USEPA Releases Study Citing Terradex's Prevention of an Environmental "Disaster" to the Los Angeles Public Water Supply
Terradex avoided a “disaster” according to the United States Environmental Protection Agency (USEPA), threatening the potable water in Los Angeles. The local permitting agency missed the conflict with a benzene plume. However, Terradex proactively detected the excavation and thus allowed the responsible party to step in and prevent a cathodic protection well installation through the center of a benzene plume -- the installation of which would of breached an aquitard building a conduit to the potable supply aquifer of Los Angeles.
In February 2006, the USEPA released their two year evaluation of a multi-site case study conducted in California's Silicon Valley. The study tested Terradex's monitoring to numerous contamination sites including Superfund, BRAC sites, leaking underground fuel sites and brownfield sites. An extract from USEPA's report:
"A prime example of the potential of an IC monitoring system to protect the public and the environmental from exposure to contamination occurred in January 2006. While the Del Amo Superfund site was not technically part of the pilot program, many of the same parties using the same process employed in the pilot program, detected and prevented a disaster from occurring there. Chevron had proposed drilling a 300-foot well for cathodic protection of one of its pipelines. The local permitting agency missed a conflict with a benzene plume in the area of the planned excavation and permitted Chevron to drill the well. The IC monitoring service used in the pilot program, Terradex, alerted stakeholders to the conflict and Chevron canceled the drilling. Had the well been drilled, concentrated benzene would have polluted the Lynwood Aquiifer that supplied drinkable water to Los Angeles County. Chevron is now working with regulators toward a solution that will protect human health and the environment."
