DRIVER-INFRASTRUCTURE-FUNDING-POLITICS 5-year update to 50-year Texas Water Plan QUICK FACTS: **Texas' state water plans are based on future conditions in the event of a recurrence of the worst recorded drought in Texas' history-known as the "drought of record"-a time when, generally, water supplies are lowest and water demands are highest. **Texas' population is anticipated to increase 73 percent between 2020 and 2070, from 29.7 million to 51.5 million, with approximately half of this growth occurring in Regions C and H. Water demands are projected to increase less significantly, by approximately 9 percent between 2020 and 2070, from 17.7 million to 19.2 million acre-feet per year. **Texas' existing water supplies-those that can already be relied on in the event of drought-are projected to decline by approximately 18 percent between 2020 and 2070, from 16.8 million to 13.8 million acre-feet per year primarily due to reservoir sedimentation and depletion of aquifers. **Water user groups face a potential water shortage of 3.1 million acre-feet per year in 2020 and 6.9 million acrefeet per year in 2070 in drought of record conditions. **Approximately 5,800 water management strategies recommended in this plan would provide 1.7 million acrefeet per year in additional water supplies to water user groups in 2020 and 7.7 million acre-feet per year in 2070. **Conservation strategies represent approximately 29 percent, or 2.2 million acre-feet per year, of all recommended water management strategy volumes in 2070 and were recommended for more than half of the water user groups in the plan. **The estimated capital cost to design, construct, and implement the more than 2,400 recommended water management strategy projects by 2070 is $80 billion. If strategies are not implemented, approximately one-quarter of Texas' population in 2070 would have less than half the municipal water supplies they will require during a drought of record. **If Texas does not implement the sta

Here are 12 critical facts about TTHM as the city's fight to reduce it continues: 1. Trihalomethanes are actually a group of four chemicals that are formed along with other disinfection byproducts when chlorine reacts with organic materials such as leaves or dirt in water, according to the U.S. Environmental Protection Agency. 2. TTHMs are odorless and colorless, according to the Michigan Department of Environmental Quality. That means the high levels of TTHM in Flint water last year are not related to problems such as discoloration and odor in tap water. 3. The four trihalomethane chemicals are chloroform, bromodichloromethane, dibromochloromethane and bromoform. 4. U.S. EPA regulates TTHM at a maximum allowable, annual, average level of 80 parts per billion. The standard has been in place since December 2001 for large public surface water systems and since December 2003 for small surface water and all groundwater systems. 5. Four of eight testing sites in Flint averaged more than the acceptable limit of 80 parts per billion of TTHM last year. 6. Testing for TTHM is done on a quarterly basis, which means that people who use the system are exposed to water for several months before public notice is required. That's because TTHM is a chronic -- not immediate --health threat, according to the DEQ. 7. U.S. EPA estimates the 80 parts per billion standard prevents an estimated 280 cases of bladder cancer each year out of a total of more than 330 million people who use public water supplies nationwide. 8. Since it started using the Flint River as its water source, three quarterly tests have produced these TTHM results in the city: 15 samples have been above the TTHM threshold. Nine samples have tested at less than 80 parts per billion. 9. The most recent quarterly test showed just one site of eight that was above the 80 parts per billion threshold. And a voluntary test of the same sites in late January by the city were all within were all within the limits. 10. The testin

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.

DRIVERS-TREATMENT-TTHM-POLLUTION-SCARCITY-FUNDING Disinfection by-products (DBP) are a class of chemical by-products also referred to as trihalomethanes (THMs), formed when chlorine or bromine interacts with the natural organic materials found in water. DBPs also include other formed products, such as haloacetic acids, haloacetonitriles, haloketones, and chlorophenols. The composition and levels of specific DBPs are determined by water quality, water treatment conditions, and disinfectant type (IPCS, 2000). Primary sources of DBPs are chlorinated drinking water and recreational water bodies, such as swimming pools. In drinking water, trichloromethane is the predominant DBP, usually found at much higher levels than bromodichloromethane; tribromomethane is the least abundant (Krasner et al., 1989). DBPs are volatile at room temperature and can be detected in ambient air during activities such as showering, bathing, dishwashing, and swimming (Backer, et al., 2000; Gordon et al., 2006). Trichloromethane has industrial applications and is used to produce refrigerants and feedstock. It may be released into the environment where chlorine-based chemicals are used for bleaching and disinfecting processes or disposed at hazardous waste sites (IPCS, 2004; LaRegina, et al. 1986). Tribromomethane has limited industrial uses, mainly in geological assaying, electronics manufacturing, and as a solvent in laboratory analyses (ATSDR, 2005). DBPs tend not to bioaccumulate in aquatic organisms or persist in open or surface waters or soils, but they can remain in water within closed pipe systems. Workplace exposure may occur during the production of trichloromethane or tribromomethane, or in workplaces where DBPs may be generated, such as pulp or paper manufacturing, swimming pools, and water treatment plants (IPCS, 2004).

DRIVERS-POLLUTION-TREATMENT-SCARCITY-INFRASTRUCTURE Total trihalomethanes (TTHM) are a group of disinfection byproducts that form when chlorine compounds that are used to disinfect water react with other naturally occurring chemicals in the water. They are colorless, and will evaporate out of the water into the air. There are four significant TTHM potentially found in disinfected drinking water and their combined concentration is referred to as total TTHM. Levels of TTHM generally increase in the summer months due to the warmer temperatures, but can also be affected by seasonal changes in source water quality or by changing amounts of disinfection added. Water systems often can experience temporary increases in TTHM due to short-term increases in chlorine disinfection. Chlorine disinfection increases can occur when there is a water main break, when water systems are under repair, or when there is a potential microbial (example: bacteria) problem or threat.

"The smart homes market was valued at USD 79.13 billion in 2020, and it is expected to reach USD 313.95 billion by 2026 and register a CAGR of 25.3% over the forecast period (2021 - 2026). Across real estate companies and the architect ecosystem, the 'new normal' defined through the social distancing results in a requirement to go back to the redesign basics and reinvent the residential real estate product by factoring in new-age designing, efficiency, and innovation. As the redesign happens, the need for a totally new set of amenities has resurfaced and gained prominence. What the customer will need in the 'new normal' has undergone a revolution in the crisis triggered by the COVID-19 pandemic, and it is leading to a paradigm shift in residential spaces."

"The global semiconductor shortage will lead to 7.7 million fewer vehicles produced in 2021, costing automakers billions in lost sales, according to consulting firm AlixPartners. The forecast, released Sept. 23, estimates that the shortage will cost the auto industry $210 billion globally in lost revenue in 2021, up sharply from the May projections of $110 billion in forgone sales and 3.9 million fewer vehicles built."

When we modeled what the next two decades would look like if we continued current underinvestment trends, we found that no industry is immune to water disruptions. The most water-reliant businesses will spend $250 billion in 2039 on costs related to water service disruptions. Less reliable water service would make industries less efficient and profitable, and the consequences would ripple across the entire economy, leading to more than $4.5 trillion in lost business sales, a $2.9 trillion decline in the gross domestic product (GDP), and 636,000 fewer jobs. Individual households and communities would also endure the consequences of underinvestment as more frequent and extreme weather inflict shutdowns, and street flooding deteriorating and rupturing water infrastructure. Without proper infrastructure investment, there will be greater costs to US households. At the current rate, costs will be seven times higher in 20 years than they are today, totaling $14 billion in 2039.

"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."

DRIVER-INFRASTRUCTURE-SCARCITY-POLITICS By 2071, nearly half of the 204 freshwater basins in the United States may not be able to meet the monthly water demand. These model projections, recently published in the journal Earth's Future, are just one preliminary component of the upcoming Resources Planning Act (RPA) Assessment expected to be published next year. In 1974, congress required that this assessment of US renewable resources be published every 10 years. Conducted by the U.S. Forest Service, the research describes two causes for the projected shortages. The first is that the U.S. will simply have more people. Despite that the average American is using less water, population growth is still expected to increase water demand across most of the country. Second, the water supply itself is expected to decrease. Projected climate change affects both rain patterns and temperatures. While rainfall is expected to increase in some parts of the US, the southern Great Plains and parts of the South won't be so lucky. The water basins rely on rainfall to feed the rivers and tributaries that flow into them. Separately, more water will evaporate from reservoirs and streams as the climate gets warmer, further chipping away at the water supply. Around 50 years from now, many U.S. regions may see water supplies reduced by a third of their current size, while demand continues to increase.

According to the new report released last week by the American Society of Civil Engineers (ASCE) and Value of Water Campaign, the United States is underinvesting in its drinking water and wastewater systems, putting American households and the economy at risk. The report, "The Economic Benefits of Investing in Water Infrastructure: How a Failure to Act Would Affect the U.S. Economy Recovery," finds that as water infrastructure deteriorates and service disruptions increase, annual costs to American households due to water and wastewater failures will be seven times higher in 20 years than they are today -from $2 billion in 2019 to $14 billion by 2039.

DRIVER-WATER-SCARCITY-INFRASTRUCTURE-MATERIALS The North American drinking water infrastructure network spans an estimated 1 million miles, more than four times longer than the National Highway System, and that doesn't even take wastewater pipes into account. Much of the water infrastructure in the United States will need to be replaced in the next three decades. A large portion of water pipes was installed during three periods, and they will all need to be replaced in the next 25 years. Consider the following The oldest cast iron pipes laid in the late 1800s usually last 120 years; Pipes laid in 1920s must be replaced after 100 years; Pipes from the post-World War II boom wear out after 75 years. According to a 2012 report done by the American Water Works Association, the cost estimate to replace the old pipes is approximately $1 trillion over the next 25 years. The longer our water infrastructure is out of sight and out of mind, the closer we are to a serious national situation that will require immediate and dramatic funding. The cost of water infrastructure replacement far exceeds the financial capabilities of local water utilities and requires a strong commitment from not only utilities but rate-payers and government as well.

"According to the 2019 Women in STEM Decadal Plan, prepared by the Australian Academy of Science (AAS) and the Australian Academy of Technology and Engineering, every organisation in Australia is increasingly reliant on STEM skills to thrive, whether they operate in government, academia, industry, or the education sector. "All these stakeholders face a common challenge: the need to tackle the significant under-representation of women in the STEM workforce, because we can ill afford to under-utilise all of the nation's available talent. To achieve this requires removing barriers to participation at every point of the STEM pipeline. We must create an environment where girls and women can readily engage in STEM education and then use those skills to progress through their careers to senior levels," the AAS report states. In many ways, the corrosion industry reflects this general state of affairs, being reliant on researchers - investigating both the process of corrosion and ways to control it - and practitioners managing its application."

"Banks said CalPERS' massive investments in China were estimated in 2018 to be $3.1 billion in at least 172 Chinese firms. He also noted that Secretary of State Mike Pompeo recently told a meeting of the nation's governors that included Newsom that CalPERS "is invested in companies that supply the People's Liberation Army (PLA) that put our soldiers, sailors, airmen, and Marines at risk.""

"Facebook founder and CEO Mark Zuckerberg-who in the past openly pandered to Chinese officials, likely in an effort to ensure the social media giant's entry into the Chinese market-recently made a speech at Georgetown University in which he criticized the Chinese regime for its internet censorship, striking a remarkably different tone. "

Starlink has set up a wholly-owned subsidiary in India called Starlink Satellite Communications Private, with a a "stretch goal" to deploy 200,000 Starlink user terminals in more than 160,000 rural districts in India by December 2022. Starlink is also in talks with two telecommunications companies in the Philippines, where it also wants to launch its satellite service. This project would result in Internet availability to more people - Starlink wants to introduce its internet to schools in and near to the capital city of New Delhi.

"In Gallup polling throughout the first quarter of 2021, an average of 49% of U.S. adults identified with the Democratic Party or said they are independents who lean toward the Democratic Party. That compares with 40% who identified as Republicans or Republican leaners. The nine-percentage-point Democratic advantage is the largest Gallup has measured since the fourth quarter of 2012." What I found to be more significant was the following: "The 44% of Americans who identify as political independents, whether they subsequently express a party leaning or not, is up from 38% in the fourth quarter of 2020 and is above 40% for the first time since 2019. This is consistent with the historical pattern whereby independent identification typically declines in presidential election years and increases in odd-numbered years. However, the percentages identifying as independent in 2020 and thus far in 2021 have been unusually high compared with prior presidential election and odd-numbered years. Thus, the current level of independent identification ranks among the highest Gallup has measured in any quarter since 1988" More people relate to neither party than to one, so why do they both continue on a trajectory of not satisfying the public? Is the message never heard that the Center is where most of America lives?

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.
