Preliminary assessment of perchlorate in ecological receptors at the Longhorn Army Ammunition Plant (LHAAP), Karnack, Texas.

Case Study of Ex-situ Biological Treatment of Perchlorate-contaminated Groundwater

Groundwater in certain areas at Longhorn Army Ammunition Plant (LHAAP) (Texas) contains volatile organic compounds (VOCs) and perchlorate from past operations at the site. Groundwater from a Burning Ground and Landfill is currently being remediated by pumping the water from an interceptor collection trench system to the surface, removing VOCs and metals in an ex-situ treatment process, and disc...

Comparative Demonstration of Active and Semi- Passive In Situ Bioremediation Approaches for Perchlorate-Impacted Groundwater at Longhorn Army Ammunitions Plant

Rodent sperm analysis in field-based ecological risk assessment: pilot study at Ravenna army ammunition plant, Ravenna, Ohio.

Ecological risk assessment (ERA) guidance recommends that field-truthing efforts proceed when modeled hazard quotients (HQs) suggest that toxicological effects are occurring to site receptors. To date, no field methods have been proposed by the regulatory community that can lead to definitive determinations of acceptable or unacceptable risk for birds and mammals, the two terrestrial classes of...

ERDC/CERL TR-08-3, Anaerobic Treatment of Wastewaters Containing Perchlorate from Munitions Handling and Production

Perchlorate, an oxidizer routinely used in solid rocket motors, is easily washed out of old motors. The washout operation, however, leads to wastewater containing perchlorate. Royal Demolition Explosive (RDX), a major component of military high explosives, is transferred to Army industrial wastewaters during assembly of new munitions and during demilitarization of old munitions. New high explos...

Anaerobic treatment of army ammunition production wastewater containing perchlorate and RDX.

Perchlorate is an oxidizer that has been routinely used in solid rocket motors by the Department of Defense and National Aeronautics and Space Administration. Royal Demolition Explosive (RDX) is a major component of military high explosives and is used in a wide variety of munitions. Perchlorate bearing wastewater typically results from production of solid rocket motors, while RDX is transferre...
