The Solinst Model 615 Drive-Point Piezometer has a stainless steel, 50 mesh cylindrical filter-screen, within a 3/4" (20 mm) stainless steel drive-point body, screen support and a barbed fitting for attachment of sample tubing. Optional heavy-duty extension couplings are also available to create a strengthened and more rugged piezometer.
The inner barbed fitting allows connection of 5/8" OD x 1/2" ID (16 mm x 12 mm) LDPE or Teflon sample tubing. This prevents sample water from contacting the steel extension rods, and maintains high sample integrity, even when inexpensive carbon steel extensions are used.
The tubing barb connects 5/8" OD x 1/2" ID (16 mm x 12 mm) LDPE or Teflon sample tubing to the piezometer. This barbed fitting prevents sample water from coming in contact with the extension rods in order to maintain sample integrity. Piezometers without a tubing barb such as the 615N and 615NS are designed for use with water level meters.
All Solinst 615 Drive-point Piezometers are 3/4" in diameter with a 1" diameter tip. The shielded version includes an replaceable 1.5" diameter shield.
While the 615 Drive-Point Piezometers are commonly installed as permanent well points, they are reusable. However, if a shielded version (615S or 615SN) is used, the shield portion is single-use only and replacements are available.
Piezometers are not suitable for all soil types, so the depth limitation will vary. The maximum depth penetration of the 615 piezometer will depend on the soil conditions, shield use and drive method used (slide hammer or drill). The piezometer itself is 6 inches long.

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.

Charles River Algal Blooms Stop Swimming and Launch a Floating Wetland
The Charles River used to be a swimming hotspot for Cambridge and Boston residents. Decades of industrial pollution and nutrient runoff have degraded water quality and eliminated public swimming in the Lower Charles, but a movement is afoot to get Boston and Cambridge back in the water. One step toward the goal of a safely swimmable river—without the need to obtain a permit, as is now necessary—is detecting and managing the harmful algal blooms that appear on the river. An experimental floating wetland and new research and analysis of water quality data that shows a possible effective detection system for algal blooms on the Charles River are two new steps toward the goal of safe, accessible swimming.

Harnessing the Gulf Stream for Renewable Energy
The Gulf Stream, the massive western boundary current off the east coast of North America, moves water from the Gulf of Mexico north and west across the Atlantic Ocean. There’s a lot of energy in that much moving water and researchers are trying to put it to use. Although the Gulf Stream’s path shifts (researchers say it acts like a wiggling garden hose), in a couple of spots, it stays relatively stable. At one such spot off the coast of Cape Hatteras, North Carolina, researchers have dropped moorings and research instruments to study the current with the eventual goal of harnessing it for renewable energy.
