UV oxidation can be used to treat many types of organicexplosives-contaminated water, including process waters from thedemilitarization of munitions (pink water) and ground watercontaminated from disposal of these process waters.
Treatment of Water Contaminated with the High Explosive
treatment for RDX and HMX contaminated water treatment. RDX and HMX are sparingly soluble in water (50 mg/I, and 5 mg/L at 25°C, respectively) (Gibbs and Popolato, 1980) . When hydrolyzed directly, without pre-concentration, large amounts of water have to be heated and a lot of NaOH has to be added in order to reach the necessary temperature and pH.
High explosive contaminated wastewater is generated from the machining of high explosives at Pantex Plant. The water is used as the coolant during the machining operation. Typically, the water flow rate is from 2 to 3 gallons per minute. The water must be tempered to about room temperature so that it does not affect the dimensions of the explosive piece being machined.
Remediation of Explosives Contaminated Groundwater with
because the dissolved oxygen concentration is high. A series of column experiments were conducted at the site: including columns with 10%, 20%, 30%, and 100% iron by volume is silica sand. In all of these cases, oxygen is rapidly scrubbed from the water by the iron.
It has been estimated that there are hundreds of explosives-contaminated sites within the United States, and even a greater number in Europe and Asia. TNT, rapid detention explosive (RDX), and high melting explosive (HMX) are the most commonly found explosive substances in soil. Figure 1 shows

LOS ALAMOS, N.M. -- In an initiative supported by EM, Los Alamos National Laboratory' s Corrective Actions Program is addressing high explosive contamination in surface water and groundwater at a location this summer in the forests surrounding the laboratory. A high explosive called RDX was machined at the site beginning in the 1950s as part of the laboratory’s weapons development mission.
Hazardous contaminated sites in the North and the Baltic Sea
Millions of tons of old ordnance and poison gas grenades lie at the bottom of the North and the Baltic Sea – dangerous legacies of two world wars. The old weapons are corroding and releasing the
Aqueous alkaline hydrolysis of bulk quantities and wastewater contaminated with high explosives is a promising technology for treatment and disposal of the worldwide surplus of munitions. We investigated the hydrolysis kinetics of the high explosives hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) and octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX) for temperatures ranging from 50 to 80
Decontamination and Dismantling (D&D) of Explosive
Impact – The impact of dropped tools on a contaminated pipe can be sufficient to ignite explosive contamination. Contaminated piping can either be struck by another tool or it can be dropped accidently during dismantling. Pape, et al. (1982) estimate that the likelihood of a person’s accidentally dropping an item is 1x10-3 / operations.
