]Solid Waste Management Unit B-29, February 2005
Chronology of Actions/Investigations
| Year | Month | Action/Results | Action Performed By | Project Number |
| Unknown | Unknown | Old quarry area was used for disposal of miscellaneous solid waste, munitions, and construction debris. | CSSA | NA |
| 1993 | September | A decayed drum of nickel penetrate was observed during the field survey. | Parsons ES | Order 71 |
| 1996 | February | Work Plan for B-29 investigation submitted. | Parsons ES | RL17 |
| March - April | EM geophysical survey performed on March 12 and April 2. Three geophysical anomalies found, all caused by waste management activities. | Parsons ES | RL17 | |
| March - April | Collected 3 surface soil samples (SS1-SS3) on March 13, analyzed for VOCs, SVOCs, explosives and metals. Analytical results are currently in question due to ITS Laboratory practices. | Parsons ES ITS | RL17 | |
| August | Completed 6 soil borings (SB1-SB6) on August 28, 29 and 30, and sampled for VOCs, SVOCs explosives, and metals. Analytical results are currently in question due to ITS Laboratory practices. | Parsons ES CoreTerra ITS | RL17 | |
| 1997 | May | Resampled SB1 on May 15 for VOCs only. Analytical results are currently in question due to ITS Laboratory practices. | Parsons ES CoreTerra ITS | RL17 |
| 1999 | April | EPA memorandum indicated analytical results obtained from ITS are not usable. | EPA | NA |
| November | Submitted work plan for resampling to replace analytical chemistry data generated by ITS Laboratory. | Parsons ES | NA | |
| 2000 | March | Collected 3 surface soil samples (SS1-3) for Rework, analyzed for VOCs, SVOCs, metals and explosives. Advanced 6 soil borings (SB1-6) for Rework and collected 14 soil/rock samples for VOCs, SVOCs, metals and explosives (7 samples) and explosives (7 samples) and SVOCs, copper, zinc, lead and explosives (7 samples) analysis. | Parsons ES APPL, Inc. O’Brien & Gere Data Chem | Rework |
| 2002 | August | Parsons | RL17 | |
| 2003 | December | Parsons | TO19 | |
| 2004 | January | Began slit trenching the side walls of the quarry. Found burned debris mixed in with metal and small caliber projectiles. Encountered seven 75 mm projectiles and frag bomb sleeves, work stopped until EOD personnel can be on site. Soils excavated with EOD personnel on site to inspect any items of concern found. Items found were banding material, ammo cans, one 55 gal. drum filled with 50 cal. casings, top component to grenades, railroad ties, and 20 mm casings. Nothing was fused or contained a propellant. No UXO items of concern found. Waste characterization and closure samples collected. | Parsons | TO19 |
| April - June | Excavated soil hauled off-post to Covel Gardens. Hazardous soil piles mixed with phosphate. Confirmation samples collected. | Parsons | TO19 | |
| 2005 | April | Final SWMU B-29 RCRA Facility Investigation Closure Report submitted. | Parsons | TO19 |
| 2008 | February | TCEQ | NA |
