NOTICE to KLWD ratepayers/water users. Boil Water Advisory.
The recent snow, rain and stormy weather has raised the turbidity levels in the lake and our water system to the point that we can not be sure how effective is the water treatment. As a result, we are acting on the cautionary side and issuing a Boil Water Advisory.
The Boil Water Notice will be lifted once we are assured the water is safe to drink. Frequent Water samples will be taken for testing until we are sure the water quality meets safety standards.
Turbidity is a laboratory measure of the relative clarity or cloudiness of water. It is an indirect measure of the suspended particles in the water and is a general measure of the scattering and absorbing effect that suspended particles have on light.
Turbidity–causing particles commonly arise from the weathering of rocks and soils during rainfall events or during rapid snow melt events, which are common during the fall and winter periods within Island Health. Turbidity–causing particles can also be present in the summer due to the growth of biological organisms such as algae, cyanobacteria or zooplankton.
The higher the turbidity level, the cloudier the water looks.
Turbidity is measured in nephelometric turbidity units (NTU). At 1.0 NTU the water is clear. The turbidity objective for drinking water from surface water supplies is less than 1.0 NTU. High turbidity can interfere with the disinfection of drinking water by causing our chlorination processes to become ineffective in destroying pathogens.
Tap water should be boiled for one minute. Use any clean pot or kettle. Kettles that have automatic shut offs are acceptable. After boiling, let the water cool by leaving it on the counter or in the refrigerator in covered containers. After water is boiled it can be stored in food grade containers at room temperature or in the refrigerator.
- Boiled water is required for Drinking purposes – This includes all beverage concentrates such as fruit juice and iced tea where water is added.
- Food preparation – This includes washing fruits and vegetables that will not be cooked. Water used as an ingredient does not need to be boiled prior to use, providing it will be brought to a boil during the cooking process.
- Coffee Machines – Coffee machines usually produce water heated to about70 to 80 degrees Celsius, which is sufficient to destroy pathogens. This temperature must be maintained for a sufficient amount of time to ensure that all harmful organisms are destroyed. Therefore, let the coffee stand for at least five minutes before drinking.
- Brushing teeth – This includes daily oral hygiene such as cleaning dentures
- Infant formulas – Formulas should always be prepared by using boiled tap water or bottled water that is boiled.
- Making Ice – It is important to note that freezing does not destroy most pathogens. Bacteria and viruses can survive in frozen products for long periods of time. Discard any ice made from contaminated or potentially contaminated water
- Fruit and vegetable washing – Boiled water should be used to wash all produce that is to be eaten raw.
- Home canning – To be safe postpone home canning until the boil water notice has been rescinded.
- Beer and wine making – To be safe postpone beer and wine making until the boil water notice has been rescinded.
- Water for pets – Veterinarians that were consulted by VIHA recommend that drinking water for pets including dogs, cats, birds and reptiles should also be boiled. Information on water quality for livestock can be accessed at the BC Ministry of Environment water quality objectives website .
- Immune-Compromised Individuals – People who are immune compromised should always boil their tap water for the purposes above.
