Las Cruces, New Mexico<\/strong><\/p>\n Soil Remediation at the 600 Area Off-Site Pile<\/strong><\/p>\n The NASA White Sands Test Facility (WSTF) is crucial for supporting space exploration and technology development. Located in New Mexico, it provides a controlled environment for testing and evaluating spacecraft, propulsion systems, and other aerospace technologies. The facility is instrumental in conducting critical tests such as engine firings, thermal and environmental testing, and materials research. Its role in ensuring the safety, reliability, and performance of spacecraft and systems makes it a key asset in NASA\u2019s mission to explore space and advance scientific knowledge. Unfortunately, past practices associated with the execution of its mission adversely impacted soil and groundwater resources.\u00a0<\/p>\n From June 1974 to December 1979, sludge and soil removed from a domestic and industrial wastewater lagoon was stockpiled on Bureau of Land Management land west of the NASA White Sands Test Facility (WSTF) facility boundary, less than a mile from the lagoon. When accumulation of material ceased, the sludge\/soil debris pile lay dormant with no boundary identification. In 1993, during a Resource Conservation and Recovery Act field investigation the debris pile was identified and reported to the New Mexico Environment Department (NMED) and designated as Solid Waste Management Unit (SWMU) 16.<\/p>\n Initial investigations were completed at SWMU 16 in 2015 and 2018 to characterize the stockpiled sludge\/soil and native soils beneath the stockpile to a depth of 30 feet. Analysis of soil sample data indicated the contaminants in the pile posed a risk to human health and the environment due to identified concentrations of nitrates, metals, volatile and semi-volatile organics, pesticides, polychlorinated biphenyls, and dioxins and furans. The NMED agreed to the removal and off-site disposal of New Mexico Special Waste<\/em> in 2021.<\/p>\n Excavation of the stockpile and the upper 6 inches of native soil was completed in January 2024. Excavation of native\u00a0soils extended approximately 10 ft beyond the extent of the pile. A total of 1,072.7 tons of sludge and soil were disposed at the Corralitos Landfill.\u00a0 In February 2024, confirmatory soil samples were collected from 38 locations on a 30-foot grid established across SWMU 16, encompassing the location of the removed stockpile and all areas potentially affected by site operations. These samples were submitted for laboratory chemical analyses to determine if NASA had met is remedial objectives and eliminated the exposure risk to human health and the environment.<\/p>\n The results showed that NASA had succeeded. The site was restored.\u00a0 Results of soil sample analyses did not identify site contaminants remain at the site, and a risk assessment did not identify elevated risk to receptors or to groundwater beneath the site. NASA concluded that site contaminants have been removed, the risk to human health and the environment are below regulatory targets. NASA recommended a change in site status from \u201cRequiring Corrective Action\u201d to \u201cCorrective Action Complete without Controls\u201d. The report of results is currently under review by the NMED.<\/p>\n Visit nasa.gov\/emd<\/a> to learn more about NASA\u2019s Environmental Management Division (EMD)!<\/p>\n Powered by WPeMatico<\/a><\/small><\/p>\n Get The Details…<\/a> NASA White Sands Test Facility Las Cruces, New Mexico Soil Remediation at the 600 Area Off-Site Pile Origins of the 600 Area Off-Site Pile The NASA White Sands Test Facility (WSTF) is crucial for supporting space exploration and technology development.
