The AquaVISION Colloidal Borescope measures groundwater velocity, direction and particle size in real-time. It accomplishes these difficult tasks by using proprietary hardware and AquaLITE software. The AquaVISION Colloidal Borescope System accurately determines groundwater velocity, flow direction and particle sizes at depth-specific intervals. The AquaVISION Colloidal Borescope System yields thousands of data points per minute for hours of statistically assured data.

- Company Information
AquaVISION’s Colloidal Borescope System provides a direct means of accurately determining groundwater flow direction and velocity. The Borescope measurement technique uses existing monitoring wells or developed borings for assessment and thus avoids the cost of additional wells and piezometers.
• Assessing groundwater capture zones
• Planning locations for monitoring recovery wells, and injection wells
• Accurately calibrating groundwater models
• Excellent alternative to slug tests and pump tests
• Tidal influences
• Industrial hydrology
• Gathering evidence for groundwater contamination litigations
• Can observe flow at the pore scale which measure velocities ranging

Formed in 1956, Geotech transitioned from a specialty machine shop to an environmental equipment manufacturer in 1978 when invited by the United States Geological Survey (USGS) to partner with them in developing products and technologies for the emerging U.S. Trace Metals Analysis Program.
As a result of this partnership, the bladder pumps, peristaltic pumps, 0.45-micron sampling filters, and filter holders developed by Geotech for the program became the groundwater industry standards.
Geotech rounded out already-extensive product lines by acquiring three outstanding companies: Oil Recovery Systems (ORS) in 1997, Keck Instruments, Inc. in 1999, and the Marschalk Corporation in 2005. Coupled with ongoing product research and development, Geotech today offers the most extensive line of equipment in the environmental field.
In addition to its 125,000 square-foot Denver-based manufacturing plant and corporate headquarters, Geotech now operates service centers in six other states, plus a European Sales Center in Barcelona, Spain and a representative office in Beijing, China. Geotech equipment meets environmental challenges on every continent!
