Keep Del Rey home water filters fresh with the monthly cartridge round (2026-07-19)

Small water systems and private wells in the fruit belt around Del Rey have a history of nitrate and legacy-chemical detections, and households that installed certified filters only stay protected while cartridges are changed on schedule. A monthly round keeps every filter on its dates. Standard: State Water Board SAFER drinking-water program; SDG 6 Clean Water and Sanitation. Proof: Photo of each new cartridge seated plus the dated tag Method (State Water Board SAFER drinking-water program; SDG 6 Clean Water and Sanitation.): 1. Confirm with each invited household which certified filter unit is installed and which cartridge it takes. 2. Shut the feed valve, swap the cartridge per the unit's instructions, and flush per the cartridge label. 3. Check for drips and write the swap date on the unit's tag. 4. Bag the spent cartridge for the trash and confirm the next swap date with the household. 5. Photograph the new cartridge seated and the dated tag, with GPS. Done when: Photo of each new cartridge seated plus the dated tag

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.
