Hexavalent Chromium Reduction Pretreatment Process Evaluation, Randolph AFB, Texas

Abstract

The scope of this survey was to evaluate an experimental in-situ chromium reduction process. The objective was to determine if base personnel could safely and effectively treat chromium waste so that it would no longer be considered a hazardous waste. Recommendations include: (1) Obtain approval from TWC to perform the pretreatment process; (2) Perform cyanide removal on each drum of waste; (3) Do not mix the precipitate back into solution before discharging the wastewater to the sanitary sewer; (4) Sample and analyze the sludge for hexavalent chromium; (5) Sample an appropriate percentage of the drums to ensure the process routinely works; (6) Pretreatment personnel should always wear protective clothing.
