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].'"

"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-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.

NPR discussion on behavioral economist's, Sendhil Mullainathan, book - Scarcity: Why Having Too Little Means So Much, co-authored with Princeton psychologist Eldar Shafir. " Poverty, they find, is like a parasite, consuming mental energy that could be put to more beneficial use. "Put simply, being poor is like having just pulled an all-nighter," Mullainathan once told NPR. And that, he says, hurts their ability to escape poverty. As Washington debates sending checks to Americans and increasing the minimum wage, a new study offers evidence for how such policies could help eliminate poverty. Obviously, giving more money to people without much money helps them with money problems. But the study adds to a growing body of research that says that money really does help workers earn more money."

DRIVERS-SCARCITY-INFRASTRUCTURE This study estimates the likelihood of water shortages over the remainder of the 21st century in 204 watersheds covering the contiguous United States. The estimates are based on monthly projections of water demand and renewable water supply in light of population growth and climate change, taking into account water storage and transbasin diversion capacities. The study then examines several possible adaptations to projected shortages, including water withdrawal efficiency improvements, reservoir storage enhancements, demand reductions, instream flow reductions, and groundwater depletion. Results provide a broad measure of the relative efficacy of the adaptation measures and show when and where the measures are likely to be helpful.

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.

"The antiviral remdesivir treatment reduced the risk of hospitalization among COVID-19 patients when administered soon after they were diagnosed, according to a new study from Gilead Sciences, which developed remdesivir."

"The global energy management system market was valued at USD 8.2 billion in 2020 and expected to reach USD 19.91 billion by 2026 and grow at a CAGR of 16.2% over the forecast period (2021 - 2026). The increasing focus toward issues, such as managing energy consumption, optimizing the use for renewable energy sources, and reducing carbon footprint and greenhouse gas emissions, is creating a demand for EMS. Further, cloud services effectively minimize operational costs of software development and maintenance and direct the monetary costs, cost of time, and spent resources on maintaining the in-house IT professionals and infrastructure on gathering, storing, and analyzing energy data.​ Cloud services are an ongoing trend responsible for the growth of the market studied."

A new survey-based study explains how automation is reshaping the workplace in unexpected ways. Robots can improve efficiency and quality, reduce costs, and even help create more jobs for their human counterparts. But more robots can also reduce the need for managers. What if more robots = a better quality of life. We always seem to go negative. What if we could work less, not more?

It is often implied that the young are more concerned about the environment than older adults, but this study suggests that is not the case. "Older people are just as likely as younger people to recognize the need for action on climate change and to say they're willing to make big sacrifices to protect the environment, suggesting claims of a generational divide over the future of the planet may be exaggerated." The polling included Baby Boomers, Gen X, Millennials, and Gen Z, with the results reflecting very similar beliefs about the significance of the issues and the need for action. If politicians knew this, would they behave differently, and take bolder steps to mitigate climate change?

Super interesting, great find!

"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"

The USDA released a study highlighting barriers that SNAP participants face when trying to eat a healthy diet. Nearly 90% percent identified barriers, with 66% stating that healthy food is not affordable. Additionally, SNAP participants' responses around preparing and storing food were identified as barriers related to food insecurity.

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 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.

It reversed age-related inflammation in the body and the brains of older mice, and changed the chemistry of their brain's hippocampus - the region involved in learning and memory - to resemble that of younger mice. The transplant also led to improvements in the older mice's memory, learning and anxiety levels, all of which are affected negatively with age.

A new set of case studies and best practice examples to help cities reduce emissions has been launched by the World Economic Forum and Accenture.

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.

Princeton researchers have developed a new way to make fuel from cellulose-Earth's most abundant organic compound, found in all plant cells-speeding up a notoriously slow chemical process and in some cases doubling energy yields over comparable methods. Cellulosic biomass has long been seen as a key ingredient in curbing greenhouse gas emissions, providing the feedstock for a renewable and clean-burning transportation fuel. The U.S. Department of Energy has conducted a series of studies showing that at least one billion tons of biomass could be sustainably harvested each year in the United States without disrupting forests or food production to produce biofuels, largely from cellulose.

When the National Election Study began asking about trust in government in 1958, about three-quarters of Americans trusted the federal government to do the right thing almost always or most of the time. Public trust reached a three-decade high shortly after the 9/11 terrorist attacks, but declined quickly thereafter. Since 2007, the share saying they can trust the government always or most of the time has not surpassed 30%. Currently, 36% of Democrats and Democratic-leaning independents say they can trust government, compared with 9% of Republicans and Republican-leaners. Throughout Trump's tenure, more Republicans than Democrats reported trusting the government, though that has flipped since Biden's election.
