Install a certified water filter in an invited East Chicago home

East Chicago's lead story is not only soil: aging service lines and indoor plumbing put lead in tap water in parts of the city during the same years the Superfund crisis unfolded. A certified filter at the kitchen tap of an invited home is immediate, cheap protection. Standard: EPA Lead and Copper Rule + NSF/ANSI-53 filter certification; SDG 6 Clean Water and Sanitation. Proof: GPS-dated photos of certified filter installed and flushed Method (EPA Lead and Copper Rule + NSF/ANSI-53 filter certification; SDG 6 Clean Water and Sanitation.): 1. Confirm the host's invitation. 2. Verify NSF/ANSI-53 certification on the filter packaging. 3. Install on the kitchen faucet per instructions, hand-tight only. 4. Run the required first-use flush and date the cartridge. 5. Photograph the installed filter, certification mark, and dated cartridge with GPS and date on. Done when: GPS-dated photos of 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 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.
