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 a site assessment and what is the difference between a site assessment and a site investigation?
The first step of the site assessment process is known as a preliminary assessment (PA). This assessment gathers historical and other readily available information on site conditions and surroundings to evaluate whether the site poses a potential threat to human health and the environment and/or whether further investigation is needed…

Why hasn’t the Norwood Landfill Site been identified as a Superfund Site? Two nearby landfills, Folcroft and Clearview, which were established and in use at the same time as Norwood Landfill and Dump have both been designated as Superfund sites.
EPA is still conducting its investigation of the Norwood Landfill Site to determine if it should be placed on the National Priorities List (NPL), or Superfund List. Thus far, the data collected has not demonstrated that the site warrants placement on the NPL. Both the Folcroft and Clearview Landfills went…

Can air cleaning devices that use bipolar ionization, including portable air cleaners and in-duct air cleaners used in HVAC systems, protect me from COVID-19?
Bipolar ionization (also called needlepoint bipolar ionization) is a technology that can be used in HVAC systems or portable air cleaners to generate positively and negatively charged particles. Provided manufacturers have data to demonstrate efficacy, manufacturers of these types of devices may market this technology to help remove viruses, including…

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…

Will an air cleaner or air purifier help protect me and my family from COVID-19 in my home?
When used properly, air purifiers can help reduce airborne contaminants including viruses in a home or confined space. However, by itself, a portable air cleaner is not enough to protect people from COVID-19. When used along with other best practices recommended by the Centers for Disease Control and Prevention, operating…

Why did EPA wait so long to begin its investigation of the Norwood Landfill and Old Norwood Dump?
In the months leading up to the preliminary assessment, EPA gathered information on the property to determine whether a site investigation under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) was warranted. EPA determined to proceed with an investigation and EPA began procuring contractor services to conduct the preliminary…

How can I increase ventilation at home to help protect my family from COVID-19?
Ensuring proper ventilation with outside air is a standard best practice for improving indoor air quality. However, by itself, increasing ventilation is not enough to protect people from COVID-19. When used along with other best practices recommended by the Centers for Disease Control and Prevention, increasing ventilation can be part…

What is Upper-Room Ultraviolet Germicidal Irradiation (UVGI)? What is HVAC UVGI? Can either be used to disinfect the air and help protect myself from COVID?
A professionally designed system of ultraviolet germicidal irradiation (UVGI) that is well installed and maintained can effectively kill the virus that causes COVID-19 and help protect people from the disease indoors. Typically, UVGI systems are installed near a room ceiling (upper-room UVGI) or inside the HVAC system of a building…

What is the key question EPA tries to answer through a site investigation?
Findings of the site investigation determine what hazardous substances may be present, whether they may be released to the environment, and any potential threat to human health. Information about the site that is collected in the preliminary assessment and site investigation phase helps EPA to evaluate the risks posed by…
