Pine Bluff Arsenal, Arkansas

CBARR operators are conducting air monitoring and on-site soil sampling at Pine Bluff Arsenal in Arkansas. Review of historical photographs and records show that the two locations have a high probability of containing chemical warfare material. Intrusive operations to date have uncovered numerous mortar rounds, projectiles and chemical agent identification sets that are being stored in an interim holding facility for future assessment.

U.S. Army Pueblo Chemical Depot, Colorado

The U.S. Army Pueblo Chemical Depot (PCD) in Colorado spans 23,000 acres and has a primary mission of storing one of the last two remaining chemical weapons stockpiles in the United States. CBARR has provided a range of capabilities to PCD and the chemical weapons destruction pilot plant which has been constructed to destroy the stockpile. As part of a Resource Conservation and Recovery Act facility investigation, CBARR is actively supporting operations in two solid waste management units that are suspected of containing potential chemical warfare material. The team provides automated continuous air monitoring systems that ensure the safety of personnel and the environment. Additionally, CBARR’s fixed and mobile laboratories are providing critical analysis of air, water and soil samples to determine the presence of chemical agent and agent breakdown products.

Spring Valley, Washington D.C.

The Spring Valley Formerly Used Defense Site is a 650-acre plot in northwest Washington D.C. that used to be the site of United States government chemical agent testing. Today, the site encompasses 1,600 private properties, including several embassies and foreign properties, as well as the American University and Wesley Seminary. CBARR has been involved in destruction and remediation efforts at this site since chemical agent was discovered under a residential property in 1996. This year, CBARR completed intrusive sampling in one residence to determine whether chemical agent, chemical agent breakdown products or volatile organic compounds existed below the home’s foundation. The project team collected more than 100 samples from the residence for analysis.
