PFAS in Delaware

DNREC and the DHSS Division of Public Health are working with federal agencies to protect the environment and public health in Delaware from the effects of a group of synthetic chemicals known as PFAS.
The department has released findings from a comprehensive study of PFAS in surface waters across


PFAS and Wastewater

Nationwide studies since the early 2000s indicate that PFAS exist in influent, effluent and residuals (biosolids) of wastewater treatment plants (Bogdan, D. 2021). Some of the most frequently detected PFAS compounds are PFAAs (perfluoroalkyl acids). This makes wastewater treatment plants important in managing and mitigating the environmental spread of PFAAs and a key participant in protecting both


PFAS and Surface Water

PFAS and other toxic contaminants can enter surface water through overland flow, such as stormwater runoff, through industrial discharges, through atmospheric deposition and through discharge of contaminated groundwater.

    PFAS and Drinking Water

    The federal Safe Drinking Water Act governs the quality and testing of all public drinking water supplied by water systems in the United States. The EPA works with states, localities and water suppliers to implement drinking water regulations.

    Inside the DNREC Environmental Laboratory Responsible for Testing for Forever Chemicals and Other Contaminants

    When the Delaware Department of Natural Resources and Environmental Control needs to test water samples for contaminants, it turns to its Environmental Laboratory, which has been helping protect the state’s natural resources for 75 years — and will, before long, move into a new home. In this piece, Outdoor Delaware takes you into the lab to elucidate its important duties.


    East Basin Road Groundwater Site

    The U.S. Environmental Protection Agency (EPA) has added the East Basin Road Groundwater Site in New Castle County to the Superfund National Priorities List (NPL). The site is an approximately seven-square mile area surrounding the city of New Castle’s public wells.

    PFAS – Fighting Forever Chemicals in Delaware

    By Todd Keyser Beginning in the 1970s, firefighters used a special foam to put out jet fuel fires at Dover Air Force Base (DAFB). That foam figured prominently in 2006, when a C-5 cargo plane crashed just short of a runway after developing problems during takeoff. Fortunately, all 17 onboard survived the crash. But


    PFAS Investigation Sites

    This page contains a list of sites being investigated by DNREC for per- and polyfluoroalkyl substances (PFAS) in drinking water, groundwater or surface water in Delaware.

    Exposure Assessment Near New Castle Air National Guard Base

    In 2019, the Centers for Disease Control and Prevention (CDC) and the Agency for Toxic Substances and Disease Registry (ATSDR) initiated an exposure assessment for perf- and polyfluoroalkyl substances (PFAS) in the community near the New Castle Air National Guard Base in New Castle County.

    PCB Mass Loading Studies

    The DNREC Division of Waste and Hazardous Substances and Division of Watershed Stewardship are working together to study polychlorinated biphenyls (PCBs) and how they enter surface waters from hazardous substance release sites around the state.

    A Watershed Approach

    The Watershed Approach to Toxics Assessment and Restoration (WATAR) is a watershed-scale approach to evaluating where contamination comes from, how it gets into Delaware’s waterways and water bodies, and what effects it has on watershed health.

    Blades Groundwater Site

    On Sept. 1, 2020, the U.S. Environmental Protection Agency (EPA) announced the addition of the Blades Groundwater Site to the Superfund National Priorities List (NPL). The NPL is EPA’s list of priority sites with releases of hazardous substances, pollutants or contaminants requiring evaluation for possible remediation. The public announcement of the listing appears in the
