Solinst Video: How the Discrete Interval Sampler Obtains No-Purge Samples
Solinst has posted a video showing how the Model 425 Discrete Interval Sampler obtains a representative groundwater sample. The video walks you through all the steps, from determining your sampling depth and setting up the equipment, to operation and groundwater sample collection.
A Discrete Interval Sampler obtains samples without the need for purging. It is pressurized to ensure no water enters during deployment and retrieval. The sampler is de-pressurized at a discrete depth to collect a sample. These operating principles are clearly shown in the video.

New Artesian Well Fitting for Monitoring with Leveloggers
An artesian well can be defined as one that taps into a confined aquifer that is under positive pressure, and therefore, water in the well rises above the top of the aquifer.
When monitoring continuous artesian conditions, the well is sealed by a wellhead. Solinst has released a new Artesian Well Fitting that can be used with the sealed wellhead to allow measurement of the piezometric surface using a Levelogger.
The Artesian Well Fitting is designed for use with a Levelogger deployed on a Direct Read Cable. Please refer the Assembly Instructions for more details.
For a general overview of using Leveloggers in artesian wells, please see the Artesian Monitoring section in the Levelogger User Guide.

Solinst Telemetry Monitors North Carolina Aquifers
More than half of North Carolina's population gets its drinking water from aquifers. With a large amount of the state's groundwater also being used for irrigation, agricultural, industrial and commercial uses, it is imperative for the state to properly manage its aquifers. As such, the Groundwater Management Branch oversees a statewide network of over 630 monitoring wells, many equipped with automatic water level recorders.
To find out how Solinst STS Telemetry is being used in this network, read the full story here: www.solinst.com/onthelevel-news/2015/10/solinst-telemetry-helps-assess-drought-conditions-in-north-carolina/

19 CMT Systems Successfully Installed in Challenging Geology
19 CMT Multilevel Systems were installed to characterize and track a contaminant plume below a manufacturing facility in Wales, UK. RS Hydro, Solinst equipment representative for the UK, provided training to the drilling company contracted to complete the installations. The 19 CMT Systems were installed within just two weeks. This was impressive, given that all of the wells were drilled through the building's foundation, and challenging sticky clay-like geology was encountered.

Blog Post: Levelogger Edge Used in Antarctic Tidal Study
A Levelogger Edge water level datalogger was used to monitor tidal fluctuations in the Davis Sea, Antarctica from April 2013 to December 2013. A custom-built "monitoring shaft" was used to protect the Levelogger in the harsh conditions.
The Levelogger was set to record hourly readings, and then compensated using barometric data from a nearby weather station. The data was then compared with a separate tidal gauge that was recording simultaneously.
To find out how the Levelogger performed, read the post in the Solinst ON THE LEVEL blog: www.solinst.com/onthelevel-news/2015/01/levelogger-edge-data-verified-harsh-conditions-antarctic-tidal-study/
