Cybersecurity: Israeli-made Components Become a Target for Hackers

The critical importance of cybersecurity in water treatment facilities has come into sharp focus lately with a slew of attacks in just a few weeks. Worldwide there have been multiple instances of cyberattacks targeting these essential services, underscoring the need for enhanced digital defenses for our most precious resources. These incidents not only highlight the vulnerabilities of water systems to cyber threats but also the evolving nature of these digital threats.

Just days ago on December 7th, a water treatment plant in the Irish city of Erris faced a cyberattack that left about 180 residences without water for two days. This attack was linked to the use of equipment from Israeli companies, targeted by a group believed to be from Iran called CyberAv3ngers. In the U.S., the Municipal Water Authority of Aliquippa, Pennsylvania, also experienced a breach by this group, which managed to control a device at a remote water station.

The CyberAv3ngers, a group believed to be linked to Iran’s Islamic Revolutionary Guard Corps, is engaging in cyberattacks on critical infrastructure, including water treatment facilities, as part of a broader geopolitical strategy. Their actions appear to be motivated by the desire to undermine Israel, by targeting entities using Israeli-made equipment. It appears these attacks are not just about causing immediate disruption but are also part of a larger messaging effort to influence international perceptions and exert geopolitical pressure.

These incidents underscore the challenges water treatment facilities face in securing critical infrastructure. The CyberAv3ngers’ attacks, though not known for their sophistication, demonstrate the vulnerability of facilities that neglect basic security measures. Furthermore, the U.S. Environmental Protection Agency (EPA) has been scrutinized for insufficient resources and personnel to adequately address these cybersecurity challenges.

The Biden administration announced plans to improve the digital defenses of public water systems earlier this year, with a focus on industry accountability. This includes novel rules placing more responsibility for securing water facilities at the state level. However, experts like Mark Montgomery, former executive director of the Cyberspace Solarium Commission, criticize these measures as inadequate, pointing out that both the EPA and states lack the necessary resources. The water treatment industry also expressed concerns, with the American Water Works Association highlighting practical problems in the government’s approach.

The incidents revealed technical vulnerabilities, such as poor security practices and outdated software. For example, the breach in Pennsylvania exploited poor security practices, including an exposed device to the internet and weak password protocols. Cybersecurity experts recommend not only patching these vulnerabilities but also adopting robust security measures like multi-factor authentication and regular security audits. In this digital age, cybersecurity is an integral component of water treatment operations. Facilities must stay abreast of the latest threats and ensure that their systems are fortified against potential breaches. This includes regular updates to security protocols, employee training in cybersecurity best practices, and collaboration with government agencies for guidance and support.

The recent cyberattacks on water treatment plants in Ireland and the U.S. serve as a wake-up call for the industry. As cyber threats evolve, so must the strategies to combat them. This requires a concerted effort from both the government and the water treatment industry to invest in stronger cybersecurity measures, enhance employee training, and develop more resilient infrastructure. The safety and reliability of water services depend on the industry’s ability to adapt and respond to these digital threats effectively.

Joe Rogan Wades Into Fluoridated Water

Desirée Sykes

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.

cities are adopting to address public health crises.

Meanwhile, Las Vegas has encountered similar issues, with
water scientists detecting increased concentrations of party drugs and
medications in the water following major events like the Electric Daisy
Carnival and the NFL draft. These findings are particularly concerning given
the city’s reliance on recycling all indoor water, including sewage, to
mitigate the effects of the ongoing megadrought in the West. While the
treatment processes in Southern Nevada are deemed effective in removing these
drugs from the water, the long-term ecological impacts, especially on fish and
marine life, remain a source of concern.

PhACs, identified as emerging micropollutants, originate
from various sources, including the pharmaceutical industry, hospitals, and
agricultural runoff. Found in concentrations ranging from nanograms to
micrograms per liter in wastewater treatment plant effluents, PhACs can cause
acute and chronic harm to wildlife. Addressing this issue, wastewater treatment
technologies such as bioremediation, adsorption, and advanced oxidation
processes have been explored for their efficacy in removing PhACs. Notably, membrane
bioreactors (MBRs) have shown removal efficiencies of up to 99%, presenting a
promising solution for minimizing pharmaceutical pollution.

The advent of these pollutants in water systems highlights

Addressing Saltwater Intrusion: A Technical Perspective

Nate Talley

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.
