Geophysical Measurement Rentals
The quality of groundwater is highly variable and groundwater contamination may be caused by man-made or natural sources. Integration of borehole-geophysics logging with water-quality sampling provides a more complete picture, whether the objective is to develop a water-supply well or remediate a contaminated aquifer.
Wells are the access points to the groundwater system, and knowledge of their construction and condition are important whether they are being used for groundwater supply, monitoring, or remediation. The location and condition of casing and screen can be rapidly evaluated with geophysical logging.
Geotech offers instruments for recording and analyzing measurements of the geophysical properties of wells and boreholes.

Laval SC-350 Borehole Camera
The Laval SC-350 is a lightweight, portable downwell camera system for inspecting water wells and boreholes from 2 inches (5 cm) to 10 inches (25 cm) in diameter. The compact SC-166 camera runs on 350 feet (107 m) of Kevlar-reinforced coaxial cable from a hand-operated winch, with an on-screen depth counter. The rental system includes a 9 inch monitor with recording, and a tripod with depth encoder is also available to rent.
