Descriptions of Areas of Concern
The Small Arms Range Safety Fan was identified and listed as a Closed Range in the 2002 Phase 3 Range Inventory Report and as a Military Munitions Response Program site. A Historical Review was completed in 2004, and a Site Inspection is underway to evaluate the need for further investigation, remedial action, or no further action and site closure. | |
The Ammunition Demolition/Burning Area site was identified and listed as a Closed Range in the 2002 Phase 3 Range Inventory Report. However, upon further evaluation it was determined to be ineligible for the Military Munitions Response Program. The area is co-located with the OB/OD Area, and individual sites within the area are being evaluated by either the Installation Restoration Program or OB/OD Area Closure Program. | |
The Old Explosive Ordnance Disposal Demolition Area covers approximately 34 acres. It was actively used for ordnance demolition between 1942 and 1945 and again in 1961, and for training at other times. Demolition activities focused primarily on the destruction of high explosive (HE)-filled ammunition in shell sizes up to 155-mm, but some white phosphorus-filled projectiles and small arms ammunition were also detonated occasionally, and 50-caliber machine guns were fired into the bordering hillside. An open disposal pit contained slugs, ammunition boxes, small arms brass, and other debris, and appeared to be the site of a former small arms burn cage. Remedial investigations were conducted in 1995-1996, and additional investigations are planned to further evaluate the need for remedial action. | |
| |
The Former White Phosphorus Detonation and Burn Area was used for the destruction of white phosphorus and conventional munitions from 1945 through the mid 1970s. Two 250-pound bombs filled with blister agent (mustard) were vented, detonated and burned during the mid-1950s. Subsequent testing of the area did not detect mustard agent or mustard agent residues. A portion of the area was reportedly used for burning mercury-contaminated pallets and water containing 2,4,6-TNT. Other historical operations include the burning of plasticized white phosphorus (PWP) and red phosphorus ammunition. The Closed Open Burn Area (NAAD 09C) landfill is located on the canyon wall, and may have contributed contamination to the canyon floor of NAAD 03. Remedial investigations were conducted in 1996-1997, and addition investigations are underway to further evaluate the need for remedial action. | |
| |
The Former Open Burn Area, an approximately 27 acre site, was used from the 1940s to early 1990s for burning explosives-contaminated materials, bulk explosives and propellants. Dunnage and munitions containers were burned on the ground or in the burn cage. Napalm-filled bombs were burned in 1967 and 1968. After 1986, burn pans were used to burn bulk dry propellant. Remedial investigations were conducted in 1996-1997, and addition investigations are underway to further evaluate the need for remedial action. | |
The OB/OD Waste Pile and Burn Area is an approximately six acre site used to dispose of waste materials from burning and detonation activities from the 1940s to the late 1980s. The waste materials, which included pallets, wire, wood containers, and other potentially explosives-contaminated materials, were piled, burned, and landfilled at the site. Remedial investigations were conducted in 1996-1997, and addition investigations are underway to further evaluate the need for remedial action. | |
The Closed TNT Retention Ponds consist of 12 lagoons that received wastewater from the TNT Washout Facility (NAAD 11B) in the 1950s and 1960s. The wastewater was allowed to infiltrate and evaporate in the lagoons and the solid residues were periodically burned. Remedial investigations were conducted in 1995, and remedial actions were implemented, including the excavation and bioremediation of TNT-impacted soil in 1999. Additional investigation is planned to evaluate the need for further remedial action. | |
The Former Open Burn Area (Ponds) consist of six ponds that received wastewater from explosives processing facilities at Camp Navajo. The wastewater was allowed to infiltrate and evaporate in the lagoons and the solid residues were periodically burned. Remedial investigations were conducted in 1996, and remedial actions were implemented, including the excavation and bioremediation of TNT-impacted soil in 1999. Additional investigation is planned to evaluate the need for further remedial action. | |

This Closed Open Burn Area, consisting of approximately 4.6 acres, was used for the burning of ammunition boxes from the 1940s through the 1980s. The ammunition boxes contained various types of propellant. Remedial investigations were conducted in 1996, and addition investigations are planned to further evaluate the need for remedial action. | |
This Closed Open Burn Area, consisting of approximately 8.3 acres, was used for the burning of ammunition boxes and fiber tubes from the 1940s through the 1980s. The area includes surface features such as detonation craters, trenches and shallow depressions, and debris consisting of metal banding, tube ends, and shrapnel. Remedial investigations were conducted in 1996-1997, and in 2004 the site was integrated into the Open Detonation Area (NAAD 02) for additional investigation to further evaluate the need for remedial action. | |
| |
The Current Open Burn Area, consisting of approximately 1.5 acres, is located on Pad#4, which was used to temporarily stage munitions prior to disposal in the OB/OD Area. Occasional burning of small amounts of propellants may also have occurred here. In 1991 through 1993, burn pans were used at the site to burn propellant residues. Remedial investigations were conducted in 1996, and addition investigations are underway to further evaluate the need for remedial action. | |
Building 316, the Laundry Facility, was used to launder uniforms worn by personnel working in the Ammunition Workshop Area. Laundry wash water drained to lagoons south of the TNT Washout Facility (NAAD 11B). Underground storage tanks contained diesel fuel for the water boilers. Remedial investigations were conducted in 1995, and remedial actions were implemented, including the removal of tanks and excavation of fuel-impacted soil. The site is awaiting closure pending concurrence by ADEQ. | |
Buildings 318 & 319, the TNT Washout Facility, was used for the demilitarization of ordnance and recycling of explosives until the 1970s. Wastewater generated during the process was discharged to surface impoundments south of the building or to settling and filtration tanks in Building 319. Remedial investigations were conducted in 1995-2002, and remedial actions were implemented, including the excavation of TNT-impacted soil in 1996, the decontamination and demolition of Building 319 in 1998, the excavation and bioremediation of TNT-impacted soil and water in 1999, and excavation of TNT-impacted soil in 2002.

Building 334, the Former Deactivation Furnace, and an ash disposal pile and a storage room in Building 325, were used intermittently from 1961 to 1989 for the demilitarization of ordnance less than 800 grains, including small arms ammunition, tracers, primers, detonators, delays, and fuses. The process produced metal and ash containing lead, brass, iron, and barium. The recovered metals were sent offsite for recycling and the ash was piled on the ground. Remedial investigations were conducted in 1988-1989 and 2002, and remedial actions were implemented, including demolition of Building 334 in 1989, removal of the ash pile in 1992, demolition of Building 325 in 1996, and excavation of lead-impacted soil in 2002. The site is awaiting closure pending concurrence by ADEQ. | |
Building 322 was used for the degreasing, cleaning and spray painting of ammunition; it contained four stripping tanks and two paint booths. Drains from the stripping tanks and/or paint booths discharged into a nearby drainage channel and field. NAAD 14A addresses the specific concern of the stripping tanks. NAAD 14D addresses the specific concern of the paint booths. Remedial investigations were conducted in 1995-1996 and 2002, and remedial actions were implemented, including the excavation of lead-impacted soil in 1996, and the decontamination and demolition of Building 322 and the excavation of soil in 2004.

The Old Earth Reservoir was originally built by the Santa Fe Railroad prior to the construction of Camp Navajo to collect runoff water from the nearby springs. They were not intended to act as reservoirs for operations conducted at Camp Navajo, but historical references to the earthen reservoirs as "chemically-treated ponds" have been made. Other references suggested that the reservoirs may have received waste acids and paints generated from operations associated with Building 327 (NAAD 14G).
