The results of the environmental monitoring program conducted at Site A/Plot M in the Palos Park area for CY 1985 are presented. The monitoring program is the ongoing remedial action that resulted from the radiological characterization of the site. The current program consists of sample collection and analysis of air, surface and subsurface water, and bottom sediment to determine the migration pathway of water from the burial ground (Plot M) to the wells, establish if other buried radionuclides have migrated, and otherwise characterize the radiological environment of the area. Earlier studies had determined that hydrogen-3 (as tritiated water) migrated from the burial ground and was detected in two nearby hand-pumped picnic wells. Hydrogen-3 in the Red Gate Woods picnic well continued to show the same pattern of elevated levels in the winter and low concentrations in the summer, but the magnitude of the winter peak (2.5 nCi/L) was significantly less than in earlier years. Tritiated water continues to be monitored at a number of wells, boreholes, and surface streams where it has been detected in the past. For many years it was the only radionuclide found to have migrated until recent measurements indicated the presence of strontium-90 in borehole water next to Plot M. The presence of the strontium-90 is an indicator of migration of radionuclides other than tritiated water from the Plot. However, the results of the program indicates that the radioactivity remaining at Site A/Plot M does not endanger the health or safety of the public visiting the site or those living in the vicinity.
