Toxicity Identification Evaluation

TIEs have become an integral forensic method for determining causes of toxicity. The success of TIEs in identifying the causes of toxicity that may be present in effluents, ambient waters and sediments is a direct function of the technical expertise of the scientists regarding the fate and effects of potential contaminants. Our staff are very experienced in the performance of both acute and chronic Phase I, Phase II, and Phase III TIEs and have successfully completed numerous TIE/TRE studies for a wide variety of the municipal and industrial groups throughout the U.S.

Pacific EcoRisk is expert in the preparation of TRE workplans and in the performance of all aspects of Phase I, Phase II and Phase III TIEs and benchscale TREs, and has earned a reputation for efficient, cost-effective services.

TIE and TRE procedures are performed on:

• Industrial and municipal effluents

• Ambient surface waters

• Storm water runoff

• Whole sediment, sediment elutriate, and sediment porewater matrices
