The voluntary monitoring program for tritium releases, while providing limited data from some plants, is far from sufficient for protection of groundwater as a critical safe future drinking water source. Voluntary monitoring provides no tools for accountability or to drive the investigation, remediation of groundwater quickly to prevent off site migration of contaminants.
Unquestionably, an enforceable GW standard for tritium and other and additional precautionary action levels must be in place close to the plant footprint, and at other locations on-site. There must be mandatory sufficient frequency of monitoring and number of monitoring wells based on local hydrology, positioning of coolant pipes. Coolant pipes must be above ground and in secondary/tertiary containment so that they may be visually inspected frequently for potential failure points.
