Effects of Soil Health Best Management Practices on Water‐Quality and Soil-Moisture in Soldier Creek, Nemaha County Kansas

In October 2020, The U.S. Geological Survey, in cooperation with the Kansas Department of Health and Environment (KDHE), began long‐term in‐stream monitoring downstream from the headwaters of Soldier Creek, a KDHE identified basin with a high probability of large‐scale implementation (more than 50% of area) of soil health best management practices (BPMs) to quantify potential changes in streamflow...

Surface Water and Groundwater Availability and Quality in the Prairie Band Potawatomi Nation Reservation

The Prairie Band Potawatomi Nation (PBPN) in Jackson County, Kansas lies within the Big Soldier and Little Soldier Creek basins. The PBPN needs surface and groundwater quality and quantity data for water management purposes and for developing and implementing a water quality program to protect the water of the reservation for the benefit of current and future generations. In January 2020, The U.S...

Analytical Capabilities, Sample Requirements, and Instrumentation

OGRL works independently or collaboratively to pair fate and transport with biological experiments and effects. OGRL has three main focuses: 1. Development and modification of robust analytical methods needed for analysis of compounds in multiple matrices to address relevant environmental health issues. 2. Conduct independent and collaborative lab to national based studies to provide new knowledge...

OGRL Algal Toxins Methods of Analysis

Algal toxins are a group of toxic compounds produced by a range of photosynthetic freshwater and marine plankton. These toxins have the ability to cause sickness in animals and humans and in severe cases lead to death. OGRL has the ability to evaluate and conduct occurrence, fate, transport, effects, and treatability studies methods.

Measuring POEA, a Surfactant Mixture in Herbicide Formulations

POEA (polyoxyethylene tallow amine) is a surfactant with known toxic effects on aquatic organisms. POEA was added to the original formulation of the herbicide glyphosate to aid in its application and effectiveness at controlling weeds. U.S. Geological Survey (USGS) scientists developing methods to measure POEA in the environment have shown that it’s a complex and variable mixture of related...
