COLLOIDAL BORESCOPE FLOWMETER (CBFM)
The Colloidal Borescope was developed to accurately determine horizontal groundwater velocity and direction in wells and open boreholes. Acquiring multiple real-time tracking measurements of colloids inherent in groundwater provides statistically-assured data. The resulting data-set is a compilation of thousands of tracked vectors at specific depths. Utilizing existing monitoring wells for test locations saves costs and eliminates the need for additional new piezometers.
