Summary Information
(last updated on: 2/14/2019 2:09:47 PM)
On the Tektronix Beaverton Campus within Evaluation Area 1, DEQ issued a Record of Decision (ROD) for cleanup in 2009 selecting in-situ thermal remediation for volatile organic compound (VOC) source areas and monitored natural attenuation of groundwater outside source areas. More recent groundwater data has shown VOCs in the source area at Beaverton Creek have significantly declined and no longer require treatment but subject to monitoring. Results from a supplementary groundwater investigation completed in 2013 at the Building 38 source area indicate treatment may be necessary but bioremediation would be more suitable. DEQ will determine appropriate action will be after additional data collection and groundwater monitoring of recently installed wells. A supplementary investigation was also completed in the former Building 40 source area in 2014 and 2015, resulting in a refined treatment area.

A pilot test using in-situ thermal remediation was completed in 2012 and proven a viable treatment technology for high concentration areas. However, given significant increases in cost to treat the remaining source area(s), DEQ agrees Tektronix can pursue enhanced bioremediation technology as a cost-effective alternative. Approval of this treatment alternative is subject to conditions agreed upon by DEQ and Tektronix. DEQ’s memorandum, "Explanation of Significant Differences", dated August 2015, documents DEQ's determination that modifications to the remedy are acceptable based on more recent information/data. Tektronix conducted bioremediation injection activities in 2016-2018. Performance monitoring results will determine the need for additional substrate injection.

Within the remaining Evaluation Areas, 2 through 6, Tektronix has completed several phases of investigation to evaluate whether any unacceptable risk is present on this portion of the site. A Human Health Risk Assessment Report was completed in August 2013, which DEQ concurred with the findings. A final Remedial Investigation report for EA2-6 was submitted in 2017.
