Install a certified water filter at a Lamont community site that asks for one

Until the regional arsenic fix reaches every tap, an NSF/ANSI-53-certified point-of-use filter at a community center, church hall, or clinic waiting room is the honest interim: safe water where people actually gather, installed and documented so the next person can maintain it. Standard: NSF/ANSI 53 (arsenic reduction claims); CA SWRCB SAFER interim-solution guidance. SDG 6. Proof: before/after photos + certification mark + dated install label Method (NSF/ANSI 53 (arsenic reduction claims); CA SWRCB SAFER interim-solution guidance. SDG 6.): 1. Confirm the host site's invitation and pick the highest-use faucet with the site manager. 2. Verify the filter unit carries an NSF/ANSI 53 certification for the contaminant of local concern; photograph the certification mark. 3. Install per manufacturer instructions on the cold line; flush the cartridge for the full specified time. 4. Photograph the finished install, label it with the install date and cartridge model, and leave the manual with the site manager. Done when: before/after photos + certification mark + dated install 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.

Proof

before/after photos + certification mark + dated install label

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.
