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.

Sewage an Unseen and Ignored Threat to Coral Reefs and Human Health
It’s an open, dirty secret that the ocean is used as the ultimate sewage solution. Each year trillions of gallons of untreated waste are sent to the ocean due to a widespread lack of sanitation technology or infrastructure that needs updating as cities and populations grow. As the impact of untreated sewage on the ocean becomes clearer, attention to the problem and strategies for dealing with it have not kept up. “This is a massive problem and it’s been largely ignored,” said Stephanie Wear, senior scientist and strategy advisor for The Nature Conservancy. Wear has turned her attention to raising the alarm about the effects of sewage on coral reefs, which often loses airtime to other pressing issues like climate change and overfishing.

Lake Superior Algal Blooms Surprise, Highlight Need for More Monitoring
In 2012, for maybe the first time, Lake Superior got scummy. Visitors to the Apostle Islands National Lakeshore reported algae washing up on shore around the park. It was a marked shift for the park, made up of a portion of the Lake Superior lakeshore and nearby islands. The water surrounding the park is cold, clear and typically low in nutrients: a combination unlikely to result in algal blooms. But, in 2012 and again in 2018 after violent storms, major algal blooms—ones observed over multiple days—washed ashore and clogged the beaches with unsightly, scummy algae. Not the usual suspects The algal blooms of Lake Superior are not the algal blooms of warmer, more nutrient-rich lakes like Lake Erie.
