Clear litter from the Sacramento River levee trail in Colusa (2026-07-19)

The levee trail along the Sacramento River in Colusa collects wind-blown trash from the adjacent riverside park, and that debris washes downstream with every rise in river flow. A hand litter sweep keeps the bank cleaner for the anglers and walkers who use the levee daily. Standard: EPA urban stream cleanup method + SDG 15 Proof: Photo of cleared stretch, bag count logged Method (EPA urban stream cleanup method + SDG 15): 1. Walk a defined 0.5-mile stretch of the levee trail with gloves and a trash grabber. 2. Bag litter separately from recyclable material. 3. Stay on the trail and levee top — do not enter the river. 4. Photograph any larger dumped item without attempting to move it alone. 5. Weigh or estimate total bags collected. 6. Photograph the cleared stretch and bagged total. Done when: Photo of cleared stretch, bag count logged

$140 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.

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.
