Year	Month	Action/Results	Action Performed By	Project Number
Unknown	Unknown	Four trenches used to dispose of spent ammunition, small spent rockets, and other metal scrap.	CSSA	NA
1993	September	Area visually identified during field survey.	Parsons ES	Order 71
1995	March	EM geophysical survey performed on March 8 and 10; three anomalies found (four disposal trenches).	Parsons ES	Order 67
1997	March-September	UXO recovery work conducted. To remove UXO, material in four trenches was excavated and sifted. Approximately 5,485 cubic yards of soil was sifted and stockpiled onsite.	Parsons ES UXB	RL33
	June	Preliminary soil sample collected to identify contaminants at the site. Analytical results are currently in question due to ITS Laboratory practices.	Parsons ES UXB ITS	RL33

	November	Submitted work plan for resampling to replace analytical chemistry data generated by ITS Laboratory.	Parsons ES	NA
2000	March	Advanced 5 soil borings and collected 15 soil/rock samples for VOCs, SVOCs, metals and explosives.	Parsons ES APPL, Inc. Data Chem	RL33
	April	Collected 10 sift samples for VOCs, SVOCs, metals and explosives analysis.	Parsons ES APPL, Inc. Data Chem	RL33
		Collected 18 sift samples for VOCs, SVOCs, metals and explosives (3 samples) and metals only (15 samples).	Parsons ES APPL, Inc. Data Chem	RL83
2001	January	Three additional soil samples collected from stockpiled soils were analyzed for the leachability of contaminants.	Parsons	RL33

2008	June	Collected 14 surface soil samples for arsenic, cadmium, copper, nickel, zinc, barium, chromium, mercury, and lead analysis.	Parsons	DY01
2009	April	Site mowed to allow access for geophysical equipment.  Geophysical survey preformed, numerous anomalies found over entire site.	Parsons	DO11
2010	April	Conducted MEC Hazard Assessment to evaluate the relative degree of hazard associated with the current site condition and for use in evaluating potential site closure options.	Parsons	DO50
	June	Performed XRF analysis at the site to determine the extent of metals in surface soils.	Parsons	DO50
	December	Performed XRF survey.	Parsons	NA
2011	February	Collected samples from soil overage pile and sifted through overage pile for MEC.	Parsons	NA
	March	Moved overage pile to East Pasture berm and collected surface soil samples at site.	Parsons	NA
2012	February	SWMUs B-2, B-8, B-20/21, and B-24 were combined with RMU-1 as part of the active firing range.  These sites will be investigated, remediated, and closed when the firing range is no longer active. USEPA Memorandum dated February 29, 2012.	USEPA	NA
