Flood Information from AHS

Flood Information from AHS – County of GP

Below is a list of documents provided by Alberta Health Services to provide information to resident’s who have been affected by the recent flooding.

Cistern Cleaning & Disinfection
Water in a cistern may not necessarily be clean and potable. Hauled water may already be contaminated and even if the water has been treated, it can deteriorate during storage. Over time, the loss of chlorine residual can lead to microbial re-growth; sediments/sludge can accumulate in the cistern or animals or insects can fall in.

Cleaning the House After a Flood
Because floodwaters carry disease germs from raw sewage, the only safe flood-exposed foods are those sealed in metal cans. These may be safe to use if the seal is undamaged and the outside of the container is properly cleaned and sanitized. Damaged or blown (bulged) cans should be discarded.

Disinfecting Private Water Supplies After Flooding
Avoid drinking untreated well water that have become flooded, or if contamination is suspected. Private wells that have been affected by flooding or heavy rains must be disinfected and tested after flood waters recede before they are considered safe for using.

Flood Water Precautions
Flood waters may contain a number of risks that may affect your health. Some concerns with flood water include:

Shock Chlorination for Contaminated Wells
This shock chlorination procedure is designed for disinfecting groundwater wells that have been tested positive for E. coli or fecal coliform. For disinfecting wells to control iron or sulfur bacteria, please contact your Environmental Health Officer or Public Health Inspector.

Use Precautions When Cleaning Flooded Homes
Recent heavy rains in central Alberta have resulted in basement flooding, prompting Alberta Health Services to advise residents of proper techniques for flood cleanup.
