What Problem TIGSED Helps Solve
At contaminated sediment sites, decisions about cleanup approaches can have long term cost and liability consequences. These decisions are difficult because sediment behavior is complex and changes over time.
TIGSED was developed to provide a science based, scenario driven understanding of sediment contamination dynamics.
How TIGSED Creates Value for Clients
TIGSED simulates contaminant transport within sediment systems, allowing teams to evaluate how contamination behaves over time and under different remediation approaches. It supports side by side comparison of MNR, EMNR, capping, and dredging strategies while accounting for site variability and uncertainty.
Clients rely on TIGSED to:
- Assess source contributions and recontamination potential
- Compare long term outcomes of remedial alternatives
- Inform allocation, remedy design, and regulatory negotiation
- Support conclusions with transparent, defensible modeling
Driving Better Decisions
TIGSED gives clients a clearer view of what actually drives sediment risk—and what does not. In regulatory and allocation contexts, that clarity can materially influence strategy, cost, long term exposure and regulatory acceptance.
