on communities across the country. Exposure to certain toxins in the environment (such as chemicals in tobacco smoke, chemicals used in commerce or radiation) can cause cancer. EPA’s efforts to assess and reduce cancer risks are wide-ranging.

As part of this effort, the President convened his “Cancer Cabinet,” which includes the leaders of more than 15 agencies, offices and departments, including EPA Administrator Michael Regan. The Cancer Cabinet helps coordinate efforts across the federal government to advance the President’s vision for “ending cancer as we know it.” In June 2022, the Cancer Cabinet identified five priorities: <ol> <li>Close the screening gap.</li> <li>Understand and address environmental exposure.</li> <li>Decrease the impact of preventable cancers.</li> <li>Bring cutting edge research through the pipeline to patients and communities.</li> <li>Support patients and caregivers.</li> </ol> EPA’s mission is to protect public health and the environment. One way we do that is by reducing risks people face from toxic exposures. Certain chemicals and radioactive materials can cause cancer when people are exposed to them. EPA conducts research to understand where these risks come from, develops and implements regulations to reduce these risks, and supports voluntary efforts to reduce exposure to carcinogens. <div data-embed-button="paragraphs" data-entity-label="Paragraphs" data-paragraph-id="fd870437-90b2-4f84-bcfb-7edda5f75cf0" data-paragraph-revision-id="14808" data-langcode="en" data-view-mode="embed" data-entity-embed-display="entity_reference_revisions:entity_reference_revisions_entity_view" data-entity-type="embedded_paragraphs" data-entity-uuid="fd870437-90b2-4f84-bcfb-7edda5f75cf0" data-entity-embed-display-settings="[]" class="embedded-entity"> <div class="usa-summary-box" role="region" aria-labelledby="summary-box"> <div class="usa-summary-box__body"> <h2 class="usa-summary-box__heading" id="summary-box"> Reigniting the Cancer Moonshot </h2> <div class="usa-summary-box__text"> Learn more about the Cancer Moonshot’s mission to accelerate the rate of progress against cancer and the goal of reducing the cancer death rate by 50% over the next 25 years and improving the life experience of those living with and surviving cancer and their caregivers. <ul> <li><a href="https://www.whitehouse.gov/briefing-room/statements-releases/2022/02/02/fact-sheet-president-biden-reignites-cancer-moonshot-to-end-cancer-as-we-know-it/">Read the President Biden Reignites Cancer Moonshot to End Cancer as We Know It fact sheet</a>.</li> <li>Find more information about actions other federal partners are taking in <a href="https://www.whitehouse.gov/cancermoonshot/progress-updates/fact-sheets/">recent White House fact sheets announcing progress toward Biden's Cancer Cabinet goals</a>.</li> </ul> </div> </div> </div> </div> <hr> <h2 class="highlight"><a id="highlighted" name="highlighted"></a>Highlighted Programs and Efforts</h2> <h3><a id="toxics" name="toxics"></a>Addressing Pesticides and Toxic Chemicals</h3> The Office of Chemical Safety and Pollution Prevention (OCSPP) evaluates new and existing pesticides and toxic chemicals for risks to human health, including cancer, and — when needed — puts measures in place to protect against these risks.

Through water quality-based and technology-based programs under the CWA, EPA works with Tribal and state partners to reduce discharges of carcinogens to water bodies. Under the SDWA, EPA establishes National Primary Drinking Water Regulations to reduce exposure to likely carcinogens by setting enforceable standards as close as feasible to levels at which there is no cancer risk. EPA’s Office of Water also works closely with states, tribes and drinking water systems by providing technical assistance and funding that work towards providing safe and clean drinking water. <ul> <li><a href="/ground-water-and-drinking-water/national-primary-drinking-water-regulations">National Primary Drinking Water Regulations (NPDWR)</a> - NPDWRs are legally enforceable  standards expressed as Maximum Contaminant Levels (MCLs), or treatment techniques that apply to public water systems. NPDWRs include testing and operational requirements for water systems to protect public health by limiting the levels of contaminants in drinking water. EPA sets non-enforceable MCL goals at zero for carcinogens and enforceable MCLs for carcinogens as close to the MCL goal as is feasible taking cost into account, such as acrylamide, benzene, benzo(a)pyrene, carbon tetrachloride, epichlorohydrin, ethylene dibromide, hexachlorobenzene, pentachlorophenol, tetrachloroethylene, trichloroethylene (TCE), uranium, vinyl chloride, and others.</li> <li><a href="/sdwa/drinking-water-health-advisories-has">Safe Drinking Water Health Advisories</a> - Health advisory documents provide technical information on chemical and microbial contaminants, including known or suspected carcinogens, such as PFOA or PFOS, that are known or anticipated to occur in drinking water. EPA issues health advisories for contaminants that are not subject to an NPDWR. Health advisory values/levels identify the concentration of a contaminant in drinking water at which adverse health effects and/or aesthetic effects are not anticipated to occur over specific exposure durations (e.g., 1 day, 10 days, a lifetime). Health advisories provide information to drinking water systems and officials responsible for protecting public health when emergency spills or other contamination situations occur. They help tribes, states, and local governments inform the public and determine whether local actions are needed to address public health impacts.</li> <li>Clean Water Acter Technology-Based Programs - Many industrial facilities manufacture or use chemicals. EPA issues national regulatory standards for industrial wastewater which can contain carcinogens that will be discharged to water bodies (direct discharges) and to municipal sewage treatment plants (indirect discharges).

For two PFAS – perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) — EPA reviewed the weight of the evidence and determined that PFOA and PFOS are likely to be carcinogenic to humans. <a data-entity-substitution="canonical" data-entity-type="node" data-entity-uuid="2b0a30d3-b55d-477d-abf7-37587f33c211" href="/pfas">Find more information about PFAS</a> and learn how EPA developed the <a href="/pfas/pfas-strategic-roadmap-epas-commitments-action-2021-2024">PFAS Strategic Roadmap</a>. <ul> <li><a data-entity-substitution="canonical" data-entity-type="node" data-entity-uuid="fe60f5fc-faf6-4e5b-b33d-d1f77cf1b8d3" href="/sdwa/and-polyfluoroalkyl-substances-pfas">Final PFAS National Primary Drinking Water Regulation (NPDWR)</a> – In April 2024, EPA issued the first national, legally enforceable drinking water standard for six PFAS to protect communities.
