Bob’s goal has been to build the “institution” for institutional controls. The building blocks include a strong understanding of regulatory and technical requirements of stewardship, and an arsenal of multiple information and mapping techniques. Bob is a registered civil engineer, graduate of Stanford and is a founder and now CEO of Terradex, Inc.
Mix 400,000 daycares with 550,000 cleanup sites nationwide, and the vision takes shape for a national daycare screening service to vigilantly protect 6,000,000 children from inadvertent exposure to toxics. This effort started after 2006 on the failings at Kiddie Kollege, where children attending daycare were exposed to high mercury levels. The childcare facility occupied the same building that [...]
In both a progressive and unique move, the West Virginia DEP joined the state’s call-before-you dig, or “One Call” center to help screen for improper excavations at about 100 of the state’s environmental covenant sites. The process requires a daily review of excavation tickets at or near these site which, in turn, allows DEP to [...]

As the task group chair for ASTM’s Continuing Obligations Guide, Terradex’s Bob Wenzlau shares his personal encounter with a failed remedial system, the difficult to report [...]
Seven years ago, we created a new methodology for increasing the effectiveness of institutional controls, and as of June 29, 2010 this innovation is protected by a patent. So what led to the patent? Failed approaches led to a new idea. We knew a duty existed to monitor safe use of contaminated sites, but whose [...]

Thorough real estate monitoring is critical when the responsible party no longer owns [...]
A strategic direction for Terradex has been to augment federal stewardship of environmental sites with our LandWatch service. The Association of State and Territorial Solid Waste Managers invited Terradex to present at their symposium Beyond Construction Completion: Long-Term Protection of Human Health and Environment at Federal Facilities. Terradex LandWatch is monitoring numerous federal facilities including active [...]
On April 14, 2008 Terradex was awarded a 2008 Environmental Achievement Award. In the award the agency cited Terradex’s groundbreaking work in communicating environmental information to the public enables individuals and communities to make informed decisions regarding both exposure and contaminant contributions.

Reporter Lyanne Melendez of KGO TV reported on the Association of Bay Area Government’s effort to confront global warming. San Jose Councilmember Cortese liked the online Terradex emissions models.

Terradex avoided a “disaster” threatening the potable water in Los Angeles, according to the United States Environmental Protection Agency. The local permit agency approved the installation of a cathodic protection well. This type of deep well, used to prevent pipeline corrosion, has perforated walls and can thus allow groundwater to flow downward from a shallow [...]
In October 2005, Bob Wenzlau of Terradex was appointed Task Group Chair to build a practice standard for Landowner Continuing Obligations. When complete, the practice standards will systematically improve the long-term public and environmental safety at brownfields while limiting financial liabilities brownfield redevelopers. The Task Group includes participation from USEPA, state government, brownfield redevelopers, environmental [...]
