Clear litter from the paved canal-edge walkway near Barrio Obrero (2026-08-03)

The paved walkway along the Cano Martin Pena canal collects blown litter and dumped trash on the land side, though the canal water itself is off limits to hands-on work. Clearing the walkway and bank keeps that litter from ever reaching the water. Standard: SDG 6, Clean Water and Sanitation, land-side litter prevention Proof: Before/after photos show the walkway cleared of litter Method (SDG 6, Clean Water and Sanitation, land-side litter prevention): 1. Stay on the paved walkway and land side; do not enter or wade into the canal 2. Walk the walkway and collect visible litter into bags 3. Sort recyclable material from general trash 4. Bag and stage collected debris for pickup 5. Photograph the cleared walkway section Done when: dated before-work photo; dated after-work photo; GPS location tag; written log of date and conditions found

$180 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

• dated before-work photo
• dated after-work photo
• GPS location tag
• written log of date and conditions found

Proof is measured against these, not judged by taste.

The standard this serves

Watershed Health. A watershed is everything the land pours into a stream, and the stream keeps the record. The EPA's bioassessment method reads that record through the small creatures living in the gravel: mayflies and caddisflies mean clean water, only worms and midges mean trouble. Mastery looks like a person who can wade one riffle with a net and tell you how the whole valley is doing. That skill is built sample by sample. This packet is one of them: one site, one careful count, one entry in the long record of a stream.
