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

DRIVER-FUNDING-INFRASTRUCTURE FUNDING INFRASTRUCTURE: The nationwide need for investment in water and wastewater infrastructure continues to far outpace the amount of funding that is available at all levels of government and the United States has an estimated need between $400 and $600 billion over the next 20 years for safe drinking water and wastewater treatment infrastructure. One of the primary sources of federal funding for drinking water and wastewater infrastructure are the highly successful, but chronically underfunded, Safe Drinking Water and Clean Water State Revolving Loan Fund (SRF) programs. Modernizing and replacing aging water infrastructure may be the single largest public works endeavor in our nation's history. The U.S. Environmental Protection Agency's Clean Water and Drinking Water Infrastructure Gap Analysis found a $540 billion gap between current spending and projected needs for water and wastewater infrastructure (combined) over 20 years. Other public studies conducted by the Government Accountability Office (GAO) and the Congressional Budget Office (CBO), and a private study produced by AGC partner, the Water Infrastructure Network, have similarly estimated the nation?s water infrastructure needs to range between $400 and $600 billion over a 20-year period.

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.

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.

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

"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-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.

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.

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.

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.

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-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-POLITICS-POLLUTION The original 1948 statute (Ch. 758; P.L. 845), the Water Pollution Control Act, authorized the Surgeon General of the Public Health Service, in cooperation with other Federal, state and local entities, to prepare comprehensive programs for eliminating or reducing the pollution of interstate waters and tributaries and improving the sanitary condition of surface and underground waters. During the development of such plans, due regard was to be given to improvements necessary to conserve waters for public water supplies, propagation of fish and aquatic life, recreational purposes, and agricultural and industrial uses. The original statute also authorized the Federal Works Administrator to assist states, municipalities, and interstate agencies in constructing treatment plants to prevent discharges of inadequately treated sewage and other wastes into interstate waters or tributaries.

"The directive sets essential quality standards at the EU level. One requirement of the directive is that a total of 48 microbiological, chemical and indicator parameters must be regularly monitored and tested. When transposing the Drinking Water Directive into national law, EU member states can set higher but not lower standards. The limits of the microbiological, chemical and indicator parameters are specified in the annexes to the Drinking Water Directive. For water meters, this means that the measurement accuracy must be maintained for all types of water that comply with the parameter limits specified in this document. This can pose a real challenge in terms of the measurement accuracy and particularly the measurement stability of water meters for some of the parameters"

DRIVER-FLINT-TREATMENT-WATER-POLLUTION-CHEMISTRY Former EPA Drinking Water Standards Director, Dr. Joseph Cotruvo developed the US Environmental Protection Agency's (EPA's) first THM Rule in 1979. I spoke with him for his perspective on TTHM in Flint's drinking water: "Scientists have studied the health effects of disinfection byproducts extensively. For example, the January 4, 2006 Federal Register,2 which announced the Stage 2 Rule, cites over 60 mixed result research studies probing the potential health effects of exposure to disinfection byproducts such as TTHM. After reviewing many studies, the Agency concluded that 'no dose response relationship or causal link has been established between exposure to chlorinated drinking water or disinfection byproducts and adverse developmental or reproductive effects.' Nevertheless, EPA takes a very precautious stand, saying the studies 'do provide an indication of a potential health concern that warrants incremental regulatory action beyond Stage 1 DBPR [Disinfectants and Disinfection Byproducts Rule].'"

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-SCARCITY-POLLUTION-INFRASTRUCTURE Four billion people - almost two-thirds of the world's population - experience severe water scarcity for at least one month each year. Over two billion people live in countries where the water supply is inadequate. Half of the world's population could be living in areas facing water scarcity by as early as 2025. Some 700 million people could be displaced by intense water scarcity by 2030. By 2040, roughly 1 in 4 children worldwide will be living in areas of extremely high water stress.

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.

DRIVER-POLITICS Over the past two decades, global studies on the water have reported ongoing issues. In 2008, the United Nations Millennium Development Goals Report said that while there is greater access to drinking water, there are still about 1 billion people without access to safe water and more than 2.5 billion people without good sanitation. The Charting Our Water Future Report by a consortium of business partners in 2009 said that water demand will exceed supply by 50 percent in 2030.
