Table 2.3 - Medium Priority SWMUs

Unit No.	Status Priority	Main Use	Historic Use (notes from Environmental Assessment, September 1993)	Field/Geophysical Results	Approximate Location	Expected Field Effort 1 Activities	Expected Soil Borings	Expected Sample Analyses
B-1	Med.	B/Ds	Powder and ammunition burn area used in 1954 for burning powder and incendiary materials. This information was field verified through areas of stressed vegetation.	No anomalies found (EM or GPR); surficial contamination; soil borings drilled at site.	North Pasture	None	Three	SVOCs, metals
B-8	Med.	B/Ds	Fired small arms ammunition brass area consisting of piles of fire bricks and ammunition shells and remains.	One anomaly was found during geophysical survey.	North Pasture	None	Three	VOCs, metals, explosives
B-9	Med.	D	Miscellaneous solid waste (metals and weapons) disposal area. The field survey indicated mildly stressed vegetation, but no indication of ammunition.	Needs geophysical survey.	Lower east pasture of CSSA	Locate, map, geophysical survey, three surface soil samples	None	VOCs, SVOCs, metals, explosives
B-12	Med.	D	Landfill area for large pieces of scrap metal and weapons were embedded in the 20-foot high hillside and in adjacent pond.	No anomalies found during geophysical survey; surface trash.	Behind the F-14 storage area	None	Three	VOCs, SVOCs, metals, explosives
B-13	Med.	D	Engineering trash dump area. Field survey indicated an area where miscellaneous solid waste was disposed of. This area has been covered and semi-compacted, but there are several areas where the cover has eroded, revealing the trash.	Geophysical survey needs to be conducted.	East of quarry	Locate, map, geophysical survey, three surface soil samples	Three	VOCs, SVOCs, metals
B-19	Med.	D	Miscellaneous solid waste, metal, and weapons identified on CSSA's original list.	No anomalies found during geophysical survey; soil borings drilled at site.	West of oxidation pond	None	Three	VOCs, metals
B-27	Med.	D	Sanitary landfill.	Needs geophysical survey.		Locate, map, geophysical survey, three surface soil samples	None	VOCs, SVOCs, metals
B-29	Med.	D	Old quarry area used for disposal of miscellaneous solid waste, munitions, and construction debris. A decayed drum of nickel penetrate was observed during field survey.	Needs geophysical survey.	SE of munitions maintenance area	Locate, map, geophysical survey, three surface soil samples	None	VOCs, SVOCs, metals, explosives
B-30	Med.	D	Area where miscellaneous construction debris was disposed. Field survey indicated scrap concrete, roofing shingles, and construction trash.	Needs geophysical survey.	SE of active facility, behind the quarry	Locate, map, geophysical survey, three surface soil samples	None	VOCs, SVOCs, metals
B-31	Med.	D	Sand and projectiles from Building 90 test range used as pipe bedding.	Needs geophysical survey.	Northeast of Building 92	Locate, map, geophysical survey, three surface soil samples	None	Metals, explosives
B-32	Med.	D	Sand and projectiles from Building 90 test range used as pipe bedding.	Needs geophysical survey.	North side of Building 34	Locate, map, geophysical survey, three surface soil samples	None	Metals, explosives
B-33	Med.	D	Sand and projectiles from Building 90 test range used as pipe bedding.	Needs geophysical survey.	South side of Building 45	Locate, map, geophysical survey, three surface soil samples	None	Metals, explosives
B-34	Med.	D	A drain in the locomotive maintenance pit is connected to a pipe which drains into a ditch which leads ultimately to Leon Creek.	Needs geophysical survey.	Near Building 28 (locomotive maintenance building)	Locate, map, geophysical survey, three surface soil samples	None	VOCs, SVOCs, metals
B Burning or detonation D Disposal - depth unknown Ds Surficial deposition Note: Because the medium priority sites have known waste residues or subsurface disturbances, these sites were be addressed in field effort 2 in addition to field effort 1.
