Sweep the Antioch riverfront clean along the San Joaquin before the wind takes it (2026-07-19)

The public riverfront at Antioch's marina and fishing pier collects bait packaging, bottles, and wind-blown trash that goes straight into the San Joaquin River — the water that feeds the delta's fisheries. The people who fish this bank are mostly local subsistence anglers. A monthly sweep keeps their bank clean and the river cleaner. Standard: California coastal/river cleanup data-card protocol; SDG 14 (Life Below Water). Proof: Before/after bank photos plus weighed tally Method (California coastal/river cleanup data-card protocol; SDG 14 (Life Below Water).): 1. Walk the public riverfront path from the marina to the fishing pier with bags, gloves, and grabbers. 2. Collect litter from the paved bank and dry upper edge only, never the riprap or waterline. 3. Tally the top item types on a data card and sort recycling out. 4. Weigh bags and stage them at the marina trash point. 5. Photograph the bank before and after plus the tally card. Done when: Before/after bank photos plus weighed tally

$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.

Proof

Before/after bank photos plus weighed tally

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.
