  • Invasive Blue Catfish in Chesapeake Bay Raise Concerns Over PFAS Contamination

    Invasive Blue Catfish in Chesapeake Bay Raise Concerns Over PFAS Contamination
    Jul 24 2024
    Blue catfish (Ictalurus furcatus), an invasive species in the Chesapeake Bay watershed, have become a focus for scientists and fisheries managers due to their rising numbers and potential ecological impacts. To address environmental concerns, the United States Geological Survey (USGS) and the Maryland Department of Natural Resources have collaborated to sample these catfish for per- and polyfluoroalkyl substances, commonly known as PFAS.

    PFAS are a group of human-made chemicals used in a variety of industrial and consumer products, including non-stick cookware, water-repellent fabrics, and firefighting foams. Known for their resistance to degradation, PFAS are often termed "forever chemicals" because they persist in the environment and can accumulate in living organisms over time. Elevated levels of PFAS in wildlife can pose significant health risks to both the animals and to humans who consume them.

    The blue catfish, originally introduced into the Chesapeake Bay for sport fishing, have proven to be highly adaptable and prolific. As an apex predator in non-native waters, these catfish prey on a wide variety of native species, including crabs, other fish, and mussels, disrupting local ecosystems. Consequently, understanding the contamination levels of PFAS in blue catfish is essential for managing their population and protecting the integrity of the Chesapeake Bay watershed.

    By systematically sampling blue catfish and measuring PFAS concentrations, USGS and the Maryland Department of Natural Resources aim to gather crucial data on the prevalence and distribution of these harmful chemicals. This information will not only help in developing effective management strategies for the invasive species but also in assessing the broader environmental and public health implications associated with PFAS contamination in the region.

  • Reviving Arid Streambeds: USGS Showcases Nature-Based Solutions for Thriving Ecosystems

    Reviving Arid Streambeds: USGS Showcases Nature-Based Solutions for Thriving Ecosystems
    Jul 23 2024
    Transforming a dry streambed into a thriving oasis is no small feat, but the U.S. Geological Survey (USGS) is proving that nature-based solutions can achieve remarkable results. These simple, yet effective, methods not only revitalize ecosystems but also bring substantial benefits to local communities and the environment.

    In a recent USGS project, an arid streambed previously marked by dust and aridity was transformed into a vibrant habitat teeming with life. This transformation was achieved by leveraging nature-based solutions, which often mimic or utilize natural processes to address environmental challenges.

    One of the key strategies employed by the USGS is the use of vegetative buffers and constructed wetlands. These features help to filter pollutants, prevent erosion, and enhance water retention in the landscape. By introducing native plant species, the project also promoted biodiversity, offering new habitats for a variety of wildlife.

    In addition to ecological benefits, these solutions provided significant advantages for the surrounding communities. Improved water quality and reduced flood risk are direct outcomes of better-managed landscapes. Furthermore, the restored streambed has become a local attraction, drawing visitors and promoting environmental education.

    The success of this project underscores the potential of nature-based solutions to address a wide range of environmental issues efficiently and sustainably. By studying and implementing these methods, USGS is paving the way for healthier ecosystems and more resilient communities.
