Geophysical Measurements

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 and software for recording and analyzing measurements of the geophysical properties of wells and boreholes.

Sand Shaker

Geotech Sand Shaker

Grain-size analysis is used for studying soils, sediments, sands, or rock by determining size, distribution, and proportion of selected particles.

The Geotech Sand Shaker is a manual sieve kit designed to provide reliable grain size analysis. It features 20 stainless steel screens ranging in size from US Sieve No. 4 to 270. The sample is placed into the top of five clear acrylic cylinders, shaken to distribute particles, and volumetric percentages are indicated on the Shaker frame for quick and accurate gradation.
