Plant response to aqueous effluents derived from in-situ fossil-fuel processing. Part III. Three grass species and their response to Omega 9 and to five produced retort waters: oil shale, tar sands and underground coal gasification. [Basin wildrye; western wheatgrass; alkali sacaton]
In situ produced waters collected from retorting oil shale and tar sands to produce oil and in-situ coal gasification to produce gas were tested for their effect on plant growth. Three native grass plant species were utilized for monitoring growth response. Root weight, shoot weight, total dry weight, leaf area, root/shoot ratio and shoot/leaf area ratio were parameters measured. All experiments were conducted under greenhouse conditions using hydroponic techniques and commercial grade perlite as support systems. Measurements were collected after a 10-week growth period. The hypothesis tested was, there is a difference between produced waters diluted by ground water and those where dilution is non-existent and their effect on plant growth. Results indicated that retort water diluted by ground water has a less toxic effect on plant species tested.
