Aquatic Sciences

From freshwater to marine environments, our aquatic science team provides smooth sailings to managing environmental risks.

GSI scientists work with private and public-sector clients to provide innovative strategies for aquatic sites. We work closely with our clients to identify and manage the environmental risks, remediation, and support litigation for aquatic sites. Our goal is to reach cost-effective regulatory closure and attain site-specific compliance goals. These projects often include working with out client’s legal and internal technical team to identify and develop environmental mitigation strategies that are cost effective and minimize future liabilities.

We have additional specialized expertise in handling emerging contaminants such as PFAS and Microplastics in aquatic systems.


Assessment of Impact due to Partially Treated Wastewater Released into Ocean Waters.

Confidential facility, Southern California Coast, Pacific Ocean

Gathered data (toxicity sampling/studies, compilation of publicly available data) to support an analysis of impact due to the release of partially treated wastewater into a coastal area of the Pacific Ocean. This included the use of satellite remote sensing data to support turbidity estimates as well as sampling and use of additional toxicity data, public data on bacterial counts, and proper contextualization of human use scenarios to highlight that impacts to both ecological and human health were de minimis. This work culminated in a technical memorandum provided to the California Water Board.
