Remediation Systems (Air, Soil and Groundwater)

When a property has been affected by contamination, it may be necessary to pursue remedial efforts to correct the issue. Seneca Companies’ experienced team of OSHA trained engineers, tradesmen, site supervisors and project managers can design, install, build and operate domestic or international remediation systems to help remove any subsurface contamination a property may contain. We are proud to provide custom solutions to solve any number of remedial challenges our clients may be facing. Our remediation systems are built for a wide range of applications including the commercial, industrial, government and environmental sectors.

Seneca has Remediation and Process Control Shop - an Underwriter’s Laboratory (UL) listed facility. We have provided over 2,000 turnkey packaged systems to clients throughout the world. All control panels are custom built by licensed master and journeyman electricians. Each system is fully tested prior to delivery. Seneca understands complex electrical codes including Class I, Division 1 and 2, Hazardous Locations. The safety of both the public and our client’s employees is top priority.

Seneca’s unique, central location allows for easy shipping of a system. Upon completion of approved CAD drawings, our systems can typically be delivered between 8 to 10 weeks. Rental and leasing options for systems are available.
