Statement from E.P.A. Region Seven Administrator Karl Brooks on West Lake Landfill

(Lenexa, Kan., April, 30, 2014) - On April 29, I received a letter from Missouri Attorney General Koster suggesting that E.P.A. conduct off-site soil sampling for radiological material associated with the leached barium sulfate waste buried at West Lake Landfill. E.P.A. appreciates the Attorney General's recommendation.

One concern in the Attorney General's letter references haul routes that were used to bring the radiological material to West Lake Landfill. It is important to note that soil sampling has already been conducted along the haul route from the Hazelwood Interim Storage Location (HISS) to West Lake Landfill. This testing was conducted by the Saint Louis U.S. Army Corps of Engineers FUSRAP in support of their 2005 Record of Decision (ROD) for the North Saint Louis Co. sites. A total of 231 samples were collected and analyzed by FUSRAP for Radium-226, Thorium-230, Thorium-232, and Uranium-238. None of the samples collected exhibited radionuclide concentrations exceeding the suggested surface and subsurface soil remediation goals identified in that Record of Decision.

Region seven last Friday received information from Dawn Chapman, a Bridgeton resident, which suggested a potential radiation detection off-site at the Bridgeton Municipal Athletic Complex. The individuals collected the soil from a drainage ditch and not from the ball fields. Usefulness of the information provided by Ms. Chapman is limited due to the lack of a quality assurance/quality control project that was used during the collection and testing of the soil.

Radiation occurs naturally in our environment and is found in granite countertops, canary glass and other antiques like watches, which in most cases do not pose harmful exposure risks. For more details, see www.epa.gov/radtown.

E.P.A. is carefully reviewing the information provided by Ms. Chapman. It should be emphasized that the Missouri Department of Natural Resources (MDNR) conducted scientifically valid radiation dust sampling near the ball fields in 2013. The results of this testing show that the area remains uncontaminated from the radiologically impacted material (RIM) located in West Lake Landfill and the ball fields are suitable for use. The results of the state's sampling are accessible in the West Lake Landfill Radiological Survey Report, dated May 16, 2013, and accessible at the MDNR website at: https://www.dnr.mo.gov/env/hwp/fedfac/documents/2013-5-16-westlake-rad-survey-reportl.pdf.

All validated information accessible to the state of Missouri and E.P.A. indicates RIM remains confined to the Location and that the Location is currently protective of public health.

E.P.A. continues to work with the U.S. Army Corps of Engineers to provide oversight of the development of the work projects for the responsible parties' construction of the Isolation Barrier and continues to work towards the selection of a long-term remedy for the site. As E.P.A. continues developing our work plans, we'll assess all accessible data and make determinations that will address any remaining testing requirements.
