How to Remove Viruses from Drinking Water
Some water-borne viruses can spread though water, including meningitis, gastroenteritis, conjunctivitis, SARs, hepatitis A, hepatitis E, and Typhoid can spread through water. There is no indication that Covid-19 spreads through water.
Waterborne viruses and bacteria cause hundreds of millions of people to become afflicted with sickness each year, simply because they ingested contaminated water.
How to Get Viruses Out of Water
If you are searching for a way to ensure your drinking water is safe from viruses, bacteria, and other pathogens, here are few options:
|1) Boil your water to remove viruses. Bring water to a rolling boil for at least one minute to kill viruses in water. This is a very effective way to ensure your drinking water is safe.|
2) Disinfect with chlorine or iodine. Today chlorine disinfection is used by most municipal water suppliers. But those on private well water should test their well water regularly for viruses and bacteria. To remove bacteria and viruses from your well, you can disinfect with a high dose of chlorine (known as "well shocking"). The amount of chlorine you use will depend on the presence of biofilm, the depth of your well, the water pH, water temperature, etc. You'll also need to determine the correct chemical concentration needed and exercise extreme caution as the chemicals are toxic.
Continue to test your well water as the quality of your water changes throughout the year.
|3) Install a UV Light Water Disinfection System. UV water disinfection is a chemical-free, economical way to destroy 99.99% of viruses (and 99.9999% of harmful bacteria and cysts). A UV light sterilizer can ensure water at every faucet in the household is free of viruses and bacteria 24/7.|
The Centers for Disease Control and Prevention (CDC) site states: "Ultraviolet Light (UV Light) can be used as a pathogen reduction method against some microorganisms. The technology requires effective pre-filtering due to its dependence on low water turbidity (cloudiness), the correct power delivery, and correct contact times to achieve maximum pathogen reduction. Manufacturer’s instructions must be followed."
Also, more and more households on city/municipal water are choosing to install a UV water filter system as an added layer of protection, because the public water system is often vulnerable to impurities leaching in. UV disinfection is considered to be a safe, effective way to disinfect water.
NOTE: The UV system's effectiveness is dependent on correct system sizing and low sediment and turbidity/cloudiness in the water. A prefilter before a UV system, such as included in the combo VIQUA IHS22-D4 UV system, can help remove sediment and cloudiness so that UV light can effectively inactivate viruses.
Remove Viruses from Water During an Emergency
The US Government recommends that to prepare for a pandemic, storm or other natural disaster, households should store a 2-week supply of water and food. And the need for making water safe from bacteria and viruses is more common than you might realize. Every day, hundreds of boil water notices are issued in cities throughout the U.S. With an installed UV water filter system, there is no need to boil water or any of the methods listed below.
1) Boil Water: While boiling water for one minute is one of the surest ways to kill viruses in drinking water, it is often not possible during an emergency because an energy source is needed to heat the water.
2) Household Bleach: You can also use unscented household bleach to disinfect water during an emergency, applying two drops of bleach per quart of water.
3) Gravity Water Filter: Typical water filters do NOT remove viruses and bacteria. But systems such as the Outback Emergency Water Filtration system have the right filters to protect against 99.99% of all viruses and 99.9999% of bacteria. The system has been used worldwide since 2003 by relief organizations such as the Red Cross and Peace Corps.
