Abstract
The report gives results of an assessment of the toxicity treatability of wastewaters from eight steelmaking subcategories, all considered assessable under the somewhat low production levels of the study period. Tests were conducted using prescribed procedures for conventional water contaminants, toxic organics, and static bioassay. Samples were collected before and after units of the wastewater treatment systems. All tests were done under the auspices of a quality assurance program. Efforts were made to ensure representativeness of all samples; e.g., if the production facilities were operating only one turn, samples were collected only during that turn. Results show the relative toxicity and variability of wastewaters from the different manufacturing subcategories and the reductions in toxicity. Relationships between pollutant content and toxicity are examined with cognizance of the possible site uniqueness of the data.

Contents Notes
"The full report documents an assessment of the biotoxicity reduction and concurrent pollutant reduction achieved by 24 wastewater treatment systems serving 8 iron and steelmaking process subcategories. Sampling programs, designed to provide measurements before and after successive unit treatment processes, were conducted at seven plants. Chemical analyses were performed for conventional, priority, and regulated pollutants. Additional tests were made to identify other potentially harmful metals and organics. Bioassays were performed using both minnows and daphnia. The results of chemical analyses were compared with toxic concentration limits in relating biotoxicity to pollutant concentrations. Cokemaking wastewater treatment systems tested that employed single stage bioreaction yielded more highly toxic effluents than did the physical/ chemical treatment. Ironmaking waters treated to below 2,000 fjg/L total metals were nontoxic to minnows. Steelmaking waters after flocculation and clarification retained toxic levels of lead and zinc. Hot forming wastewaters showed low biotoxicity where metal concentrations were reduced sufficiently. Cold forming wastewaters showed varying biotoxicities associated with the levels of oil and grease, organics, and metals remaining after treatment. Treatment studies for hot coating and pickling wastewaters showed good reduction of biotoxicity."
