Overview
Designed for field or lab use, the Geotech Geopump Peristaltic Pumps offer single-stage pressure or vacuum pumping of liquids to depths of 27 feet (at sea level). They are ideally suited for sample removal from shallow wells and surface water sources. They operate by mechanical peristalsis, so the sample only comes in contact with the tubing to ensure sample integrity, easy cleaning and replacement. With the optional stainless steel tubing weight, tubing can be lowered to a specific depth without curling or floating on the surface of the water.
Series I Geotech Geopump Peristaltic Pumps
Available in AC only, DC only, or an AC/DC combination. These units have one pumping station, which can be piggybacked for multi-station pumping. They have variable speeds ranging from 60 RPM to 350 RPM.
Series II Geotech Geopump Peristaltic Pumps
Available in AC only, DC only, or an AC/DC combination. They have two pumping stations, which can also be piggy-backed for multi-station pumping. The first pumping station has a variable speed of 30 to 300 RPM and the second station 60 to 600 RPM.

SUNY ESF/Syracuse U. study finds in-stream restoration structures effective
Planning stream restorations is becoming more important as the number of projects increases nationwide, in efforts to enhance water quality and habitat health of surrounding areas. 
 
Researchers at the State University of New York College of Environmental Science and Forestry (SUNY ESF) and Syracuse University led a study of two streams in upstate New York that had undergone restoration. They found restoration work created large areas of "transient storage" where water is temporarily retained behind restoration structures that enhanced downwelling to rates not observed in reference reaches. In natural streams, these transient storage zones are known to host biological and chemical processes that allow the stream to clean itself.

Sediment in Washington State’s Puget Sound is growing more polluted, and scientists aren’t entirely sure why. Water quality specialists from the U.S. Geological Survey aim to change that. 
 The Washington State Department of Ecology recently reported that some aspects sediment health in the sound have gotten worse over the last decade. Poor sediment quality has adversely impacted macroinvertebrates and water quality. A new USGS study is tracing Puget Sound sediment upstream to its tributary rivers to evaluate sediment volumes and quality.

A nutrient monitoring effort throughout a degraded Chesapeake Bay watershed is helping chart the path of nitrate through the system. The monitoring is part of a plan to target federally funded agricultural conservation practices to the places in the watershed that need them most. 
 
The Choptank River is among one of the largest tributaries to the Chesapeake Bay, a system plagued by excess nutrients. The Choptank flows across the Delmarva Peninsula, a 170-mile-long piece of land that makes up the bay's eastern shore. 
 
More than half of the Choptank's watershed is covered in agricultural land, which is part of the reason the river has been listed as impaired under Clean Water Act standards for nutrients and sediment.
