Other programs in Delaware are also making great strides in protecting our watersheds. Check out these resources to learn more


    • Delaware Environmental Observing System
    • DEMAC – Delaware Environmental Monitoring & Analysis Center
      There are several environmental monitoring initiatives currently ongoing in Delaware. DEMAC works with agencies and research groups throughout the State of Delaware to establish and maintain a coordinated approach to disseminating environmental data to governmental agencies, K-12, and the general public. Delaware environmental monitoring competencies currently include:

      • a network of high-frequency radar transmit-receive sites
      • the Delaware Environmental Observing System (DEOS)
      • a real-time satellite receiving station
      • diverse coastal and Delaware Bay observations
      • ground and surface water availability (DGS)
    • DNREC Environmental Navigator
    • DNREC Water Quality Monitoring Network Data Portal
    • FirstMap
    • Flooding and Dam Safety
    • Flora of Delaware Online Database – The tools on this site search for one or more plants found in Delaware. Search levels are intended to help you focus on the information most important to you. Dropdown lists allow “one-click” access to the plants database, while the text blocks, check boxes and radio buttons are used to narrow your search based on desired criteria.
    • USGS Current Water Data for the Nation
    • Vegetation Community Mapping Database – The Delaware Statewide Vegetation Community Mapping Project seeks to map all of the vegetation communities and land covers present in the state of Delaware. Delineations are drawn to the finest extent possible (no defined minimum mapping unit) using aerial imagery analysis, field observations, and data obtained from others.


  • Delaware Department of Natural Resources & Environmental Control (DNREC)
  • DNREC Site Investigation and Restoration Section (SIRS)
    SIRS is part of DNREC’s Division of Waste & Hazardous Substances. The mission of the SIRS is to identify sites with releases of hazardous substances, prioritize them for cleanup based on their potential risk to public health, safety and the environment, and to promote the reuse of contaminated properties. The Section manages hazardous substance release sites in Delaware in accordance with the Hazardous Substance Cleanup Act (HSCA). HSCA applies to all of the programs that are available through SIRS, including the Brownfields Program, Voluntary Cleanup Program, State led projects and Enforcement. In addition, the SIRS assists the EPA in management of sites in Delaware that are included on the Federal National Priorities List (NPL). Management of the contaminated sites within Delaware aids in the improvement of overall environmental health within Delaware’s watersheds. An important aspect of the SIRSs work on individual sites within the watersheds is the identification and remediation of contaminants that impact or have the potential to impact the State’s waterways.

    • A list of sites that are managed through the SIRS can be found here.
    • By clicking on an individual Program ID in the left column of the table, or by accessing choices under the “Navigation” heading on the left hand side of the webpage, detailed information about each site regulated by SIRS or other Division of Waste & Hazardous Substances Section/Branch can be obtained.

  • DNREC Division of Watershed Stewardship





  • University of Delaware Citizen Monitoring Program
    Since 1991, our dedicated corps of Citizen Monitoring volunteers have been taking water samples on a regular basis throughout Delaware’s coastal watershed to measure a broad range of important water quality characteristics. The data they gather provides scientists and resource managers with a clearer picture of the estuary’s health and the trend information needed to understand and manage the ecosystem. We invite you to explore our activities and learn more about what our volunteers are doing to help improve the health of Delaware’s water resource. Perhaps you, too, will want to take part in providing the timely and accurate data that complements the state’s other monitoring programs.
  • Nonpoint Education for Municipal Officials (NEMO) Program
    Delaware NEMO is an educational program for local decision makers that addresses the relationship between land use and natural resource protection, with a focus on watersheds. NEMO, the acronym for Nonpoint Education for Municipal Officials, derives its name for its emphasis on educating local decision makers — elected officials, town managers, and community members who serve on local planning commissions — about how the land use decisions they make affect water quality and other natural resources. Delaware NEMO ’s goal is to arm community leaders with the knowledge and understanding that will help them make better decisions about development while minimizing the impact on water quality and other natural resources. How you protect your natural resources will affect your community for generations.
  • University of Delaware Water Resources Center
  • Sustainable Coastal Communities Initiative
    The University of Delaware Sustainable Coastal Community (SCC) Initiative is an approach to address growth, land use, and environmental impacts in southern Delaware. The primary goal is to deliver science-based information to aid in decision making that aid in fostering:

    • Healthy coastal economies that include a diversity of economic possibilities, an abundance of recreation and tourism opportunities, and coastal access for all citizens;
    • Coastal communities that make efficient use of land, energy and water resources and protect the resources needed to sustain coastal ecosystems and quality of life;
    • Coastal citizens, community leaders, and industries that recognize the complex interrelationships between social, economic and environmental values in coastal areas and work together to balance multiple uses and optimize environmental sustainability.
