Clear the litter from the shoreline at the Harlem River waterfront (2026-07-17)

Tide-stranded litter piles up along the accessible bank of the Harlem River waterfront faster than anyone clears it, working its way back out with every high tide. Standard: EPA NPDES MS4 stormwater program + watershed-health field protocol; SDG 6.6/14.1. Proof: before/after photos + sorted-litter photos + weight log + GPS Method (EPA NPDES MS4 stormwater program + watershed-health field protocol; SDG 6.6/14.1.): 1. Photograph the litter-strewn shoreline as found at low tide. 2. Work the accessible bank at low tide only, picking litter by hand or grabber tool without wading beyond ankle depth. 3. Sort recyclables from trash and bag both separately. 4. Photograph the cleared shoreline from the same vantage and log the weight/volume collected. Done when: before/after photos + sorted-litter photos + weight log + GPS

$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

before/after photos + sorted-litter photos + weight log + GPS

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 dry-weather / AMD field screening

Bring

• GPS phone
• pH meter or strips
• conductivity meter
• ammonia + iron test kit as specified
• surfactant screen if specified
• gloves
• camera

Steps

1. 1. Navigate to the outfall/reach; record GPS; photograph it, capturing any visible flow or staining.
2. 2. Note whether flow is present in dry weather (yes/no).
3. 3. Measure and record pH, conductivity, and each specified analyte per kit instructions.
4. 4. Log any color, odor, floc, or aquatic-life observation.
5. 5. Enter all readings with units, GPS, time, and photos into the proof record; sign.

If it does not match the plan

• Dry-weather flow present with elevated conductivity/ammonia/surfactants -> flag suspected illicit discharge for the responsible agency.
• pH < 6 with visible iron floc -> tag suspected acid mine drainage; recommend metals lab panel.

What counts as done

• pH + conductivity recorded with units
• Each specified analyte recorded with a value
• Dry-weather flow present? recorded yes/no
• GPS waypoint + timestamped photo

Proof is measured against these, not judged by taste.
