Sweden is a country with a lot of coastal area and has groundwater as the major fresh water source. Therefore, it has become extremely important to monitor any drilled holes for potential saltwater intrusion. For over 20 years, drillers in Sweden have been searching for geothermal heat to use as an alternative energy source. In… Continue Reading »
The CMT System (Since 1999) CMT offers in-field design flexibility, low cost and is easy to install. The number of monitoring ports, port locations, install depths, and monitoring strategy, can all be accommodated and designed right in the field. The single tube offers effective sealing.The 7-Channel is 1.7″ (43 mm) and the 3-Channel is 1.1″… Continue Reading »
Stainless Steel Bladder Pumps can lift from depths of 500 ft (150 m) below grade, and PVC models from 100 ft (30 m). Samples can be obtained from greater depths using a drop tube assembly. This places the screened filter intake of the pump as deep as necessary to access the sample zone required. Easily installed without tools on existing pumps,… Continue Reading »

WYG was given the task of developing a cost effective means to isolate and reliably sample groundwater quality, and obtain hydraulic head data from various zones, in a complex geological setting, to give detailed vertical gradients. The investigation… Continue Reading »
Before the advent of pressure transducers with data loggers, field technicians and drilling contractors were relegated to hours, or even days on site during conventional pumping tests, continuously monitoring water level fluctuations in a vast array of observation wells. Often requiring running from well to well, readings were taken by hand with Water Level Meters. This was… Continue Reading »
Researchers from the Biology Department at Villanova University in Pennsylvania, USA, and the Zoology Department at Oregon State are studying the growth and survival effects of intertidal elevation and wave shock on purple sea urchins (Strongylocentrotus purpuratus). The study is being carried out at seven locations on the west coast of North America: Mabens Beach,… Continue Reading »
