The accelerator beam delivered to the beam dumps and elsewhere causes radiation that could activate nearby soil and groundwater. Jefferson Lab has performed preoperational monitoring to establish an environmental baseline. Groundwater Monitoring Well Data have been submitted to the DEQ by the tenth of the month following each reporting period. Sample protocols are shown in Appendix 6315-T1 Ionizing Radiation Monitoring Procedures . Well locations monitored are provided in Chapter 6711 Environmental Monitoring .
Sample protocols are the same as for preoperational monitoring.
Well locations for long term monitoring are shown in Chapter 6711 Environmental Monitoring . Since pump discharges in accelerator areas could contain low levels of induced radioactivity, effluent water will be periodically collected from the accelerator and end station dewatering sumps and analyzed for the same radioactive constituents as the groundwater samples. Additional sumps and surface water bodies are monitored periodically. The data are compared to the on-site groundwater limits and operations are managed to ensure that any offsite release is within applicable regulations and conditions. Refer to Appendix 6315-T1 Ionizing Radiation Monitoring Procedures for more information.
