In-Situ Sediment Remediation Technology Developed and Patented by NASA
In-Situ Sediment Remediation Technology Developed and Patented by NASA
SPEARS (Sorbent Polymer Extraction and Remediation System) is a transformative, in-situ remediation technology that extracts PCBs, dioxins, DDT, and other persistent toxins from contaminated sediment without damaging the natural aquatic habitat by dredging or capping.
ecoSPEARS is the only sustainable remediation method that extracts toxins from the contaminated sediment while protecting the aquatic life by preventing the toxins from being bioavailable to the fish and other marine life.
Sustainable Approach
Unlike dredging and capping, which can destroy the aquatic marine life, SPEARS absorb the toxic contaminants without displacing the sediment or disrupting the marine life.
NASA-Developed
SPEARS technology was developed, validated, and patented by NASA. ecoSPEARS has the exclusive license from NASA to deploy the revolutionary technology across the world.
Cost-Effective
SPEARS extracts the contaminants at a fraction of the cost without the need for digging and hauling.

How SPEARS Work
The technology is comprised of a specialized mat which contains an array of polymer “SPEARS” that are filled with our proprietary solvent to absorb toxins.
The mats are pressed down into the contaminated sediment, where they absorb toxins like a sponge. Once remedial levels are achieved, the SPEARS are removed from the sediment.

Internationally Recognized
ecoSPEARS is written into the International Pollutants Elimination Network (IPEN) Non-Thermal, Non-Combustion Technology for POP’s Waste Destruction and the United Nation’s Environmental Program (UNEP) Stockholm Convention Best Available Techniques (BAT) and Best Environmental Practices (BEP) Guidance for the management of sites co-contaminated with persistent toxins.

Sediment Stabilization
Taking inspiration from the natural design of mangrove trees, SPEARS provide sediment stabilization, effectively reducing erosion and limiting the dispersion of contaminants.
Eco-Friendly
Unlike dredging or capping, SPEARS offers an environmentally friendly, non-invasive solution that is ideal for sensitive marine and wetland areas. The geosynthetic SPEARS mats are designed with ports to facilitate the flow of water above and below the mat, allowing native fish and plant life to flourish. By eliminating the necessity for dredging, SPEARS significantly minimizes disturbances to boat and maritime traffic, rendering it an excellent choice for ports, harbors, and other high-traffic waterways.
Smarter Site Characterization
SPEARS serves as a precise tool for both delineation and remediation. SPEARS can pinpoint “hotspots” within contaminated sites at depths reaching up to 36 inches. This high-resolution analysis enhances site characterization, aids in remedial planning, and facilitates improved risk assessment.
