This analysis of Boeing’s government-funded 2015 report on seeps in and around the Santa Susana Field Laboratory is supplementary material for the exposé Brandeis-Bardin’s Toxic Denial.

The page organizes important information in this Boeing and government-funded 6,549-page report, “Report on Seeps Investigation SSFL Summary of Work Completed through IQ 2015.” The breadth and scope of the toxins found in this report, its key mistakes and factually incorrect conclusions are presented clearly and concisely. This page has made it possible for readers to see the data themselves.

Over a dozen Brandeis-Bardin sites are documented as having toxin detections present are tallied and described in two sections of the report. EnviroReporter.com clearly combines these two parts into one for an easier understanding of the data. EnviroReporter.com’s questions and remarks are in brackets, highlighted in yellow along with notable parts of the selected data.

Brandeis-Bardin seeps designations and comments where Boeing admits toxin found is a “common laboratory contaminant” are bolded and highlighted in pink. Do note that toxins attributed to SSFL in the pink-highlighted seeps are found in seeps throughout Brandeis-Bardin that Boeing has provided data for in this report. All of these toxins are highlighted in yellow.

Funding for the seeps investigations was provided to the University of Guelph by The Boeing Company, the US Department of Energy, and the National Aeronautics and Space Administration during the period of 2008 to 2013, and for 2014 Boeing provided the funding support. Additional support for methods development was provided by Boeing and the National Sciences and Engineering Research Council of Canada.

Private property owners denied access to off‐site locations where work was proposed in the 2012 Seeps Work Plan that included two proposed seep well cluster locations, three areas to be inspected for seeps, and three seep sampling locations. [ER – P 87/6,549 indicates Dayton Canyon area]

P. 38/6,549:

III. Seep Cluster Well Installation and Sampling
Perchlorate has not been detected at any SSFL seep, and no VOC has ever been confirmed to be present at any off‐site seep location. As discussed in Section II above, TCE and its degradation products have been detected persistently at three on‐site seep locations within the SWD. Due to natural mechanisms that retard and attenuate plumes, such as matrix diffusion, dispersion and degradation, it is not expected that COCs will be found at off‐site discharge locations. To verify the analytical results of discharge water collected directly from the seeps (Figure 37), and to test the hypothesis that the SSFL plume fronts have not reached seeps, it is necessary to sample various groundwater flow paths to determine whether the absence of COCs in seep discharge is due to dilution with local water, potential volatilization of VOCs as seeps water discharges, degradation, or true absence (Figure 38).

[ER: Perchlorate detections in this report contradict the “not been detected” statement. The preceeding pseudo-science says that their “hypothesis” is that no VOC has reached the seeps because when it did it evaporated. But doesn’t that mean that the VOC was there in the first place? And what about all those positive readings of VOCs in Brandeis-Bardin? Did they not show that VOCs and TCE are in the seeps with positive detections even with evaporation? Of course they did as this special EnviroReporter.com page shows. The evidence is in their own report where they attempt to float this “hypothesis.” This is not a new tactic. Find numerous examples of contaminants, post the documentation in dense reports on DTSC’s website, and still declare the place safe enough for folks to hike as we exposed in Critics question safety of Boeing’s Santa Susana Field Lab hikes.]

Affected Organ Systems: Cardiovascular (Heart and Blood Vessels), Neurological (Nervous System)

Cancer Classification: None

Chemical Classification: Hydrocarbons (contain hydrogen and carbon atoms), Volatile organic compounds

Summary: Toluene is a clear, colorless liquid with a distinctive smell. Toluene occurs naturally in crude oil and in the tolu tree. It is also produced in the process of making gasoline and other fuels from crude oil and making coke from coal. Toluene is used in making paints, paint thinners, fingernail polish, lacquers, adhesives, and rubber and in some printing and leather tanning processes.


• Toluene enters the environment when you use materials that contain it. It can also enter surface water and ground water from spills of solvents and petroleum products as well as leaking underground storage tanks at gasoline stations and other facilities.

How might I be exposed to toluene?
Living near uncontrolled hazardous waste sites containing toluene products.
Toluene is not frequently detected in drinking water
or food.

How can toluene affect my health?
Toluene may affect the nervous system. Low to moderate levels can cause tiredness, confusion, weakness, drunken-type actions, memory loss, nausea, and loss of appetite. These symptoms usually disappear when exposure stops.
