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

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 article focuses on rising sea levels, specifically on the east of coast of the US. WIth higher sea levels comes increased flooding and subsequent damage. The article mentions changes in the Gulf Stream, and how those changes affect the East Coast. Ultimately, people that live in these areas need to be prepared as the frequency of severe weather events, especially flooding, increases. This will effect port operations as people are relied upon to monitor and operate the ports. Can the displacement of people be compensated through increased automation?

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).

DRIVER-PUBLICNOTICE-TTHM-TREATMENT When a PWS exceeds the maximum contaminant level (MCL) for both Total Trihalomethanes (TTHM) and Haloacetic Acids (HAA5) it must issue a public notice to inform the consumers of its water that the levels of Total Trihalomethanes and Haloacetic Acids detected in their water have exceeded the MCLs set by Federal Regulations. You can use this template as a guide to prepare that public notice

Article takes a look a worldwide effects of rising sea levels. There seems to be a more drastic effect likely in areas in Northern Sea areas, but all ports to be affected, and since 80% of commerice is shipped, the areas serviced by the ports will be affected.

"For, above all, it is the chasm between the rich and poor in our societies and on a global level that Covid-19 has unlocked. The fatal flaw of the Enlightenment - the unfulfilled promise of economic, social and political equality - has opened up beneath our feet. We are not so much as being thrown back into a bygone primitive age, as being thrown forward into a primitivism that is the true essence of twenty-first century capitalism."

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.

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 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"

"Improving the microbial quality of agricultural water through filtration can benefit small farms globally. The incorporation of zero-valent iron (ZVI) into sand filters (ZVI-sand) has been effective in reducing E. coli, Listeria spp., and viruses from agricultural water. This study evaluated ZVI-sand filtration in reducing E. coli levels based on influent water type and the percentage of ZVI in sand filters"

DRIVER-TTHMs-POLLUTION-PURITY-INFRASTRUCTURE-TREATMENT Trihalomethanes (THMs) are the result of a reaction between the chlorine used for disinfecting tap water and natural organic matter in the water. At elevated levels, THMs have been associated with negative health effects such as cancer and adverse reproductive outcomes. Now a study by government and academic researchers adds to previous evidence that dermal absorption and inhalation of THMs associated with everyday tap water use can result in significantly higher blood THM concentrations than simply drinking the water does [EHP 113:863-870]. The results of this exposure assessment study could serve as a guide for future epidemiologic investigations exploring the potential connection between THMs in tap water and adverse health effects.

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-POLITICS-INFRASTRUCTURE-TREATEMENT Criminal Charges Filed Against 6 Officials Schuette announced criminal charges against six more current and former state employees, bringing the total number of people charged to nine. Liane Shekter-Smith is the former director of the drinking water and municipal assistance office within the MDEQ. She and two subordinates, Adam Rosenthal and Patrick Cook, allegedly misled officials about Flint's water treatment plant, which was not in compliance with lead and copper rules. The other three people charged are current or former employees of the Michigan Department of Health and Human Services. The director of the child health unit, Nancy Peeler, her subordinate, Robert Scott, and a state epidemiologist Corinne Miller allegedly failed to release a report that showed unsafe lead levels in the blood of Flint children. All six are charged with misconduct in office, conspiracy, and willful neglect of duty. Rosenthal is also charged with tampering with evidence, for allegedly requesting water tests that did not show elevated lead.

Most of what we hear about greenhouse gases is associated with carbon dioxide. This research focused on removal of methane, which would have a higher payback if a deployable solution can be identified. "...removing about three years-worth of human-caused emissions of the potent greenhouse gas would reduce global surface temperatures by approximately 0.21 degrees Celsius while reducing ozone levels enough to prevent roughly 50,000 premature deaths annually." The case for funding this technology is strong - "Removing methane from the atmosphere could reduce temperatures even faster than carbon dioxide removal alone because methane is 81 times more potent in terms of warming the climate over the first 20 years after its release, and about 27 times more potent over a century. Methane removal also improves air quality by decreasing the concentration of tropospheric ozone, exposure to which causes an estimated one million premature deaths annually worldwide due to respiratory illnesses."

Cross-collaboration amidst governments and departments are key to promote innovation "These matrices generally corresponded to a few categories: collaboration between governments, collaboration between governments and businesses, and collaboration between governments and citizens. Through these types of innovative efforts, governments at all levels are recognising the significant transformative potential of building matrixed governments that respect, recognise and enable different ecosystems to collaborate in order to make key contributions to society."

"It's entirely possible that this carnival barker of a CEO will continue finding crafty ways to extract tax breaks and favorable contracts from government entities for the rest of his career. But we should be alive to the ways in which Musk's reputation is built on a faulty foundation of borrowed money and worker exploitation. To Musk, the government is only useful in helping to enrich him, and he otherwise expects it to stay the hell out of his way. The problem is that he is now powerful and rich enough to get his wish. For all his supposed brilliance in developing electric vehicles and rockets, this may be his greatest talent: grifting the government. In doing so, he's creating a roadmap for reform, if politicians care to notice." Now he is reached a new level of rich. What if he gets sideways with the government. What if he picks up his toys and moves to Russia? Mars? This a great example of things to come...
