Screen dry weather storm drain outfalls at Walter E. Long Metropolitan Park at Decker Lake, Austin, TX

Outfalls draining toward Walter E. Long Metropolitan Park at Decker Lake can carry dry weather flow that signals an illicit discharge upstream. This large public lake park sits in northeast Austin. The crew screens for conductivity and detergents from a safe public vantage and never enters the storm drain. Standard: EPA IDDE dry-weather screening; SDG 6.3 Proof: photo of outfall + GPS + conductivity/ammonia/surfactant readings Method (EPA dry-weather / AMD field screening, ~30-60 min): 1. Navigate to the outfall/reach; record GPS; photograph it, capturing any visible flow or staining. 2. Note whether flow is present in dry weather (yes/no). 3. Measure and record pH, conductivity, and each specified analyte per kit instructions. 4. Log any color, odor, floc, or aquatic-life observation. 5. Enter all readings with units, GPS, time, and photos into the proof record; sign. Equipment: GPS phone, pH meter or strips, conductivity meter, ammonia + iron test kit as specified, surfactant screen if specified, gloves, camera Done when: pH + conductivity recorded with units; Each specified analyte recorded with a value; Dry-weather flow present? recorded yes/no; GPS waypoint + timestamped photo

$240 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

photo of outfall + GPS + conductivity/ammonia/surfactant readings

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.
