# Organic Adsorption Media for NAPL Seep Isolation in Waterways

NAPL seep zones in waterways can cause continuous release of hydrophobic contaminants and complicate sediment remediation. Camp-Shinning provides **granular organic adsorption media** designed to capture oil and NAPL-related organics and support chemical isolation strategies in river and harbor environments.

## Why NAPL Seeps Need Targeted Isolation
– Seep release can persist even after dredging or capping
– Hydrophobic contaminants may migrate into porewater and surface water
– Residual NAPL can recontaminate clean cap layers
– Long-term controls are often required for risk reduction

## How Organic Adsorption Media Helps
When placed in targeted seep zones, adsorption media can:
– Capture NAPL-associated organics migrating upward
– Reduce dissolved hydrophobic organics near the sediment interface
– Support active cap performance in high-risk seep areas
– Help stabilize remediation outcomes over time

## Common Isolation Approaches
– Active cap layer placed directly over seep locations
– Localized treatment mats or media zones
– Integration with protective cover layers for stability

## Planning and Site Data Needs
For seep isolation design, teams typically review:
1. Seep location mapping and flux characterization
2. Target contaminant profile (oil/NAPL, PAHs, PCBs)
3. Hydrodynamic conditions and placement constraints
4. Required service life and monitoring strategy

## Supply Options
Camp-Shinning supplies project-ready packaging, including 25 kg bags and bulk logistics to support marine placement operations.

## FAQ

### Can adsorption media stop NAPL seep release?
It helps capture hydrophobic organics migrating from seep zones and reduces release into porewater and water column, supporting isolation goals.

### Is it compatible with sediment caps?
Yes. It is often integrated as an active layer beneath a protective cap cover.

### Does it help with PAHs and PCBs from seep areas?
Yes. Hydrophobic dissolved organics such as PAHs and PCBs can be adsorbed as they diffuse from sediments.

### What information is needed for selection?
Seep mapping, contaminant profile, and placement method are the key inputs for recommending volume and design approach.
