9/26/91 test 'Volatile Organics' Analysis of Alum Sludge by Resource Analysts, Inc, Subsidiary of MILLIPORE.

This study found concentration of 37 Volatile Organics below EPA'sdetection limit.

9/26/91 Test of "Alum Sludge" Using EPA Test Methods for the Evaluation of Solid Waste.

Section 7.1 Ignitability Sample could not be ignited in 30 seconds.

Section 7.2 Corrosivity

(9/23/91) "A 25 g portion of the nonaqueous sample was added to 25 mL deionized water. The mixture was stirred occassionally over the course of 30 minutes, then allowed to stand undisturbed for one hour. At this point, the pH of the supernatant was 2.18

Section 7.3 Reactivity. 25 mg sample added to 25 mL water. partial suspension which settled, forming no gas. No evidence of any reaction was observed.
