Low Pressure Pneumatic Packers
These simple inexpensive packers inflate with a hand pump and are available in 1.8" and 3.9" (46 mm and 99 mm) diameters. Primarily for short term use in 2" and 4" (51 mm and 102 mm) monitoring wells, they can also be used in smooth boreholes and wells with 1.9 – 5" (48 – 127 mm) inside diameters. Typical inflation pressures for the 1.8" (46 mm) packers are from 20 – 40 psi (140 – 275 kPa) above hydrostatic pressure, and from 20 – 30 psi (140 – 205 kPa) for the 3.9" (99 mm) packers.
The Packers utilize a gland of black carbon reinforced rubber (BCR) on a Sch 80 PVC body. They are lowered on a support cable or a rigid PVC drop pipe. If a rigid drop tube is not required for your application, it is recommended to attach a safety line to the eyebolt provided. The Solinst Model 103 Tag Line provides a convenient, graduated support cable that can be used for this purpose, as well as for measuring placement depth. The inflation line is standard LDPE tubing and connects to the packers using a simple push fitting.
Single or Straddle Packers
Solinst packers are ideal for use with Solinst Bladder Pumps or Double Valve Pumps, which can be easily attached above the packers. The water inlet can be below a single packer, or through perforated pipe fitted between straddle packers. For hydraulic conductivity testing, Solinst Leveloggers can also be suspended, either below or between packers, from the eyebolt on the bottom of the packer.

New map shows significant groundwater depletion in Central California
Groundwater level data collected by a Central California county shows significant drops during the past 12 years, according to a San Luis Obispo Tribune article. 
 Data shows that groundwater has dropped by a minimum of 70 feet from 1997 to 2009 in the Paso Robles area of Central California. 
 In the past four years the areas of most significant decline have expanded north and south. 
 Drought and agricultural withdrawals are the likely culprits for the groundwater decline. 
Some advocates are calling for more responsible water use by vineyards in the area, while farmers note that the recent drought did not help the situation.
Read MoreCollecting Data at the Top of the World: How Scientists Retrieve Glacial Ice Cores
A helicopter touches down in the small town of Sicuani, Peru, at an elevation of 11,644 feet. Earlier that day, a boxcar brought fuel, drills, food, and other equipment for a glacial expedition. The year is 1979, and glaciologist Lonnie Thompson is preparing to lead a team to the Quelccaya ice cap in hopes of becoming the first scientists to drill an ice core sample from this glacier. 
 
 The only problem? The glacier is located at 19,000 feet in one of the most remote areas of the world. The helicopter takes off from the town, but the thin atmosphere at that elevation does not allow it to safely touch down on the ice– due to the aircraft’s weight, and it becomes unstable when the air is less dense.

In the Spring 2024 edition of the Environmental Monitor, we showcase researchers from across the world and the importance of monitoring natural disasters and the various symptoms of climate emergencies. Tracking the impacts of wildfires in Canada to air pollution in New York , this latest edition showcases how the influence of climate change and natural disasters transfers across state and country lines. Researchers spent the year gathering data, predicting disasters, and monitoring as a means of managing and understanding natural disasters. 
 
Our writers sought out environmental professionals dedicated to protecting human health , minimizing the impacts of natural disasters and creating monitoring systems.
