A pilot injection of tritiated water has been made into the groundwater in a study of the groundwater and surface hydrology of foothill areas in the Sierra Nevada in Placer County. Results from the initial trials confirm the movement of groundwater in the jointed rock formations as predicted from groundwater contour maps. The movement and subsequent detection of the tritiated water over distances of hundreds of feet indicates that the joint system is well connected.
