"The present study found that approximately 63% of the hotels which were inspected following a Legionnaires' disease case notification were found to be colonized with Legionella spp. The study also evaluated the significant factors that contribute to the maintenance, management and disinfection of water distribution systems, including the successful implementation of WSPs to improve hotel water supply and sanitation systems. Chemical treatment and the monitoring of drinking water quality, including chlorine disinfection, pH adjustment, and water temperature control of hot water systems are recommended as control measures in water safety plans, in conjunction with other procedures. It has also been found that antiquated hotel buildings are at increased risk in terms of the safety and quality of the water in their distribution systems. To conclude, risk assessment, environmental monitoring and disinfection of water systems, as well as the implementation of preventive control measures (WSPs) are the key elements for preventing contamination by pathogenic microorganisms in large public and private water distribution systems."

The Aging Water Infrastructure (AWI) research program is part of EPA's larger effort called the Sustainable Water Infrastructure (SI) initiative. The SI initiative brings together drinking water and wastewater utility managers; trade associations; local watershed protection organizations; and federal, state, and local officials to ensure that all components of our nation's water infrastructure….drinking water treatment plants, drinking water distribution lines, sewer lines, and storage facilities….meet future needs. The AWI research program supports the four priority areas of the SI initiative's strategy: (1) Better Management - moving beyond compliance to sustainability and improved performance, (2) Full-cost Pricing - helping utilities to recognize the full cost of providing service over the long term, (3) Water Efficiency - promoting water efficiency in the residential and commercial sectors, (4) Watershed Approach - integrating watershed management principles and tools into utility planning and management practices. The driving force behind the SI initiative and the AWI research program is the "Clean Water and Drinking Water Infrastructure Gap Analysis." In this report, EPA estimated that if operation, maintenance, and capital investment remain at current levels, the potential funding shortage for drinking water and wastewater infrastructure could exceed $500 billion by 2020.

DRIVER-SCARCITY The Industrial Revolutions improved living standards for people in most nations where technology proliferated.[1] Populations in modern societies are not overly concerned with accessing food or water on a daily basis. In particular, the availability of clean, freshwater is a reasonable expectation throughout the modern world. However, a growing lack of water ("water scarcity"), propelled by continued technological advancement and high demand, is creating a global crisis. This resource scarcity will change long-held expectations and demonstrate the capacity to disrupt the security and stability of entire regions. This Article examines the global state of freshwater scarcity[2] and the often-neglected linkages of water scarcity to economic, social, political, legal, and security consequences arising from disruptions, failures, or attacks on water access and distribution systems.[3] Our research concentrates on examples of the impacts of water scarcity from past and present utilizing selected examples from North America, the Middle East, South Asia, and Africa. We contend that poorly understood links between access to adequate water and national stability pose severe global security risks, especially if technological and policy correctives are not implemented to increase water resiliency and ensure availability and access.

"For cities to catch up, they need to apply a data-driven approach similar to what farms are using to more effectively grow crops. Cities must start supporting urban agriculture in targeted ways that work with the urban agriculture industry to transform our current food production and distribution systems into smarter, more localized, and more resilient networks."

DRIVER-POLITICS Water Politics Limited, a geopolitical risk advisory and consulting firm, found that water scarcity could lead to conflict or political instability in many countries. Sources including the Euphrates, Tigris, Jordan, Nile, Danube, and Okavango rivers as well as the Tibetan watershed and resources will become insufficient to support the surrounding areas. These sources currently provide water to dozens of countries across Europe, the Middle East, Asia, and Africa. Water scarcity will therefore affect communities across the globe. Importantly, it may spark conflict over remaining water resources, within a nation or even between nations. Anya Groner at The Atlantic points to evidence of past conflicts that have revolved around water. These include the riots in Cape Town, South Africa, in 2012, which responded to inequality in the distribution of water resources.

DRIVER-TREATMENT-TTHM-POLITICAL CLASS-ACTION LAWSUIT Rapid detection of the total trihalomethanes (TTHM) in treated drinking water is essential for compliance with the Environmental Protection Agency's (EPA) Stage 2 Disinfectants and Disinfection Byproducts (DBP) Rule, which limits the maximum contaminant level of TTHM in drinking water. The current detection method for TTHM determination involves sending samples to EPA certified laboratories for gas chromatography analysis; a method that is both expensive and time consuming. In the Phase I, Agave BioSystems demonstrated proof of concept for a sensitive colorimetric TTHM detection system based on a modified Fujiwara reaction, which can be integrated into a portable field sensor. This assay system utilizes a modified Fujiwara reaction to yield a detectable color product that correlates directly to the TTHM levels of the water sample. In this Phase II, Agave BioSystems proposes to construct a compact and portable rapid response TTHM water monitoring system for field use. BENEFIT: TTHM is linked to increased rates of bladder and colorectal cancers, and several studies link TTHM to heart, liver, and central nervous system damage. The EPA estimates that lowering TTHM levels in as few as 1,200 small drinking water systems could prevent up to 20 cases of bladder cancer per year, resulting in economic benefits of up to $110 million per year. Another documented health risk is the increased rate of miscarriage and congenital birth defects in areas with high TTHM levels. A Virginia based class action lawsuit seeking more than $1 billion in damages, claims that peak TTHM occurrences in one water distribution system may have led to multiple miscarriages. A cost effective and easy to use field portable sensor, such as the one proposed by Agave BioSystems, would enable drinking water delivery systems of any size to effectively monitor the levels of TTHM in their water supply on a more frequent basis, and allow proactively treating

DRIVER-TREATMENT-WATER-INFRASTRUCTURE-CHEMISTRY-CHLORAMINE One new option that communities with ammonia problems have is biological filtration. This is a safe, chemical-free, method of removing ammonia. In a biological filtration facility, one of the stages of filtration is to pass the water through a special filter that is full of nitrifying bacteria. These bacteria take in the ammonia and some oxygen and perform a bio-oxidation reaction. They oxidize the ammonia into nitrite NH3 + O2 -> NO2- + 3H+ Then further oxidize that into nitrate, NO2- + H2O -> NO3- + 2H+. The bacteria gain energy from these reactions and are specialized to do them very efficiently. This process is part of the natural nitrogen cycle and does not produce any harmful byproducts. The nitrate that is produced by this process can easily be removed from the water by the reverse osmosis membrane in the final stage of the filtration process. The reaction between chlorine and ammonia can be written as NH3 +HOCl -> NH2Cl + H2O. In this chemical equation, NH3 is ammonia and HOCl is hypochlorous acid which is formed when the chlorine is first dissolved in the water. The primary result of this chemical reaction is NH2Cl, a chemical known as chloramine. Chloramine is a disinfectant like chlorine, it is a weaker disinfectant than chlorine but it lasts much longer in water. The chlorine concentration in water can gradually decrease as the chlorine evaporates out but chloramine does not do this. This makes it useful for making sure water stays disinfected throughout drinking water distribution systems. In areas where there is no, or very little, ammonia in the raw water treatment facilities might still want to use chloramine for this purpose. After chlorinating (disinfecting) the water, as the last step in the treatment process, they add ammonia and more chlorine to the water so that they react and create chloramine.

Just when you thought QE (qualitative easing) was getting out of hand, the Federal Reserve is now looking to create a digital Federal Reserve Note. The language of the proposed bill is monumental. > "The bill is called the "Digital Asset Market Structure and Investor Protection Act" ("Digital Asset Bill"). And for the majority, it sets out future rules for crypto. However, hidden in this bill, changes to the foundation of the Dollar are proposed." > "...the Federal Reserve System is authorized to issue digital versions of Federal reserve notes in addition to current physical Federal reserve notes. Further, the Board of Governors of the Federal Reserve System, after consultation with the Secretary of the Treasury, is authorized to use distributed ledger technology for the creation, distribution and recordation of all transactions involving digital Federal reserve notes." > BitDollars??

"The defining characteristic of this new version of the creative class may not be where it lives, but its ability to live anywhere it wants. Put differently, people move to certain cities in search of better-paying jobs, but it's now possible to earn high (if not the highest) salaries from almost anywhere. That has been true in certain smaller cities in recent years (Austin and Denver in the United States, for example, and Manchester and Leeds in Britain). To a lesser extent, it has also been true for people who chose not to live in cities at all." Workers hold the power and they need to be able to live and work where they want when they want. We're very reliant on humans, we need to make them valued and show that we are investing in the things they care about.

Here, we assess the lasting impact of the pandemic on labor demand, the mix of occupations, and the workforce skills required in eight countries with diverse economic and labor market models: China, France, Germany, India, Japan, Spain, the United Kingdom, and the United States. Together, these eight countries account for almost half the global population and 62 percent of GDP. Another study that shows how unhappy workers are and that they're squarely in the drivers seat.

Article reviews how supply chain problems are more than bottlenecks at that ports. Lack of truck drivers and availalbility of rail contribute to delays. The article mentions a lot of things that need to be addressed before commerce flows like it once was. A key takeawy is the interconnectivity of ports with other elements of the entire transportation and supply distribution system.

DRIVER-MATERIALS-INFRASTRUCTURE Municipal pipe market spending makes up 30 percent of overall utility CAPEX for water infrastructure. In part, to address aging pipes, bursts, and other leakage management issues, the pipe market is turning to new materials (plastic) and new technologies (trenchless). More than $234 billion (USD) of capital expenditures (CAPEX) are forecasted over the next decade to address aging municipal water and wastewater pipe network infrastructure, according to Bluefield's forecasts. Precipitated by decades of underinvestment, municipal utilities are under increasing pressure to address deteriorating linear assets at a faster pace. Water losses through leaks for U.S. utilities average 15 percent annually, with some cities, towns, and communities losing more than half of all water pumped and treated for distribution to customers. As a result, rehabilitation of existing pipes is the fastest growing spend category, increasing annually from $253 million in 2019 to $576 million by 2028. Network expansions, particularly in high population growth across the sunbelt states (e.g. Texas and Arizona), will drive the lion's share of spending on new build.

"Installing chlorine booster stations at strategic network locations or increasing the outlet disinfectant dose directly at the sources are among commonly used measures to increase disinfectant residuals throughout the network [29]. To test the network robustness to lower demand, the chlorine concentrations at the outlet of each of the three WTPs were increased to 2 mg/L. This allowed for investigating the potential of increasing chlorine dosage at the WTPs to compensate for the performance degradation under water conservation scenarios. "

We all have a futuristic vision of lonely robot trucks running alone through a dark desert night in our heads. But, in reality, the first automated commercial vehicle you see "in the wild," will most likely be a truck or van running in a controlled area - possibly under some sort of remote human control or monitoring. For most of us, this probably will be some sort of airport or hotel shuttle bus, running a dedicated route on a dedicated timetable, performing a monotonous, but demanding, task over and over again.

usted iron pipes can react with residual disinfectants in drinking water distribution systems to produce carcinogenic hexavalent chromium in drinking water, reports a study by engineers at UC Riverside. Chromium is a metal that occurs naturally in the soil and groundwater.

"This book tells a tale of innovation, disruption, and transformation. Mobile money, e-money, e-float, e-wallets, mobile banking, however you characterise it, is not just a cool app. It s a killer app, the first for mobile phones in the developing world. It s also a disruptive innovation that threatens incumbent businesses and is sparking new business formation and entrepreneurship. Nowhere is this mobile money phenomenon more prevalent and successful than in Kenya. In five years, 19 million Kenyans, more than 70% of the adult population, have signed up for mobile money services. Fifteen million are customers of M-PESA ( M for Mobile and pesa means money in Swahili). Now, one out of every two people in the world who sends money over a mobile phone is a Kenyan. Mobile money is the rare case in which an African country is the global market leader and an exporter of innovation." The author says, "It has been so successful in these markets because it leapfrogged the payment card industry," he said, "which requires expensive ATM and Point of Sale (POS) networks to function. ATMs and POS Terminals require regular maintenance and, with ATMs, regular liquidity balancing. By leveraging third party retail outlets and making the phone the primary means of exchange, mobile money bypassed the need to distribute ATMs and POS Terminals. The reverse is true in the US: mobile money isn't leapfrogging the payment card industry, it's augmenting it."

After the departure of the last Acting Comptroller of the Currency, who was looking to aggressively coordinate regulators and crypto companies, US regulators appear to be at odds with crypto and distributed ledger approaches. In Russia, on the other hand, Sber is purportedly working with Russia's central bank to register its digital assets platform, "which would pave the way for the launch of the digital assets trading platform in Russia." If the US appears hostile to crypto and Russia appears accommodating, Russia may be in a much stronger position as a world financial player if crypto continues to emerge.
