Project Detail

Corps Nav Dredging Sediment Toxicity Assessment

Purpose

Evaluate toxicity within areas dredged by the Corps of Engineers for nav channel maintenance

Objective

Use sediment toxicity tests to test MPEQ predicted toxicities based on CBSQG ESB values over a range of predicted tox incidence. Sites with the highest PAH values are estimated with the highest toxicity incidence. Assess toxicity near Fountain City Service Base, which has PCB history and typical boat harbor activities. Test relationship between PAHs and sediment toxicity.

Study Design

Collect sediment from 5 sites along PAH gradient. SLOH testing H. Azteca & C. dilutes.
