Kent’s presentation focused on a small scale (~10 m x 10 m plot) study in which he developed three distinct site conceptual models for a fractured bedrock site, using different depth-discrete hydraulic and tracer transport measurements. Continue Reading »
Gary presented a time-line of key developments in groundwater monitoring technologies, from the introduction of conventional monitoring wells in the 1950’s, to the late 1970’s when the first multilevel groundwater monitoring systems were produced. Continue Reading »
While completing his Ph.D. at the University of Waterloo, Patryk designed packer testing equipment to be used for conducting hydraulic tests in fractured rock, for contaminant transport studies. Continue Reading »
Richard provided a very interesting presentation on the work he is doing at the Diavik Diamond Mine in the Northwest Territories. The project aims to help better understand acid mine drainage in cold climates. Continue Reading »
Jessica’s presentation focused on the field work that she has completed at the site. The goal of her research was to use a high-resolution method of measuring head at depth-discrete zones in order to calculate vertical gradients across the site. These vertical gradients were used to delineate hydrogeologic units in the subsurface. Continue Reading »
At the close of the 2013 Solinst Symposium, a round-table was held with the attendees and guest speakers. A common theme in the discussions was education. Continue Reading »
Because the goal of Leveloggers is to provide fluctuations in water pressure only, their data must be compensated for barometric effects. In order to achieve this, barometric pressure must be subtracted from the Levelogger readings to give actual water level data. Continue Reading »
On November 7, 2013, we held our fourth “Solinst Symposium” here at our facility in Georgetown, Ontario, Canada. The Symposium theme was “High Resolution, Depth-Discrete Groundwater Monitoring – Benefits & Importance”. Continue Reading »
Have you noticed a difference in raw water level (pressure) readings when comparing data recorded by the latest Levelogger Edge line versus previous models? Find out why. Continue Reading »
The Model 425 Discrete Interval Sampler is a no-purge instrument that allows groundwater sampling from specific depths, without mixing of water from different levels. The stainless steel sampler is pressurized before being lowered to prevent water from entering until the desired zone is reached, pressure is released and the sampler fills with water from the discrete zone.
