• The virus is susceptible to disinfectants used in water treatment.
  • Coronaviruses are NOT more resistant to disinfection than E. coli, which water systems must protect against.
  • Chlorination can be effective in destroying the virus.
  • A free chlorine residual, which must be maintained for public water systems to protect against microbes, is a good indicator that the water is safe from viruses. MVWA continually monitors the chlorine residual throughout the distribution system network.
  • Dilute bleach solutions (0.1% - 0.5%) and 70% alcohol have proven to be effective against similar coronaviruses.
  • Good hygienic practices are effective in controlling the spread of viruses.
