| Abstract | Results of leaching tests are summarized in the report. Using the EPA EP (extraction procedure) acetic acid leaching test, it was determined that leachate levels for arsenic, lead, cadmium, barium, silver and chromium from slag samples were compatible with the results of total analyses (bases on two acid digestion techniques). However, the proportions removed were generally higher for cadmium and lead than the other four metals. In comparing the results of the EP toxicity test with data from the EP toxicity test without pH adjustment, the ASTM distilled water extraction procedure, and a synthetic rainwater leach, it was concluded that the initial pH, not the affinity of acetic acid for lead and cadmium, is the dominant factor in determining levels of metals extracted. |
