Environmental Science & Remediation

Pollution threatens the health of our oceans and other critical water resources. Our environmental teams prevent the dispersal of harmful, anthropogenic contaminants into the planet’s waters and ecosystems. We also restore health to areas that have been damaged.

Identifying and eliminating toxins that imperil people & planet

As climate change and human activity diminish the supply of clean water, governments, companies, and people are increasingly – and appropriately – focused on the importance of preservation and restoration of our water resources. Protecting drinking water and the waters that flow into the oceans is our common priority.

Chemicals of emerging concern such as Per and Polyfluorinated Substances (PFAS, or “forever chemicals”), microplastics, and pharmaceuticals, as well as more well-known pollutants that are widespread in our environment, often drive urgent responses and are difficult to treat. Companies with a solid understanding of the environmental sciences and the ability to respond quickly with creative solutions have ample opportunity to assist.

Sealaska has a long history of success creating winning teams in the federal environmental market. Our relationships enable us to build early subject matter expertise with unusual problems and emerging contaminants and exposure pathways. We bring confidence to our clients who need an innovative path forward.

Our minority-owned businesses below offer a full range of environmental engineering, data sciences, consulting, and remediation services.

Nuclear Smuggling Detection and Deterrence (NSDD)

Protecting the environment takes many forms, some unexpected. Through its Tech2 Solutions joint venture with Tetra Tech, Inc., Sealaska provides engineering, design, technology integration, international logistics and construction management support for the installation of fixed and mobile radiation detection systems and associated infrastructure. The DICCE II Contract is administered by NNSA’s Office of Nuclear Smuggling Detection and Deterrence (NSDD) (formerly referred to as the “Second Line of Defense”), whose mission is to strengthen the capabilities and commitment of U.S. partner countries to deter, detect, and interdict illicit trafficking of nuclear and other radioactive materials within the interiors of partner countries, across international borders, and through the global maritime shipping system. This U.S. government nuclear nonproliferation program provides partner countries with the tools and training necessary to counter nuclear smuggling, thus making an essential contribution to the global nuclear detection architecture.


Kodiak Island Feasibility Study

The process of effectively removing contaminants from groundwater resources is difficult and expensive, so there is always a need for dynamic and innovative solutions to these challenges. When past operations at a formerly used defense site on Alaska’s Kodiak Island resulted in groundwater contamination, the SRS team was retained to install a pilot system and conduct testing of a groundwater treatment technology designed by others. While the objective of the project was to acquire final design and installation parameters for a full-scale treatment system, SRS remediation experts determined that newer, more innovative methods were available. The in-place cleanup approach recommended by SRS eliminated the need for large amounts of electricity and a permitted discharge to surface water. This was especially beneficial because the site is located near one of Alaska’s most productive river fisheries.

Dworshak Dam

Columbia River Basin Projects

As climate change and human activity diminish the supply of clean water and upset the balance of our delicate ecosystems, Sealaska is eager to focus its scientific and technical skills on these threats. Both STS and SRS have a longstanding relationship with the United States Army Corps of Engineers (USACE) and have performed many projects - including freshwater resource development, ecosystem protection and renewable hydropower support - in the Columbia River Basin to assist them in their civil and environmental missions. One such project was completed recently to help the USACE Walla Walla District study the feasibility of adding an additional hydropower unit at the Dworshak Dam near Orofino, Idaho. Sealaska’s work included conducting an environmental evaluation with accompanying hydrologic, water-quality, biological, and cultural resources-impact study. The report provided to the client enabled them to determine if they could move forward with the renewable hydropower project while still being protective of valued ecological and heritage sensitivities.
