Install a certified lead-removing water filter in an invited Flint home

Flint's water crisis began in 2014 when the city's supply switch corroded lead pipes, and although service lines have largely been replaced, many households still depend on point-of-use filters because indoor plumbing is old and trust in the tap is still rebuilding. A correctly installed, lead-certified filter on the kitchen faucet is the simplest protection a family can have today. Standard: EPA Lead and Copper Rule + NSF/ANSI-53 lead-reduction filter certification; SDG 6 Clean Water and Sanitation. Proof: GPS-dated photos of the certified filter installed and flushed Method (EPA Lead and Copper Rule + NSF/ANSI-53 lead-reduction filter certification; SDG 6 Clean Water and Sanitation.): 1. Confirm the host's invitation and agree on an arrival time before entering the property. 2. Check the filter package for the NSF/ANSI-53 lead-reduction certification mark and note the model. 3. Install the filter on the kitchen faucet following the package instructions, hand-tight only. 4. Run the first-use flush for the full time the instructions require. 5. Write the install date on the cartridge with a marker so the swap date is obvious. 6. Photograph the installed filter, the certification mark, and the dated cartridge with GPS and date on. Done when: GPS-dated photos of the certified filter installed and flushed

$80 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.

Proof

GPS-dated photos of the certified filter installed and flushed

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.
