Sequoia Environmental Remediation Inc. services

Sequoia has the expertise and equipment to conduct short, medium, and long-term pilot testing for a variety of environmental contaminants, assisting our clients in developing full scale remediation solutions. We have a fleet of mobile piloting testing equipment specifically designed to test for: soil vapour extraction, multi-phase extraction, air sparging, chemical injection, groundwater pumping, groundwater treatment, and much more.

Sequoia has a team of highly trained field technicians, that are able to provide operations and maintenance to sites across Canada that contain environmental remediation equipment. Our technicians are fully trained journeyman with certifications and required courses to allow access to a variety of client sites with the most stringent of safety standards.

Sequoia is one of Western Canada’s premier environmental equipment manufacturers. Our reputation for designing and manufacturing robust, efficient, and operator friendly machinery is well known. We manufacture our equipment from the ground up, keeping most facets of construction in house.

Sequoia provides full-service remediation system and equipment installation including, but not limited to, electrical connection, sewer discharge connection, underground piping, manifolds, wellheads, and equipment enclosures. Installations can be optimized for cold climates to ensure year round operation.

Sequoia can provide trained field technicians and self-sufficient remediation equipment that enables us to successfully respond to emergency response calls. We can quickly mobilize, setup and operate our remediation and groundwater treatment equipment assisting our clients through surface spills of contaminants and other emergency scenarios where expedient professional response is critical.

Sequoia can provide telemetry and remote monitoring services on remediation systems. Notification of system alarms and data acquisition improve the efficacy of remediation systems. In addition to standard phone and email alarm notifications, the collected data is graphed and available to view remotely, reducing the need for operators to be physically present at site.

Sequoia is expertly equipped to inject amendments into the subsurface for the purpose of contaminant mass reduction, plume stability, or final polish for site closure. We have extensive experience injecting oxidants, nutrients, and activated carbon amendments. Injection programs can occur through direct push rods, dedicated injection locations, or monitoring wells when applicable. We work with our clients to determine the best amendment program for your site.

Sequoia provides pneumatic fracturing services to aid in the recovery of contaminants in tight soils. This technology pairs with other remedial techniques to increase mass removal.

Sequoia can provide all of the necessary equipment required to effectively pump and treat surface and groundwater generated during excavations. Our equipment is simple to operate and contains generators, pumps, sediment filtration, activated carbon filtration, and is contained inside of a heated container, ready to be deployed to your site for all seasons and weather conditions.

Sequoia has extensive experience in the collection and removal of liquid product from the subsurface. Whether using multi phase extraction, pneumatic product pumps, electric fuel pumps, sorbent socks, or manual product extraction, Sequoia has the experience and technology to maximize contaminant mass removal.
