Another Site Achieves Closure

I am proud to announce that we have achieved closure for one of our clients at a property in Gardena, California.  Here is a little bit of information about the project: 

From the late 1980s to 1997, a manufacturer of metal fasteners for the aerospace industry and military was located at the site.  These former operations are reported to have included the use of Aboveground Storage Tanks (ASTs) and petroleum solvents.  The former property owner also operated a waste storage area near the center of the southern portion of the site.  The site is currently occupied by various tenants that utilize the property for warehousing, distribution, and small-scale manufacturing.  

Several phases of soil, soil gas, and groundwater investigations have been performed at the site between 1998 and 2006.  The primary objective of subsurface investigations at the site was to provide analytical data that will identify the nature and extent of PCE in soil and groundwater beneath the site.  To help meet this objective, a total of twelve soil borings have been advanced at the site to help characterize PCE in soil.  Three soil gas probes were advanced at the site to help characterize PCE in soil gas.  Additionally, GeoTrans installed and sampled groundwater monitoring wells at the site in two locations to characterize PCE in groundwater.  

Based on the results of this current program and previous soils investigations at the Site, GeoTrans concluded that very low concentrations of PCE are present beneath the southern portion of the Site.  We worked with the Los Angeles Regional Water Quality Control Board and concluded that the presence of this constituent at the concentrations detected during our site investigations is unlikely to pose a significant threat to human health or the environment. Therefore, no further work is warranted at this time in regards to soil and groundwater at the site.
