Quick facts. 2000: In September, one source area (Site 1) was closed after vadose zone contamination was reduced to a level where groundwater would not be impacted above the maximum contaminant level (MCL). Plant 42 has been around for a long time. Welcome to the United States Air Force. In October, the USAF submitted to the agencies a Shallow Groundwater Zone Remedial Process Optimization (SGZ RPO) Work Plan. The work plan included installation of new monitor wells to further characterize the shallow groundwater zone. 1983: The TIAA Superfund site (which includes the APF-44 project area) was added to the NPL on September 8, 1983. In 1996 and 1997, the USAF produced a new ROD that specified SVE treatment of VOC contaminated soils at AFP-44. In-situ pilot studies were continued to evaluate the use of potassium permanganate (KMnO4) to degrade VOCs in groundwater beneath site DP-02 (FACO Landfill) and site DP-03 (Inactive Drainage Channel Disposal Pits). In 1981, investigations of groundwater quality around Tucson International Airport revealed a number of wells that pumped water contaminated with trichloroethylene. Hughes Aircraft Company Air Force Plant 44, RCRA Appeal No. LACKLAND AIR FORCE BASE, Texas -- The Air Force is always on the lookout for new ways to reduce, reuse and recycle. Get the Fire Dept latest news, contact info, logo, patch, photo, map, fire equipement, statistics, type of firefighters. 1994 - 1997: A feasibility study (FS) for soil remediation was completed. 2012: The AF entered into a Performance Based Remediation initiative to maximize the effectiveness of remedial actions at AFP-44. Revised on: August 28, 2020 - 2:37pm . Softshell jackets, parka's, sweaters, hoodies, winterjassen & veel meer. These facilities were designed so that they would build aircraft parts for the government. USGS participation in field activities at AFP 44 enables it to provide appropriate technical assistance to the Air Force and provide accurate information to the public and policy makers. The contracting team was tasked with performing expedited field investigations and treatability studies to provide the AF with alternative remedial. Below are publications associated with this project. Contamination of the aquifer with organic solvents and stabilizers in the area surrounding the Tucson International Airport has been an issue of public concern since being discovered in 1981. The USAF submitted to the agencies a work plan for a Phase II focused RI of the 1,4-dioxane. 2009: In September 2009, the advanced oxidation treatment system became fully operational. Arizona, United States Valencia Armory (7.8 mi.) 1976: The State of Arizona closed a well at AFP-44 due to high levels of chromium. It covers 2,900 acres (95% government-owned) and 2.1 million square feet (51% government-owned, including the manufacturing … The primary objective of this project is to provide technical assistance to the Aeronautical Systems Center (ASC) of the U.S. Air Force for their oversight responsibilities for remediation activities being conducted by contractors at Air Force Plant 44. Air Force Plant 42 is a music company based out of 800 Independence Ave Sw, Washington, DC, United States. From 1994 to 1996, Dual-Phase Extraction (DPE) systems were installed to treat VOC-contaminated soils and groundwater. Minimal changes occurred at the perimeter of the plume, suggesting that operation of the reclamation well field has been successful at containing the spread of the plume. | Heren, dames en kinderen 1991 - 1992: An remedial investigation (RI) of soil contamination at AFP-44 was conducted with supplemental field work being completed in 1993 and 1995. Most of the facilities are owned by private contractors and serve as a manufacturing plant for aircraft used by the United States and their allies' militaries. Military aircraft have been manufactured here since 1942. Participants . This HiPOx™ (High Pressure Oxidation) treatment system was designed to remove 1,4-dioxane, but also effectively removes VOCs  This new system replaced the air-stripping treatment system that was built in 1987. Results of this evaluation and additional studies would be presented in the focused FS for 1,4-dioxane. Waste disposal practices led to widespread soil and groundwater contamination at the site. In response to community concerns, the comment period was extended to 12/4/2014. In the 34 wells sampled, 1,4-dioxane concentrations ranged from non-detect in 10 wells to a high of 11 ppb in 2 wells (Figure 1). 2013: The AF continued to investigate offsite 1,4-dioxane groundwater contamination north of AFP-44 (North of Los Reales Road). The AF completed work plans to perform expedited field investigations and treatability studies for alternative remedial actions at AFP-44, which were evaluated and approved by ADEQ and EPA.
