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.

The program includes the use of the Solinst LTC Levelogger Junior to monitor changes in water level, temperature, and conductivity in rivers and streams. Conductivity readings provide a general indication of the water quality, while the water level and temperature readings may be used to provide background information when any spikes or significant changes in conductivity readings are noticed.

An aquifer in Central Ontario became contaminated with BTEX and PCH F1 (Petroleum Hydrocarbons – Fraction #1i) from leaking underground infrastructure linked to a gas station. The groundwater in the aquifer flows between 3 -13 meters a year, as such, a voluntary cleanup of the aquifer was initiated to remediate the plume source, and to stop the dissolved plume phase from moving off-site.

The new Biofoul Screen is designed to fit onto the sensor end of any Levelogger model. The natural anti-fouling characteristics of copper protects the sensors from build-up of unwanted microorganisms, plants, algae, or organisms such as barnacles or mussels, which could affect the reliability of the sensor readings.
