Colloidal Borescope

The Colloidal Borescope provides services and instrumentation that measure groundwater velocity, direction and particle size all in real time. They accomplish these difficult tasks by using proprietary hardware and software known as the “Colloidal Borescope System.”

The Colloidal Borescope System was developed by a team of research scientists to accurately determine groundwater velocity, direction and particle size in real time. Current down hole technologies only allow for a few groundwater flow measurements per day. The Colloidal Borescope System yields thousands of data points per minute for hours of statistically assured data.

Benefits

The Colloidal Borescope System provides a direct means of accurately determining groundwater flow direction and velocity. The Borescope measurement technique uses existing monitoring wells for assessment and thus avoids the cost of additional wells and piezometers.

Applications

• Assessing groundwater capture zones
• Planning locations for monitoring and extraction wells
• Accurately calibrating groundwater models
• Tidal influences
• Industrial hydrology
• Gathering evidence for groundwater contamination litigations
• Can observe flow at the pore scale which measure velocities ranging from 0 to 25 mm/sec
• Evaluate “cross-hole” hydraulic connections
