Accurate data on the long-term performance of the radioactive wastes in disposal systems is becoming a necessity in part because of restrictive federal and state regulations which are being promulgated. A method which provides data on the performance of buried radioactive waste forms is comprised of lysimeters. They are ideal instruments for obtaining actual field test data because when properly designed and operated they can be used to isolate and then study soil/waste systems under actual environmental conditions. The complexity of interactions under such conditions can never be completely duplicated by standard laboratory testing. This paper provides data from two instrumented, operational lysimeter arrays containing waste forms fabricated with highly loaded exchange resin materials. The lysimeters have been in operation for three years and provide both meteorological data and radionuclide content of percolating water. This paper provides data obtained from the lysimeters and discusses how these data can be used as a database for input into codes used to verify performance of buried radioactive waste forms.
