On August 18^th, consolidation of laboratory chemicals was completed. 8 drums (55-gal) of liquid lab chemicals, 1 drum (55-gal) drum of hydrochloric acid and 1 drum (55-gal) of sulfuric acid have been generated from the lab chemical consolidation.  These drums await shipments for offsite disposal.  In addition, 25 drums (55-gal) of dry lab chemicals, mostly QA/QC samples, were generated; this waste stream has already been shipped offsite for disposal in roll-off along with disassembled tanks. Lab packing of the remaining lab chemicals that could not be consolidated will ensue upon awarding of disposal subcontract.


On August 23^rd, shipments of reusable material to Summit Research Labs were completed.  Approximately 32,000 gallons of liquid in process chemicals and nearly 100 tons of dry off-spec materials have been shipped.  There is still a possibility for the partially spent aluminum ingots inside the reactor being accepted by Summit Research Labs.


Between August 23^rd and August 30^th, soil samples were collected throughout the stressed vegetative areas as well as perimeter samples around the stressed areas to a depth of 1 foot.  In addition subsurface soil samples were collected beneath the southwestern parking lot; location of the seep.  84 total soil samples were submitted for analyses, consisting of inorganic metals, zirconium, chlorides and soil pH. The pavement consists of three distinct layers of asphalt (historical).  It appears the seep originated from the building and traveled in between the two top layers of asphalt.
