next date is obvious. 5. Photograph the old and new cartridges side by side and record the swap with GPS and date. Done when: Photo of old vs new cartridge plus dated housing with GPS/date

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.
