Terradex's technology is the basis of four services available across the United States:

• Institutional Control and Engineering Control Monitoring Service for the Responsible Parties: Institutional controls and engineered controls are the backbone of the long term remediation efforts at contaminated sites. For a single site or portfolio of sites, in one or multiple states, Terradex will collect land activity and use data, then compare the data to the restrictions within an institutional control or the specifications of an engineered control. Not only does this process increase an institutional control's effectiveness or help increase the reliability of engineered controls, it also builds a compliance record. With this service, the fulfillment of post-closure obligations can be;more reliable, protective and cost-effective. The service has been applied to leaking underground storage tank sites, brownfield sites, landfills, or federal-lead sites.
  
  
• Appropriate Care / Continuing Obligations for the Landowner: Terradex provides technology and field services to support fulfilling the CERCLA Continuing Obligations expected of property owners. Whether the owner qualifies as a bona fide prospective purchaser, contiguous property owner or innocent landowner, each holds an important interest in assuring that the Continuing Obligations are fulfilled. Terradex will track institutional controls, monitor inspections of engineered controls, monitor physical occupancy of a property, and inspect recording status of an institutional control. These are common elements of landowner responsibility to maintain a defense from CERCLA liability. Quite often states expect similar representations to provide equivalent state liability protection. These services can be tracked in one or multiple sites.
  
  
• Brownfield Redevelopment Services for Government: Terradex works with federal, state and local agencies to assist in the operation of institutional control tracking. At a state level this includes a work flow between local government and state agencies to efficiently allow efficient state participation in local development review of institutional control implementation. Terradex can also provide community notification, when institutional controls are applied, and notice provisions need implementation. At a local level, Terradex's technology provides a mechanism for redevelopment agencies to enforce institutional control when active, large-scale development occurs. Terradex's technology can become part of an agency's existing information services; or be a stand alone web-based service.
  
  
• Environmental Notifications to One Call Systems: State laws typically require owners of monitoring wells, engineering controls and any underground facility to monitor and clear excavations with the state-sanctioned utility clearance systems. Several responsible parties also use one call systems to prevent excavation into zones of environmental contamination associated with institutional controls. Terradex serves as an agent for the owner. Terradex staff will load the boundary of the engineered control or institutional control into the utility clearance system, will review notices generated by the one-call system, and provide a positive response to the excavator with required clearance information.
