Description:

REPORTING PERIOD: Apr. 24, 2000 – Jul. 7, 2000

  1. Testing continued on the 10 tank-bottom sludges to characterize chemical properties. Samples were digested and analyzed for heavy metals. Sludge samples were directly analyzed for hexane-extractable materials.

  2. Testing continued on the 4 roadbase mixtures.

 

PLANNED ACTIVITIES FOR NEXT QUARTER:

  1. Subject the roadbase test specimens to freeze-thaw testing.

  2. Finalize environmental analyses on road base test specimens.
