Count the trash on fixed Coyote Creek trail segments in east San Jose, monthly (2026-07-18)

Coyote Creek through east San Jose flooded thousands of residents in 2017 and still runs past Mayfair carrying the city's trash load toward the bay — and cleanup effort here is spent blind, without segment data showing where litter actually enters. A fixed monthly count on three trail segments turns volunteer hours into targeted source control. Standard: Coastal cleanup transect data-card method applied to an urban creek; SDG 6 (Clean Water and Sanitation). Proof: Completed transect card with segment photos Method (Coastal cleanup transect data-card method applied to an urban creek; SDG 6 (Clean Water and Sanitation).): 1. Walk the same three 100-meter trail segments along the creek each month. 2. Count and categorize every visible litter item per segment without collecting. 3. Photograph each segment start point and the worst accumulation. 4. Note likely entry sources per segment. 5. File the card and photos as one dated record. Done when: Completed transect card with segment photos

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 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.
