Overview
The Solinst Model 800 Low Pressure Packers inflate with a hand pump and are available in 1.8" and 3.9" (46 mm and 99 mm) 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.
Design
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. The inflation line is standard LDPE tubing and connects to the packers using a simple push fitting.
Applications
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. If a rigid drop tube is not required for the application, it is recommended that a safety line be attached 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.
Use
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.

Characterized by long-term accumulation under waterlogged conditions, peatlands exist on every continent and account for 3-4% of the global land surface . Small but mighty, these often overlooked wetland environments are estimated to hold as much as one-third of the world's organic carbon in their soil—twice the amount found in the entirety of the Earth's forest biomass. While healthy peatlands can trap and store carbon, regulate water, and provide important habitats for rare species, human alteration has disturbed peatland carbon and nitrogen cycles on a global scale. Approximately 12% of the world’s peatlands have been drained and degraded through conversion for agriculture, forestry, infrastructure development, and other uses.

Until recently, Sargassum –a free-floating seaweed–was distributed throughout the Sargasso Sea , the north Caribbean Sea, and the Gulf of Mexico. But in the space of a decade, this seaweed has, as one scientist remarks , “Gone from a nonfactor to the source of a terrible crisis.” Driven by climate change, anomalous North Atlantic Oscillation in 2009-2010 and a glut of anthropogenic pollutants, sargassum has proliferated. Seasonally recurrent mats as deep as 7m now bloom in the “Great Atlantic Sargassum Belt” (GASB), which covers areas of the Atlantic from West Africa to the Caribbean Sea and Gulf of Mexico. Every year, millions of tons wash up along the shores of more than 30 countries . Dr.
