Over the last two years, researchers in the Department of Civil and Environmental Engineering at the University of Louisville have been conducting an extensive assessment on a stream in Oldham County, Kentucky. The stream, which can be classified as “headwater”, has a drainage area of about 2.8 square miles (7.2 square kilometers) at the upstream… Continue Reading »
The Solinst RRL Gold Radio Telemetry System offers a very simple and inexpensive method of local telemetry. The wireless system is designed to collect real-time water level data, logged by up to four Solinst Leveloggers and send it via shortdistance radio to your computer. The RRL Gold is excellent for small, closed loop networks, such as mine… Continue Reading »
In a town in the Piedmont physiographic province, in the mid Atlantic, a proposed water supply well was contaminated with methyl tert butyl ether (MTBE). The well is located down gradient of several gas service stations with multiple known sources of MTBE. As such, a remedial effort was required by Virginia Department of Environmental Quality… Continue Reading »
Automatic Barometric Compensation Submersed Leveloggers measure total or absolute pressure (water column equivalent + barometric pressure). In order to accurately determine the true changes in water level only, barometric pressure fluctuations must be taken into account. The simplest method to accomplish this is by the use of a Barologger suspended above high water level in one well… Continue Reading »
As the Olympic torch is passed from our hands in Canada, huge efforts are underway for the 2012 Summer Olympics set to take place in London, England. In preparation for the games, a new Olympic Park is being constructed in Stratford, East London. In the works since 2005, the Park spans 500 acres and features… Continue Reading »
Model 464 Easy-to-Use Electronic Pump Control Unit The New Model 464 Pump Control Unit is designed to work with Solinst Pneumatic Pumps to provide high quality groundwater samples. Very easy to operate 125 psi output Pre-set flow rates Saves up to 99 user-created flow rates Uses 4 AA alkaline batteries, that last for 40,000 drive/vent cycles (100… Continue Reading »
Throughout the two days of the symposium, attendees were provided with the opportunity to discuss environmental applications and monitoring methodologies with Solinst technical staff. The attendees were able to view hands-on demonstrations of Solinst instrumentation, including Solinst STS Telemetry Systems, Leveloggers®, Bladder Pumps, and Multilevel Groundwater Monitoring Systems. Solinst staff were there to answer any questions about the equipment… Continue Reading »
Jim Butler from the Kansas Geological Survey at the University of Kansas provided a great presentation to close the symposium. Jim discussed work being done by the Kansas Geological Survey at monitoring wells that have been set up to collect continuous records of water level and barometric pressure. Although not the initial focus of their studies, they… Continue Reading »
The symposium continued on Day Two with a presentation from the Ontario Ministry of the Environment. The presentation focused on the province-wide stream water and groundwater monitoring networks that are currently being overseen by the Ministry of the Environment in partnership with Conservation Authorities and participating municipalities. These networks monitor ambient (baseline) stream water quality conditions… Continue Reading »
Day Two began with a very interesting presentation by Ed Harvey with the University of Nebraska-Lincoln. Ed presented ongoing research from two of Nebraska’s most unique groundwater dependent ecosystems – Eastern Saline Wetlands and Sandhills Fens. Due to the unique composition of the groundwater that feeds these two ecosystems, the species found in these environments are not native… Continue Reading »
