Environmental Health Resources for the COVID-19 Pandemic

Printer Friendly, PDF & Email

The transmission of SARS-CoV-2, the virus that causes COVID-19, occurs primarily via direct contact with or respiratory droplets from an infected person. However, there is evidence to suggest that transmission via other modes – such as contaminated surfaces, aerosols, or contact with fecal material – is possible. As such, environmental health practitioners have a key role to play in promoting general hygiene measures as well as addressing unique information needs as the pandemic affects all aspect of public and private life.

This topic page has been created to promote key COVID-19 resources to environmental health practitioners and related professions. We are actively collecting and curating resources from more than 50 Canadian and international public health agencies, and will be promoting those resources via social media and by providing the essential resources on this topic page. This information is current to the date at the bottom of the page.

Cleaning and Sanitation in Community Settings

  • Chlorine Dilution Calculator (BC FOODSAFE Program, 2020)
    This easy-to-use online calculator helps you determine how much liquid bleach to add to water to get your desired concentration (ppm) of chlorine solution. This tool was developed to assist Environmental Health Officers, food establishment operators, care facility operators, swimming pool operators, and the public to prepare the appropriate concentration of chlorine solution using bleach (sodium hypochlorite). Never mix bleach solutions with other cleaning products.

The study found that inactivation of coronaviruses in drinking water was greater at higher temperature. Inactivation in wastewater was dependent on the level of organic matter, and presence of antagonistic bacteria, however coronaviruses died off rapidly in wastewater. Spread of coronaviruses into the aqueous environment should be less than enteroviruses due to more rapid inactivation at ambient temperature.
