Reports & Testimonies

  • GAO’s recommendations database contains report recommendations that still need to be addressed.

    GAO’s recommendations help congressional and agency leaders prepare for appropriations and oversight activities, as well as help improve government operations. Recommendations remain open until they are designated as Closed-implemented or Closed-not implemented. You can explore open recommendations by searching or browsing.

    GAO's priority recommendations are those that we believe warrant priority attention. We sent letters to the heads of key departments and agencies, urging them to continue focusing on these issues. These recommendations are labeled as such. You can find priority recommendations by searching or browsing our open recommendations below, or through our mobile app.

    Recommendation: To increase EPA's consistency, transparency, and clarity in implementing the Safe Drinking Water Act in a way that better assures the public of safe drinking water, and to systematically implement the statutory requirement to consider for regulation the contaminants that present the greatest public health concern, the EPA Administrator should require that the Office of Water to develop a coordinated process for obtaining both the occurrence and health effects data that may be needed for the agency to make informed regulatory determinations on these priority contaminants.

    Agency: Environmental Protection Agency
    Status: Open

    Comments: In May 2017, while EPA cited the January 2016 document, "EPA's Protocol for the Regulatory Determinations 3," that includes clearer, more explicit description of the occurrence data EPA uses and the health assessment sources, it does not address the recommendation's intent that EPA develop a coordinated process for obtaining both the occurrence and health effects data that may be needed for the agency to make informed regulatory determinations on priority contaminants. Since most, if not all of the sources cited are data that EPA was using at the time the report was issued, GAO is keeping this recommendation open. As GAO reported, the approach EPA currently uses does not provide the agency with all of the data it needs in a timely manner to support determinations for some priority contaminants.
    Recommendation: In light of EPA's decisions to issue health advisories in conjunction with determinations to not regulate certain contaminants that have been detected in some public water systems at levels of public health concern, the EPA Administrator should (1) determine whether the Office of Water's use of health advisories provides sufficient information on these unregulated contaminants to support timely and effective actions by states, localities, public water systems, and the public to ensure the safety of public drinking water, and (2) if not, direct the Office of Water to develop a plan to more effectively communicate such information to these entities.

    Agency: Environmental Protection Agency
    Status: Open

    Comments: As of May 2017, EPA indicated that its Drinking Water Standards and Health Advisories tables provide a summary of previously published concentrations of drinking water contaminants that are protective of public health, and that the agency periodically updates these tables to summarize health advisories and regulations published to date. Since the table was last updated in 2012, and work is underway to revise it and make the information more accessible, GAO will monitor EPA's progress before closing this recommendation.
