Public Notification & Emergency Communication

Blog Post Template - A-Z Public Notification.png

Public Notification Rule is intended to ensure that consumers will always know if there is a problem with their drinking water. These notices immediately alert consumers if there is a serious problem with their drinking water that may pose a risk to public health. They also notify customers if their water does not meet drinking water standards, the water system fails to test its water, or if the system has been granted a variance (use of less costly technology) or an exemption (more time to comply with a new regulation.) Consumer Confidence reports (CCRs) are an annual report of the status of the drinking water at a facility that are also required. However, CCRs do not necessarily report problems, but a status.

We have 731 resources (and counting) on Public Notification in our Documents Database that provide valuable information on this topic. You can search for documents about how states are responding to health advisories for water systems, ways to prepare for a drought related water shortage, advice for working with news media, boil water advisories during natural disasters, and many other useful guides that will help you to deliver safe and clean water to utility customers. 

To access the wealth of knowledge on Public Notification within our database just select "CATEGORY" in the dropdown then choose "Public Notification." Once you make that selection, a second dropdown will appear where you can choose "HOST," “TYPE,” or “STATE” to narrow the search even further. If you have a specific search term in mind, use the “Keyword Filter” search bar on the right side of the screen.

Learning Lessons from Supply Chain Disruption

Potassium permanganate

One of the most prominent economic impacts to emerge from the COVID-19 pandemic was the breakdown of supply chains for many consumer, medical, and industrial products. Though the shortages of goods such as toilet paper, semiconductor chips, personal protective equipment and more made widespread headlines, the range of items affected spread much wider — including to the supply of critical water treatment chemicals. The American Water Works Association found in November 2021 that 45% of surveyed water utilities were experiencing shortages of water treatment chemicals, among other staffing and supply issues. 

Shortages of chlorine did make news in the summers of 2021 and 2022 due to the difficulty pool-owners had obtaining it to clean their pool water, but the threat it posed to water utilities — where chlorine is a critical component of the treatment and disinfection process — was much less widely known. In 2021, the pandemic spurred the shortage by causing a decrease in production capacity, an increase in demand (largely from a boom of newly-installed pools), and other logistical failures. However, non-COVID factors also played a role in the shortages.

Hurricane Laura, which struck Louisiana in August 2020, severely damaged the BioLab Inc. chemical plant, a major US producer of chlorine. In 2022, the labor dispute between rail workers and rail companies briefly led to an embargo on the rail transport of hazardous materials including chlorine and other water treatment chemicals. While further major disruptions did not occur in 2023, the EPA considers the chlorine supply chain to be “vulnerable to periods of reduced product allocation and/or price increases” and maintains a page tracking the status of chlorine availability and pricing. 

The most severe supply chain disruption in 2023 for water treatment chemicals came right at the start of the year — when a four-alarm fire devastated the Carus Chemical factory in LaSalle, Illinois, on January 11. Carus is the only producer of potassium permanganate in North America, which is used to oxidize contaminants in drinking water. While the company initially warned of  a 3-month outage in its production capacity, potassium permanganate production did not resume at Carus until August. Luckily, overseas imports were able to fill demand after some initial shortages, and the EPA found that supply had stabilized by May.

Other water treatment chemical supply chains that the EPA considered to be disrupted since 2020 include carbon dioxide, sodium hydroxide and hypochlorite, hydrochloric acid, ferric and ferrous chloride, oxygen, and fluorosilicic acid. However, none of these disruptions are considered to be ongoing.

While supply chains of water treatment chemicals have always been susceptible to periods of economic strain, such as the Great Recession of 2007-09, COVID-19 revealed many more risks in the system. According to the EPA’s “Understanding Water Treatment Chemical Supply Chains” report:  

“The supply disruptions that have occurred during the pandemic era revealed a range and intensity of supply chains stressors that had not previously been observed in such a short timeframe. While high-impact events such as a pandemic or repeated extreme weather events concentrated on industrial hubs may have been considered low-probability in previous assessments, supply chain risk planning may have to consider greater frequency and co-occurrence of such high-impact events.”

The most prevalent long-standing threats to the stability of supply chains include natural disasters, equipment failures, logistical problems such as transportation delays, and malicious acts like cyberattacks and sabotage — none of which will stop being a concern even as the pandemic is increasingly behind us. International markets can also be severely affected by trade barriers, armed conflicts, and natural disasters. 

Perhaps the most prominent chemical shortage preceding 2020 was a national shortage of chlorine in 1974. While a single cause of the shortage could not be identified, New York Times reporting at the time cited the new requirement to chlorinate wastewater, the closure of production facilities, and the energy crisis of the 1970s (which was peaking with the 1973-74 oil shock) as likely factors.

For more information on the supply chain history of various water treatment chemicals, the EPA’s supply chain profiles of 46 commonly used chemicals contains shortage histories for 2000-2022, as well as risk profiles for shortages of each chemical. Risk ratings for these chemicals can also be found in the “Understanding Water Treatment Chemical Supply Chains” report.

As for future concerns, chlorine availability could continue to be made vulnerable by natural disasters in the Gulf Coast region. 33% of American chlor-alkali facilities, in which most chlorine is produced, are located along the Gulf Coast, which is both historically prone to hurricanes and under greater threat as climate change intensifies storms. Disruptions in chlorine supply also lead to disruptions in ferric chloride supply, which requires hydrochloric acid. 

The EPA has many resources to assist in preparing for and responding to supply chain challenges. The critical steps to prepare are:

  1. Using federal and state support programs for operational efficiency and cost reduction
  2. Management of supplier relationships
  3. Coordinating with other utilities, state and local agencies, and water sector associations
  4. Instituting operational flexibilities 

To respond to disruptions, the EPA recommends:

  1. Seeking federal support
  2. Communicating with suppliers
  3. Coordinating with partners

Hurricane Season Resources

Blog Post Template - Hurricane Season Preparedness and Recovery.png

Peak hurricane season starts mid-August and typically lasts through October. Here are some resources to help your water utility to weather the storms as best as you can. 

According to the National Hurricane Center, there are five major hazards associated with hurricanes. These hazards include storm surge & storm tide, heavy rainfall & inland flooding, high winds, as well as rip currents and tornadoes. Storm surge can travel several miles inland and can cause dangerous saltwater intrusion in areas with estuaries and bayous. 

Use this Storm Surge Inundation Map from U.S. EPA to view your utility’s hurricane risk, mitigate flood damage, and get real-time coastal storm advisories. Rainfall amounts are not directly related to the strength of tropical cyclones but rather to the speed and size of the storm, as well as the geography of the area. This means that it is important to track the rise of water levels even after the storm has passed and to be prepared for flooding. 

U.S. EPA's Flood Resilience Guide is a helpful resource to know your flooding threat and identify practical mitigation options to protect your assets. Hurricane force winds (74 mph or more) can destroy buildings and cause power outages as debris flies around so emergency managers should plan on having their evacuations complete and their personnel sheltered before the onset of tropical storm-force winds, not hurricane-force winds. Access U.S. EPA's newly updated Power Resilience Guide to learn about strategies water and wastewater utilities can use to increase resilience to power outages.

Hurricane Preparedness for Wastewater Facilities

BlogNewsletter Graphics1.png

As Hurricane Ian left swaths of Florida without water and wastewater services at the end of September, the New York Times was already reporting on potential environmental impacts of the storm hitting South Carolina. Beyond the acute hazards of exposure to untreated wastewater, the biggest concern in hurricane-impacted areas is nutrient pollution and the potential for harmful algal blooms.

As extreme weather events impact larger stretches of the country, the water sector (including regional watershed protection entities) will need to anticipate greater consequences in the emergency response planning process. Florida DEP's Hurricane Preparedness for Domestic Wastewater Facilities and FEMA's Hurricane and Flood Mitigation Handbook for Public Facilities offer some helpful recommendations.

FEMA divides its recommended (primarily anticipatory) mitigation strategies into four categories: elevate or relocate, protect or divert, floodproof, provide redundant systems. The fact sheet identifies which of these strategies are appropriate for each major component of a wastewater facility. For example, installing "backflow prevention devices such as valves on lines that flow into the lift station and emergency overflow lines" is an option for floodproofing a lift station.

FEMA also provides a similar framework for drinking water systems.

Florida DEP's suggestions for before and after a hurricane can provide an update to an existing baseline checklist, particularly for minimizing these concerning downstream impacts. For example, it is recommended to "drain wastewater holding ponds as completely as practical after receiving a hurricane warning" as well as ensure that biosolids for land application have been "spread or stored in a secure manner."

With the frequency and severity of hurricanes and other extreme weather events increasing, facilities may need to adopt new strategies to prevent costly cleanup efforts and even legal battles.

COVID-19 in Wastewater Surveillance

covid.jpg

Over the past two years, researchers have turned to wastewater to find out more about the trajectory of the COVID-19 pandemic.

In September of 2020 the CDC developed the National Wastewater Surveillance System (NWSS) to help monitor and better understand the spread of COVID-19 throughout communities. The NWSS works directly with public health departments to track the presence of the SARS-CoV-2 virus in the wastewater of communities across the country. They are able to do this because humans infected with the SARS-CoV-2 virus shed the virus in their feces making it detectable within community wastewater systems. The CDC has been able to gather a large amount of data because 80 percent of households in the United States are served by municipal wastewater collection systems. Wastewater surveillance programs have been implemented across the country in places like UtahWashington D.C.MassachusettsConnecticut, and Illinois. Programs have also been implemented internationally

Wastewater surveillance technology has proven to be very beneficial to communities because it is able to detect the virus even before people start showing symptoms. This is helpful because once health departments are aware, communities can immediately take stricter precautions to prevent the spread of the virus. You can stay up to date on the presence of COVID-19 in your community by checking the COVID Data Tracker which provides regularly updated information on the presence of SARS-CoV-2 levels in wastewater at testing sites across the country.

Preparing Your Water System for Winter Weather

winter.png

Is your water system prepared for winter this year? The extreme weather that can come with the winter season is only growing more severe as climate change intensifies. Many areas across the country have experienced some of the coldest temperatures they have ever had in the last decade. In this era, winter weather can even impact the most unexpected places. 

The historic winter outbreak that occurred in Southeast Texas earlier this year proves that unexpected winter weather can happen anywhere. The storm caused power outages, broken pipes, and billions of dollars in damage because the state was not prepared for winter weather. Even though you think your utility might not have to worry about preparing for winter because you live in a historically warm climate, it never hurts to be prepared.

Preparing for winter is also a smart financial decision. Water officials say that allowing backflow preventers and outdoor water pipes to freeze can be a costly mistake. Frozen water lines can also cause expensive water leaks. Although winter weather can be intense and unpredictable, there are things that you can do to be more prepared. 

Impacts of Extreme Cold and Winter Weather
Cold weather can bring freezing temperatures, heavy snowfall, and ice storms that can have multiple compounding impacts on a community that may include, but are not limited to: 

  • Pipe breaks throughout the distribution system.
  • Loss of power and communication lines.
  • Limited access to facilities due to icy roads or debris such as downed tree limbs.
  • Reduced workforce due to unsafe travel conditions throughout the service area.
  • Source water quality impacts due to increased amount of road salt in stormwater runoff.
  • Potential flooding risk due to snowpack melt and ice jams (accumulations of ice in rivers or streams).
  • Potential surface water supply challenges as ice and frozen slush can block valves and restrict intakes.
Wastewater Cold Weather Maintenance 
Much like drinking water utilities, wastewater utilities can experience ice formation in various process components and reaction rate changes in chemical, physical, and biological reactions. However, they also experience ones specific to wastewater facilities.

Cold weather can impact the bacteria that many wastewater treatment plants use to treat their wastewater. This is because the bacteria typically perform best between 75 and 100 degrees Fahrenheit and when the temperature dips below that the bacteria struggle to consume the waste. When bacteria slow down their consumption of waste BOD (Biological Oxygen Demand) and COD (Chemical Oxygen Demand) levels in the effluent rise. One way to maintain acceptable effluent levels is by adding additional chemicals through the process of bioaugmentation. 

Strengthen Your Resiliency 
Tips to help prepare your utility: 

  • Make sure all your employees have the proper equipment.
  • Check your supply inventory.
  • Stock up on supplies in case your employees need to stay overnight.
  • Exercise your valves.
  • Weatherproof your booster stations.
  • Note whether your employees have the equipment they need for these conditions.
  • Stock extra fuel.

The 2017 small systems FYI from the Indiana Section of AWWA covers additional winterizing tips for water utilities specifically related to security, hydrants, storage tanks, backflow, emergency preparation, wells, worker needs, and pumping equipment. The U.S. EPA recommends coordinating with your state’s Water/Wastewater Agency Response Network (WARN) if an emergency should arise. 

Customer Communication
Communicating with your customers is an important part of preparing your utility for winter weather. Communicating with customers helps to create a trustworthy relationship, especially during an emergency like an extreme weather event. 

You can help make sure your customers are prepared by sharing resources like information on how to winterize their homes and prevent frozen pipes. You can also draft water advisory messages ahead of time to ensure they follow public information protocols and have appropriate distribution channels.

Defend Your Water System Against Drought

drought-water-cracked.jpg

Many states across the United States are currently experiencing one of the worst droughts in American history. Some are even experiencing a "megadrought", meaning that they have been experiencing drought conditions for many years. Climate change also exacerbates drought conditions by increasing the average global temperature and causing irregular weather patterns. Westerns states such as CaliforniaArizonaMontanaNevadaNew Mexico, and Idaho are experiencing some of the most extreme effects. Drought is particularly devastating because it is slow coming but its effects are widespread.

Increased drought conditions can result in:

  • Loss of water pressure and supply 
  • Poor water quality 
  • Limited access to alternative water sources 
  • Increased customer demand 
  • Increased costs and reduced revenues 

For example, in Nevada, the drought has had disastrous impacts on Lake Mead, the largest water reservoir in the United States that currently provides water for over 20 million people across California, Nevada, Arizona, and some of Mexico. The reservoir is now at the lowest it has been since it was filled in 1937 and the situation is so extreme that the federal government is expected to declare an official Lake Mead shortage by the end of the summer. Drought can also negatively impact drinking water providers that rely on lakes because they can increase the number of algal blooms in freshwater. Algal blooms not only contain chemicals that are toxic to humans but large amounts of algae can also clog water filters and damage the water treatment process. 

A total of 31 states are currently experiencing moderate to severe drought across the country. Research also shows that the drought has become progressively worse over the past few decades. The U.S. Drought Monitor website has a feature that allows you to monitor the level of drought happening in your area.

Like most natural disasters, rural and low-income communities are often hit the hardest by drought conditions because of their lack of access to resources and infrastructure. Rural farmers are also greatly impacted by drought because of the lack of water available for irrigation, making it very difficult to support themselves. 

Droughts are a public health issue because they affect access to clean and safe drinking water. Practicing emergency response and preparedness is the best way to minimize severe impacts from drought. To avoid serious impacts from droughts, water utilities should:

  1. Conduct observation and monitoring 
  2. Practice planning and preparedness  
  3. Predict and forecast 
  4. Maintain good communication and outreach with customers 
  5. Use interdisciplinary research and applications

Preventing & Responding to Security Threats

Facility and infrastructural security are an important component of any emergency response plan. Whether the outcome can result in vandalism, theft, terrorism, or a threat to staff or community safety, suspicious activity should always be taken seriously. When the city of Woodland Hills was alerted of trespassing at their water storage tank, the utility promptly issued a boil order until they could confirm that their water was safe to drink. These actions prevented any potential harm due to contamination leaving community members safe and reassured that their utility was taking an active role in water security. Evaluating risk to malevolent acts will allow your system to initiate or upgrade preventive measures and develop an appropriate response plan to protect staff and the community.

To prevent malevolent acts, start by taking an assessment of your facility’s vulnerabilities. Consider entry points, security code accessibility, chemical tanks, storage tanks, vehicles, utility equipment, hazardous chemicals, and infrastructure within the distribution or collection system. Infrastructure essential to operations and limited in redundancy or identified to be at greater risk to malevolent acts may require more meticulous security measures. To assess physical security threats, check out the Security Vulnerability Self-Assessment Guide for Small Drinking water Systems.

The goal in a vulnerability assessment is to determine where prevention measures can be implemented and develop a response plan to suspicious activity.  According to the Minnesota Department of Health, many facilities increase security by locking entry points, using external lighting, posting warning signs, requesting law enforcement patrol, fencing in critical infrastructure, or installing motion sensors, alarm systems, and video cameras. Once all preventive measures have been taken, develop a response protocol for each potential threat. The Association of State Drinking Water Administrators has developed response guidelines for security violations. In each response scenario, utilities should plan for how they can maintain internal, interagency, and external communication.

Utilities should practice emergency response exercises regularly and keep track of necessary changes to response protocols. During these exercises reserve time to monitor which staff have access to key entry points at the utility. Successful security programs will also build and maintain a close relationship with local law enforcement. This relationship will allow utilities to respond swiftly and efficiently in coordination with law enforcement when suspicious activity does occur.

Remember that final goal of these measures is to prevent any interruption in services, damage to infrastructure, and safety threats to staff and the community. For more information on Malevolent Acts check out the EPA’s Baseline Information on Malevolent Acts for Community Water Systems.

ISAWWA COVID-19 Utility Impact Survey

Specify Alternate Text

To assess management approaches and concerns utilities have adopted in response to the COVID-19 pandemic, the Illinois Section of the American Water Works Association (ISAWWA) released a utility survey to their membership via email on April 3, 2020. Available for one week, 141 members responded with 139 of these respondents representing public water or wastewater systems. Eleven survey questions focused on operational, managerial, and financial changes implemented in response to the pandemic as well as system concerns and needs moving forward. Three additional questions gathered information on utility demographics. Results from the survey can be found in the report: COVID-19 Impact on Utilities. In this blog we will highlight some of the key findings below.

The report indicates that the primary concerns for Illinois utilities focus on maintaining staff health, staff availability, and the continuity of operations. To respond to the pandemic, many systems have implemented staff scheduling changes, split shifts, and the reduction of staffing hours. The survey report goes on to note how other changes are being implemented and how those changes are impacting operations. Regarding revenue, many systems believe it is still too early to understand the full financial impact of the pandemic and have not begun planning for worst-case scenarios. Of those who have noticed changes in revenue, few have witnessed a positive impact on finances. The majority note that they are experiencing lowered commercial water use, an increase in non-payments, cuts to capital projects, or hiring freezes. Emergency response plans offer an effective way to mitigate many pandemic challenges, however the survey notes that only 56% of respondents are developing plans.

Additional questions from the report elucidate the training needs identified by respondents and how utilities are complying with an order by the Illinois Commerce Commission to discontinue water shutoffs.

Of notable interest to small systems, the report includes a section to highlight how system size impacts pandemic response and concerns. To develop these size related trends, the ISAWWA asked respondents whether they represented a small system serving a population of 5,000 or fewer, a medium system serving between 5,001 to 50,000, or a large system serving greater than 50,001. The report reflects that small systems generally have less capacity to respond to the pandemic likely as a result of fewer employees, fewer resources, and the use of a single staff member to maintain a large portion of the system. On the other end, though large systems may have a greater capacity to address the pandemic, they must also overcome the challenges that result from managing a greater number of staff members. Small systems may have fewer challenges related to staff management, however they must also plan for absenteeism more carefully.

For a more detailed review of the survey results, we recommend reviewing the report for yourself. Reading utility responses, concerns, and approaches to managing the virus may assist your system in planning for future challenges and concerns. Visit our web page COVID-19 Resources for Water Systems to find clear and concise information, tools, and resources to make managing these pandemic challenges a little easier.
