A review is presented on sources of solid wastes generated from fixed bed gasification processes, and suggestions are made for acceptable disposal alternatives. Samples of fixed bed coal gasification solid wastes from the Grand Forks Energy Technology Center's slagging gasifier, and the Morgantown Energy Technology Center's low Btu stirred fixed bed gasifier were sieved into discrete particle size ranges, and each particle size range was subjected to leaching in accord with EPA-''EP'' and ASTM-A procedures. Each derived leachate sample was analyzed for key heavy metals. In addition, AMES testing for potential mutagenicity, and acute toxicity testing via utilization of Daphnia bioassay procedures was conducted on smallest and largest size fractions of the sieved samples. Results of bioassay procedures are not complete at this time, however, data that has been developed to date indicates that potential toxicities exist based on Daphnia evaluations via the LC-50 test using GFETC solid wastes leached via the ASTM-A procedures. Results of such tests are not now currently part of RCRA regulations, but have been considered in draft versions of these regulations. Daphnia testing using leachates developed via the ASTM-A (distilled water) procedure and the EPA-''EP'' (acetic acid) procedure are not comparable. Heavy metal data indicates that no legislative difficulties should exist vis-a-vis RCRA regulations; however, should secondary drinking water standards be incorporated into RCRA regulations, the GFETC solid wastes may prove administratively ''toxic'' due to excessive iron levels in developed leachates.
