White House Announces Nearly $6 Billion for Water Infrastructure

Water Infrastructure

This week the Biden administration announced a $5.8 billion investment towards improving the nation’s ailing water infrastructure, part of the bipartisan 2021 legislation allocating $50 billion for water infrastructure enhancements. These funds aim to address the critical needs of modernizing drinking water systems and wastewater management across the country. The American Society of Civil Engineers (ASCE) has long highlighted the deteriorating state of U.S. water systems, assigning a C- rating to drinking water infrastructure and a D+ to wastewater systems in 2021. This situation underscores the urgent need for comprehensive upgrades to safeguard public health and ensure environmental sustainability.  

The allocated funds will facilitate projects to eliminate lead pipes, enhance water treatment processes, and expand access to safe drinking water, particularly in underserved communities. The initiative not only focuses on replacing hazardous lead service lines but also addresses the challenges posed by climate change, such as saltwater intrusion and increased sediment and pollutant runoff, which compromise water quality and availability. 

The federal government’s strategy involves distributing funds through the Clean Water and Drinking Water State Revolving Fund programs, allowing states, territories, and tribes to prioritize and manage projects according to their specific needs. This decentralized approach ensures that the unique water infrastructure challenges of each region can be addressed effectively, from the urban centers grappling with lead contamination to rural areas facing water scarcity. 

However, the endeavor to revamp the nation’s water infrastructure is not without its complexities. Past efforts, like those in Flint, Michigan, have demonstrated the risks associated with transitioning water sources and the dire consequences of inadequate corrosion control measures. Flint’s crisis, where elevated blood lead levels were discovered in residents due to corroded pipes, is a stark reminder of the critical need for continued investment in water treatment and distribution. 

Eastern Kentucky emerges as a real-life example, underscoring the urgent need for infrastructure renewal. A story from Lexington NPR station WEKU earlier this week highlights that the region, already accustomed to dealing with water issues, faced unprecedented hardship following a historic flood in 2022 that devastated drinking water systems. This catastrophe revealed the true fragility of our aging infrastructure, with some systems relying on pipes that are 70 to 100 years old. The situation illustrates the broader challenges faced nationwide in ensuring reliable access to clean water amidst both natural disasters and aging facilities. 

The commitment demonstrated by this bipartisan bill shows, at the least, an across-the-aisle acknowledgment of the rapidly crumbling infrastructure in both urban and rural areas. For water treatment professionals, this significant federal investment presents an opportunity to address decades old concerns like lead pipes and rural access, as well as modernizing treatment processes to keep beautiful clean water flowing for all Americans.

Green Desalination

Water testing

A few weeks ago we covered research published in the Society of Petroleum Engineers’ Journal of Petroleum Technology that laid out the possibilities of mining rare earth minerals from Produced Water, a byproduct of oil and gas production. This week we delve into a company that’s betting on the profitability of another toxic byproduct: Desalination brine. The combination of high operational costs, environmental impact, and the logistical challenges associated with brine disposal has limited the widespread adoption of desalination technology, especially in regions where cheaper alternatives are available. The surge in desalination as a solution to global water shortages has brought about environmental concerns, particularly regarding the energy-intensive processes involved and the disposal of brine byproducts.  
 
However, a pioneering initiative by the startup Capture6 is set to redefine the narrative by integrating carbon capture technology with seawater desalination efforts, promising a sustainable future for both water supply and carbon reduction. Desalination plants, crucial for supplying fresh water in drought-prone regions, face criticism for their environmental impact, notably the production of brine—a toxic byproduct harmful to marine ecosystems—and significant energy consumption contributing to greenhouse gas emissions. The challenge is twofold: supplying fresh water sustainably and mitigating the carbon footprint of such essential operations. Capture6’s venture, dubbed Project Octopus, presents an innovative approach to these challenges. The project, to be piloted in South Korea, aims to capture carbon dioxide from the air using brine from desalination processes. This not only offers a method to reduce the carbon footprint but also tackles the issue of brine disposal by turning it into a resource for carbon sequestration. Furthermore, the process yields an additional supply of fresh water, addressing the water scarcity problem head-on. 

Project Octopus leverages a liquid sorbent derived from the salt in desalination brine to react with atmospheric CO2, producing a stable, limestone-like compound that securely locks away the carbon. This synergy between desalination and direct air capture (DAC) technology could revolutionize how industries perceive and manage their waste, transforming it from an environmental liability into a valuable asset in the fight against climate change. Despite the potential benefits, the energy requirements for DAC and desalination are considerable, with current operations largely dependent on fossil fuels. The environmental viability of such projects hinges on advances in energy efficiency and the transition to renewable energy sources to power these processes. Critics and researchers alike emphasize the importance of ensuring that the net impact of integrated facilities like Project Octopus is a reduction in overall emissions and not merely a redistribution of environmental burdens. 

The ambition of Capture6, supported by collaborations with South Korean water utility K-water and wastewater treatment company BKT, reflects a growing recognition of the need for multidisciplinary solutions to climate and water challenges. While the pilot project’s scale is modest, its aim to expand significantly by 2026 illustrates the potential for scalable solutions that can have a meaningful impact on carbon reduction and water reclamation. Capture6’s innovative integration of carbon capture with desalination waste treatment stands as a beacon of how technology can bridge the gap between industrial necessities and environmental stewardship. As this and similar projects progress, they offer hope for sustainable practices that can simultaneously address the urgent needs for clean water and carbon reduction. For water treatment professionals, this represents a burgeoning field ripe with opportunities for innovation, collaboration, and leadership in environmental conservation.

Addressing Saltwater Intrusion: A Technical Perspective

Salt Water Intrusive

Water treatment technicians, tasked with safeguarding the quality of our aquatic resources, are facing a subtle yet significant threat in the Mississippi River. Beyond the familiar challenges presented by the sea, an insidious issue arises: the progressive intrusion of saltwater into the delta. 

Due to long lasting drought upstream, saltwater is moving up the Mississippi River. The denser saltwater flows underneath the less dense freshwater, creating a two-level flow pattern in a wedge-shaped formation. The saltwater wedge is pushed upstream by the tides and by the prevailing winds. The Mississippi River is primarily a freshwater river, so the intrusion of saltwater is likely to be highly detrimental for local drinking water and infrastructure.  

Currently the Army Corps of Engineers has constructed underwater sills on the river at a number of locations, including near Head of Passes, Louisiana. Underwater sills are typically constructed of rock or concrete and are placed across the riverbed. They are designed to slow the upstream movement of saltwater by increasing the resistance to flow. The Corps also operates a number of reservoirs on the river that allow it to release fresh water to combat the intrusion, but these are not permanent solutions.  

The good news is the distance required for saltwater to cause problems in the Mississippi’s infrastructural water intakes is quite far, likely tens to hundreds of miles. However, the salinity of the saltwater is a critical factor. Generally, freshwater sources like the Mississippi River have low salinity, so even a small increase in salt content due to seawater intrusion can have adverse effects on drinking water quality and the infrastructure that relies on freshwater for local towns and cities. Aside from drinking water and infrastructure concerns, saltwater intrusion can also have detrimental effects on the local ecosystems, aquatic life, and vegetation that depend on freshwater. Salt can also slowly corrode pipes, making this a potentially long-lasting infrastructural problem. 

In addressing the challenge, both the government of Louisiana and the Army Corps are shifting their focus towards substantial initiatives. This includes the potential implementation of reverse osmosis units to extract salt from drinking water, the construction of a 55-foot-tall underwater levee to impede the encroachment of the saltwater wedge, and a rather bold strategy involving the transportation of millions of gallons of freshwater downstream to alleviate salt overload in water systems. 

From maintaining reverse osmosis units to supervising the structural integrity of the proposed underwater levee and managing freshwater transportation logistics, the expertise of technicians is crucial. These expert contributions ensure the efficacy of these interventions and pave the way toward innovation, resilience, and safeguarding our communities against the nuanced threat of saltwater intrusion. Through strategic, targeted efforts, we can protect our water systems, maintaining their safety and functionality amidst this lurking challenge.

Joe Rogan Wades Into Fluoridated Water

Fluoridated Drinking Water

Few public figures bring controversy to otherwise mundane subjects more than Joe Rogan, host of the chart-topping podcast The Joe Rogan Experience, claiming 14.9 million subscribers. A recently released episode of his show touched on a subject most people would flee from had it come up in conversation at a party, lest they be hemorrhaged by boredom: municipal tap water. More specifically the use of fluoride in the vast majority of America’s drinking water.  

In the podcast, released early September on his exclusive platform Spotify, Rogan questioned the need, and even the motive behind the use of fluoride in the general public’s main source of hydration. “There’s some real disputes about fluoride in the water” the ex-Fear Factor host remarked “Exposure to fluoride lowers your IQ… it literally makes you dumber. How much better is it than brushing your teeth? We’re forcing people to take care of their teeth and everybody else is going to lose IQ points?”  

While he couches these statements with his customary “I’m not entirely informed on the matter” disclaimer, he brings up an issue that’s controversy spans decades.  

For years fluoride in water has been igniting debates and inquiries into its efficacy, safety, and ethical implications. Dating back to the mid-20th century, the practice of adding fluoride to public water supplies aimed to enhance dental health, but its controversial nature raises serious questions concerning health risks, ethical considerations, and the overall effectiveness of this intervention. 

Several studies have investigated the relationship between fluoride exposure, primarily from drinking water, and cognitive function or intelligence quotient (IQ). Worldwide research, and particularly studies conducted in regions with higher naturally occurring fluoride levels in water, has suggested a potential association between elevated fluoride exposure and lower IQ scores in children. 

Within the realm of water treatment, proponents of fluoridation emphasize its potential to significantly reduce dental cavities and tooth decay, particularly in children. Esteemed organizations like the American Dental Association (ADA) and the World Health Organization support it. But critics voice concerns regarding potential health risks associated with prolonged exposure to elevated fluoride levels. Skepticism persists concerning the link between excess fluoride intake and health problems such as skeletal fluorosis, prompting a reevaluation of recommended fluoride levels for water treatment processes. 

The debate surrounding water fluoridation hinges on a complex weighing of benefits and potential drawbacks. Critics argue that the practice of fluoridating water, despite its intended dental benefits, raises valid concerns regarding individual autonomy and consent. Adding fluoride to a communal water supply essentially amounts to a forced medical intervention affecting everyone, regardless of age, health condition, or informed choice. The lack of personalized dosage and potential overexposure, especially for vulnerable groups like infants and the elderly, is a worrisome aspect. Moreover, considering the availability of alternative fluoride sources such as toothpaste and mouth rinses, some question the necessity of a mass fluoridation approach. As research suggests potential links between fluoride exposure and cognitive health issues, skeptics emphasize the need for a cautious approach. In weighing these factors, they argue for a reconsideration of water fluoridation, advocating for individual agency, informed consent, and a tailored approach to dental health that respects individual rights and minimizes potential health risks.

Drinking Water Contamination Incidents: Is Your PR Team Ready?

City Water Contamination

Most water treatment professionals are used to the day-to-day analysis of water and maintenance that comes with the job. Howbeit, not all are prepared for a drinking water contamination incident such as E.coli. Is your team ready to respond when an emergency strikes?

Unfortunately, this topic hits close to home for me. As a resident of Tyler and customer of TWU, I was quick to learn about a boil notice issued by the City of Tyler for E.coli contamination, and of course, was mildly horrified. The boil notice didn’t last long, though; the city lifted it the following day at 11 am. After talking with other residents and customers of TWU, to my surprise, this was not the first time the city has had water quality issues. Feeling concerned, I reached out to the City and asked if it was normal after E.coli detection in a water sample to only have a 24-hour boil notice for customers?

The City of Tyler released this statement:

“It is not normal for us to have a water sample test positive for E.coli.  We take dozens of samples everyday at various points around the City. Those samples got to the North East Texas Public Heath Regional Laboratory in Tyler to be tested according to TCEQ requirements.  

The boil water notice had to be issued  as the result of a single routine sample site tested showing the presence of e. coli, followed by a repeat sample at the same site in Central Tyler showing the presence of total coliform. E. coli was only found in one sample site out of many tested.   

Tyler water meets and exceeds all State and Federal standards. Our water system is safe.”

Famed environmental activist, Erin Brockovich, has long expressed concerns over the safety of the city’s water. In 2015, responding to another TWU water contamination incident, she posted on Facebook that the City was downplaying the incident. City officials were quick to respond to her post, “Our drinking water is the No. 1 priority of this department,” Assistant City Manager Susan Guthrie said. “We followed exactly what TCEQ requires us to do.”

No matter your opinion on the safety of Tyler’s water, the fact remains that the city was quick to respond in both situations. When disaster strikes, water facilities need to be prepared to react assuredly and quickly to ease customers’ minds. To avoid being caught unprepared, the EPA offers this guidance on how to react in situations like these. The City of Tyler followed the guidance of The Distribution System Contamination Response Procedure (DSCRP) outlined by the EPA, does your facility have a plan in place to do the same?

In recent years, water treatment professionals across the globe have faced an alarming surge in the frequency and severity of flooding events. These rising tides are causing significant challenges for wastewater treatment facilities. As the demand for effective and resilient wastewater management grows, it is crucial to understand the profound impact flooding has on these critical infrastructure components.

Extreme weather events, such as hurricanes, torrential rainfall, and storm surges, have surged over the last decade. These events have made flooding an increasingly common occurrence in both coastal and inland regions. According to the National Oceanic and Atmospheric Administration (NOAA), the United States has experienced a 20% increase in heavy rainfall events over the last century, with the North East region seeing up to a 55% increase.

One of the most immediate and tangible effects of flooding on wastewater treatment facilities is damage to critical infrastructure. Floodwater can inundate treatment plants, causing electrical systems to short-circuit, damaging pumps and motors, and compromising the structural integrity of facilities. The repair and replacement costs can be astronomical, straining budgets and resources.

Flooding events can overwhelm treatment systems, leading to the release of partially treated or untreated wastewater into water bodies. This discharge can contain a cocktail of pollutants, including bacteria, chemicals, and nutrients, posing significant health and environmental risks. The contamination of water bodies can lead to the spread of waterborne diseases, harm aquatic ecosystems, and impact drinking water sources downstream.

Wastewater treatment plants often rely on a delicate balance of biological processes, chemical treatments, and mechanical components. Flooding can disrupt this delicate equilibrium, leading to operational failures. In some cases, plants may need to be shut down temporarily to prevent further damage, which can lead to service interruptions and reduced capacity during flood events.

As water treatment professionals grapple with the mounting challenges posed by flooding to wastewater treatment facilities, it is imperative to adopt proactive strategies and invest in resilient infrastructure. In doing so, we can safeguard public health, protect the environment, and ensure the continued provision of clean water for our communities. The collective efforts of the water treatment industry will play a pivotal role in addressing this critical issue.
