What is a Boil Water Alert?
A Boil Water Alert is issued when disease-causing pathogens are detected, in order to protect you from water that is or will become unsafe to consume. There are more than 151,000 public water systems in the USA , and at any moment a handful of them can be under advisory. EPA regulations are responsible for the safety of your water. They ensure that municipalities conduct regular testing, proper maintenance, appropriate filtration, and disinfection of water before it’s piped out to your faucet.
Give yourself peace of mind by adding an ultraviolet disinfection system from Atlantic Ultraviolet Corporation® to your home or business. Also known as UV-C water purifiers, these systems are engineered to reduce risks associated with water contamination. UV-C is a rapid, safe, and chemical-free disinfection method that can eliminate much of the hassle involved when a Boil Water Advisories are issued.
Boil Water Alerts are much more common than you probably realize. In fact, much of the country faces multiple Boil Water Alerts throughout the year, meaning their water could become unsafe to consume at any moment.
From 2012 to 2014, there were 20,978 Boil Water Advisories gathered from the 50 U.S. states.— Water Quality Research Foundation, “Boil Water Notices”
Situations that Cause Contamination and Trigger Boil Water Advisories
Aging Infrastructure is a common cause of Boil Water Advisories. Most of the country’s pipes and water systems were designed and installed over 100 years ago. Time and environmental changes allow dirt and gravel around the pipes to settle, causing them to develop small fissures and cracks. Shifting pipes then lead to water main bursts, pipe corrosion, and fitting disintegration — all of which provide contaminants a path into the water source.
Many of the reasons for contamination being able to enter a water supply could be interrelated. All too often, aging facilities do not have the resources to maintain quality when a breach occurs. Contaminants enter the water management filtration, and disinfection systems, at a rate higher than treatment can accommodate.
Of the 20,978 boil water advisories recorded from 2012 to 2014 in the U.S. , 53.06% were issued due to a water main break or leak, 14.11% due to low pressure, 13.87% due to confirmed microbiological contaminants, 11.92% due to an unknown cause, and 7.05% due to scheduled maintenance.
Causes from outside the water management facility:
- Sewer overflow and poor waste management that infiltrates into aqueducts and aquifers
- Flooding and storm runoff combines fertilizers, pesticides, chemicals, animal feces, and other impurities with the reservoir or aquifer
- A Waterline or water main break creates a loss of pressure
Causes at the water management facility:
- Water samples that show the presence of E. Coli, fecal indicators, or other bacteria
- Backflow issues and low water pressure create suction of impurities from outside the pipes into the water
- Interruption of treatment that could either be abrupt due to a storm or power outage, or scheduled such as during facility maintenance
- Inadequate disinfection is discovered
- Indication of Cryptosporidium or Giardia presence
Primary Reason for U.S. Boil Water Alerts from 2012–2014
The Effects of Boil Water Advisories
At home, a Boil Water Advisory is a nuisance — requiring you to rearrange your routines in order to make sure everyone has safe water.
If you own or operate a business, not taking the proper precautions during a Boil Water Alert could result in closed doors and a loss of valuable sales.
In hospitals, medical facilities, nursing homes, and any industry that cares for people, water that is pure and safe means life or death.
3 Possible Water Treatment Options During a Boil Water Alert
When a Boil Water Advisory is issued, you have three options to consider: boiling, chemical treatment, and UV-C disinfection.
If boiling, the EPA and CDC recommend you bring the water to a rolling boil for 1 minute (3 minutes at elevations greater than 2,000 meters, or 6,561 feet). Then, allow the water to cool thoroughly before use.
If choosing chemical disinfection, use unscented, plain household chlorine bleach. Proper precautions must be taken to avoid overdosing and chemical mishaps.
UV-C is automatic and chemical free. Unlike boiling and chemical disinfection, it allows personal hygiene, dish washing, food and beverage prep, and cleaning to take place as usual during a Boil Water Alert.
Infection Concerns with Boil Water Advisories
A Boil Water Alert will remain in effect until water testing Indicates that water quality is back in line with EPA safety regulations. Different sets of circumstances are behind every advisory. Unless it’s pre-scheduled for facility or pipe maintenance, there is no way to know how long it will last.
Contaminations that trigger Boil Water Advisories can pose minimal to severe health risks. Since harmful pathogens are often invisible to the naked eye, water may appear perfectly normal coming out of the tap.
Although the U.S. has one of the safest drinking water systems in the world, there are an estimated 4–32 million cases of acute gastrointestinal illness (AGI) per year from public drinking water systems.— CDC, “Magnitude & Burden of Waterborne Disease in the U.S.”
In 2017 alone, there were 6,939 deaths from 13 water transmittable diseases. Of these, 7% were caused by ingested fecal waste in their water.— CDC, “Current Waterborne Disease Burden Data & Gaps”
The pathogens listed below can cause a range of symptoms including headaches, nausea, cramps, diarrhea, and vomiting. Elderly, young, pregnant, and immune-compromised people are at the highest risk for significant health complications and even death.
Inactivating these pathogens is critical when a Boil Water Alert is issued:
With UV-C Disinfection, Avoid the Hassles of Boiling Water During an Advisory
Ultraviolet technology has been recognized for decades as a safe, powerful, rapid, and chemical-free method of disinfection. Germicidal ultraviolet lamps, known as UV-C lamps, emit ultraviolet wavelengths at 254 nanometers. This level is lethal to virtually all bacteria, virus, and cysts, including the pathogens listed above.
The Keys for Successful UV-C Disinfection
In order to effectively disinfect your water, you’ll need a quality constructed system, the correct installation, consistent maintenance, and a properly-sized system for your water volume. Successful disinfection depends on unobstructed ultraviolet wavelengths through the water, and the appropriate dose of UV light needed in order to inactivate the particular organisms. For UV-C to inactivate pathogens, the water must be clear and free of sediment.
When selecting a UV-C water disinfection system for your home or business, consider your disinfection goals, proper evaluation of your water volume, and whether you want continuous or intermittent purification. Small purifiers can operate between 1 and 1,200 gallons per hour. Larger ones can provide 25,000 gallons per hour or more. Our UV Application Specialists can help you determine the proper system to keep your water safe at all times — including during Boil Water Advisories.
