  • Will an Ozone Generator protect me and my family from COVID-19?

    No, do not use ozone generators in occupied spaces. When used at concentrations that do not exceed public health standards, ozone applied to indoor air does not effectively remove viruses, bacteria, mold, or other biological pollutants. Visit the Centers for Disease Control and Prevention's website for best practices to protect…

  • What is the status of the sampling data from Leslie Run and Sulphur Run?

    Sediment sampling in Leslie and Sulphur Run is complete. The data generated by this work are being evaluated and compared to human health and ecological risk threshold criteria. That will lead to a determination about whether additional actions will be required and what those actions should be.

  • Will running an evaporative cooler (sometimes known as a "swamp cooler") or whole-house fan help protect me and my family from COVID-19?

    Both evaporative coolers (or "swamp coolers") and whole-house fans can help protect people indoors from airborne transmission of COVID-19 because they increase ventilation with outside air to cool indoor spaces. Evaporative coolers are used in dry climates. They use water to provide cooling and increase relative humidity indoors. When operating…

  • Where can professionals who manage school, office, and commercial buildings get information on ventilation and filtration to respond to COVID-19?

    Professionals who operate school, office, and commercial buildings should consult the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) guidance for information on ventilation and filtration to help reduce risks from the virus that causes COVID-19. In general, increasing ventilation and filtration is usually appropriate; however, due to the…
