Take precautions with water during overland flooding

July 2, 2020

LETHBRIDGE – Overland flooding from heavy rains is occurring in many areas of southern Alberta, putting private water supplies at risk for contamination and presenting other potential hazards.

Standing or fast-moving flood water can contain a number of risks that might affect your health. Some concerns with flood water include the presence of raw sewage; chemical contaminants; debris; openings in the ground that are not visible; and other unseen hazards.

Remember the following when dealing with flooding in your community:

  • Do not attempt to enter fast-moving water or storm water overflow ponds. There is a severe life and safety issue with entering such water. Flood water should not be used for recreational purposes.
  • Do not drink or use any water well or cistern that has been contaminated with flood water. Your drinking water sources might need to be filtered and tested before consumption can resume.
  • Be aware that surface bodies of water (irrigation canals, dugouts and ponds) may have become contaminated with flood water. Always use precautions when using these water sources for drinking, cooking, bathing or recreational purposes.
  • Do not drink or come into contact with flood water. Many disease-causing organisms, such as E. coli, might be present.
  • Wash your hands with soap and a clean source of warm water after contact with flood water or handling items that have come into contact with flood water.
  • If you become ill with vomiting or diarrhea after contact with flood water, contact Health Link 811 or your family doctor.
