  • 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 Continues Support for USEPA Drinking Water Monitoring Program
    September 11, 2017

    The 1996 Amendments to the Safe Drinking Water Act established an unregulated contaminant monitoring program by which public water systems (PWSs) monitor, on a five-year cycle, for up to 30 contaminants considered to be potential drinking water contaminants. The U.S. Environmental Protection Agency, Office of Water, Office of Groundwater and Drinking Water is responsible for implementing this program under the applicable Unregulated Contaminant Monitoring Rule (UCMR). UCMR program outcomes benefit public health by providing EPA with scientifically valid data on the national occurrence of selected contaminants in drinking water for use in regulatory action. In August 2017, GLEC was awarded a six year $11.4 million contract to provide UCMR technical support. Support includes: designing and implementing the monitoring program; coordinating with states/tribes/territories and individual PWSs; designing sampling logistics; assembly and distribution of sampling equipment; tracking sampling and analysis completeness; outreach and education; laboratory oversight and data quality review; evaluation of results; and compliance assistance to water system operators. This is the fourth UCMR support contract awarded to GLEC since 2000.

  • Michigan Part 201 Sediment Quality Assessments

    The Michigan Department of Environmental Quality (MDEQ) considers contaminated groundwater venting to surface water a significant threat to the State’s surface water quality. During 1995, and more recently, during 2002, the MDEQ promulgated rules under Part 201 of the Natural Resources and Environmental Protection Act, (NREPA; of 1994, as amended) to regulate the discharge of contaminated groundwater to surface waters of the State. Part 201 requires that if a remedial action proposes to allow groundwater to vent to surface water from a facility above generic groundwater/surface water interface (GSI) criteria, then the discharge must comply with the requirements of Part 31 of the NREPA.
