List of Projects

Acids Areas

Used for the manufacturing of nitric and sulfuric acids used in various stages of the manufacture of TNT and pentolite

  • Acid Area #1 – central portion of PBOW, south of the Garage and Maintenance Area
  • Acid Area #2 – westernmost portion of PBOW, south of Maintenance Road and east of Patrol Road, northwest of Pipe Creek
  • Acid Area #3 – northwestern portion of PBOW along Ransom Road north of Maintenance Road

Ash Pits and Power Plants

The Ash Pits were disposal areas for fly ash generated from the burning of coal at on-site Power Plants

  • Ash Pit #1/Power Station #1 – south of Maintenance Road and north of railroad tracks and the power house building
  • Ash Pit #2/Power Station #2 – west of Campbell Street, across the street from the power station
  • Ash Pit #3/Power Station #3 – west of Ransom Road and south of Maintenance Road

Burn Grounds

Used for the disposal of explosive manufacturing wastes and out-of-specification ordnance

  • Reservoir #2 – northwestern portion of PBOW
  • G-8 – southwestern portion of PBOW near the intersection of Campbell Street and Patrol Road
  • Taylor Road – southeast of Taylor Road and east of Ransom Road
  • Snake Road – southern portion of PBOW, north of intersection of West Scheid and Snake Roads
  • Fox Road – northeastern portion of PBOW north of Fox Road

Garage and Maintenance Area

Used for the general maintenance of equipment and vehicles; located in the central portion of PBOW along Maintenance Road

Pentolite Area

Used for the production of pentolite; located in the north-central portion of PBOW within the boundaries of Ransom Road on the west, Pentolite Road on the south, and Patrol Road on the north and east

Rail Car Unloading Area/Sellite Area

The Rail Car Unloading Area is near the Garage and Maintenance Area on the north side of Maintenance Road between Ransom and Taylor Roads and was used to unload toluene and other chemicals from rail cars; the Sellite Area is west of the Rail Car Unloading Area and was used for the production and storage of sellite used for the TNT washing process

Red Water Ponds

Discharge areas for process waste water resulting from one of the final purification steps in the production of TNT; named due to color of water

  • West Area – two ponds on west side of PBOW; contained wastes from TNT Area C
  • Pentolite Road – north central portion of PBOW; contained wastes from TNT Areas A and B

Sitewide Ground Water

Potential for ground-water contamination

TNT Areas

Location where Operations were housed for the manufacture of trinitrotoluene (TNT) and dinitrotoluene (DNT); each TNT Area incorporated Underground Wastewater Flumes, Toluene Tank Areas, Red Water Ponds, and Wastewater Treatment Plants

  • TNT Area A – 113 acres on the east side of Plum Brook Ordnance Works (PBOW)
  • TNT Area B – 48 acres in the southern portion of PBOW
  • TNT Area C – 113 acres on the west side of PBOW

TNT Rail Car Loading Areas

Used to load rail cars with TNT for shipment from the site to storage areas on the site; suspected at each TNT Area

Toluene Tank Areas

Each TNT area had two above-ground storage tanks

  • 255 & 265/TNT Area A – 'Upper Toluene Tanks,' west of TNT Area A and Short Cut Road and south of Maintenance Road
  • 425 & 435/TNT Area B – 'Middle Toluene Tanks,' northwest of TNT Area B near Taylor Road
  • 645 & 655/TNT Area C – 'Lower Toluene Tanks,' near intersection of Patrol Road and Taylor Road; Tank 645 was moved by NASA to the former Pentolite Area

Underground Wastewater Flumes

Used to carry liquid and solid wastes that accumulated in catch basins located at the wash houses located in:

  • TNT Area A – waste to Pentolite Road Red Water Ponds
  • TNT Area B – waste to Pentolite Road Red Water Ponds
  • TNT Area C – waste to West Area Red Water Ponds

Waste Lagoons

Settling basins in which wastewater was disposed; located north of Pentolite Road

Wastewater Treatment Plants

Each TNT Area contained a wastewater treatment plant used to treat the 'red water,' wastewater from the process of producing TNT

  • Wastewater Treatment Plant (WWTP) 1 – for TNT Area A
  • WWTP 2 – for TNT Area B
  • WWTP 3 – for TNT Area C
