Clear litter and invasive weeds along Weir Gulch, Weir Gulch at Westwood Park (segment 1) (2026-07-17)

Weir Gulch through Westwood carries trash and invasive weeds from the surrounding blocks; a hand-cleared segment is a real, repeating piece of this creek's health. Standard: US EPA Rapid Bioassessment Protocols + SDG 6.3/6.6 water quality & ecosystems; INAT01 stewardship waypoint protocol. Proof: before/after photo pair + haul log + GPS Method (US EPA Rapid Bioassessment Protocols + SDG 6.3/6.6 water quality & ecosystems; INAT01 stewardship waypoint protocol.): 1. Photograph the segment as found and note any hazardous or large-item debris (document, don't move drums/unknown containers). 2. Collect litter by hand along the banks, staying clear of the channel in any flow. 3. Hand-pull invasive weeds within reach of the bank, bagging seeded material for disposal. 4. Photograph the cleared segment from matching vantage and log the haul. Done when: before/after photo pair + haul log + GPS

Pay

$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 photo pair + haul 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.
