Overview
The YSI 1006 nitrate ISE sensor consists of a silver/silver chloride wire electrode in a custom filling solution. The internal solution is separated from the sample medium by a polymer membrane, which selectively interacts with nitrate ions.
Mechanics
When the probe is immersed in water, a potential is established across the membrane that depends on the relative amounts of nitrate in the sample and the internal filling solution. This potential is read relative to the Ag/AgCl reference electrode of the instrument pH probe. As for all ISEs, the linear relationship between the logarithm of the nitrate activity (or concentration in dilute solution) and the observed voltage, as predicted by the Nernst equation, is the basis for the determination.

Kansas State classes get a lesson in environmental remediation
Kansas State University professors transformed a plot of land from a problem to a classroom, teaching students on the fly to remediate nutrient pollution. 
 Saugata Datta, an associate professor of geology, and Nathan Nelson, an associate professor of agronomy, taught students to evaluate, sample and remediate land using Kansas Department of Health and Environment protocols. 
 It started when Chris Steincamp, an environmental lawyer and KSU alumnus, asked Datta if his geology students could restore a tract of land in Sylvan Grove Kan. 
 Datta jumped at the opportunity to give his students hands-on experience in a process usually reserved for regulators and consultants. 
 It helped that O.C.

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.

The largest dam removal in U.S. history, the deconstruction of the Klamath Dam is slated to begin this summer. The project includes four dams along the Klamath River with the first and smallest dam, Copco #2, scheduled for removal first. As each of the dams are torn down, scientists and consultants will keep a close eye on the state of the Klamath River downstream to assess the impact of undamming the river. 
 
Shawn Hinz, managing partner and environmental toxicologist with Gravity Consulting , has been involved with the Klamath Dam project for over a decade. Hinz was a part of these earlier steps, representing the academic stakeholder position as a graduate student sitting on a board of other stakeholders.
