GLEC Team to Conduct 2018-2019 National Rivers and Streams Assessment

September 20, 2017

GLEC was awarded a competitive Task Order by the USEPA Office of Water to conduct field sampling for the 2018-2019 National Rivers and Streams Assessment (NRSA). The NRSA is a major element of four ongoing surveys under EPA’s multi-year National Aquatic Resource Surveys (NARS) program designed to assess the ecological health and condition of U.S. waters. The $5.4 million award follows GLEC’s field sampling, logistics, and training support for the NARS 2017 National Lakes Assessment. The GLEC NRSA 2018-2019 contracting team includes EnviroScience, Inc., the Amnis Opes Institute, and the Midwest Biodiversity Institute. Field crews from all four organizations plan to sample some 940 wadeable stream and larger river sites throughout the conterminous U.S. during the 2018 and 2019 survey seasons. Water, river beds and riparian habitats will be sampled and assessed for a variety of chemical and biological indicators, including nutrients, benthic macroinvertebrates, periphyton, chlorophyll, fish tissue, and fecal indicators.




GLEC operates one of only a few U.S. laboratories accredited for whole sediment toxicity testing. GLEC also maintains NELAP accreditation for chlorophyll and nutrient chemistry testing.


GLEC's Columbus, OH laboratory is ADEQ accredited for Acute Toxicity and Chronic Toxicity testing.
