"The public hearings showed sharp differences of opinion about SpaceX's plans to conduct orbital launches from Boca Chica. Many attendees were strong advocates for the company and the proposed launch site, calling it critical to the nation's future in space. They also played down the environmental impact, often comparing it to the launch sites at Cape Canaveral in Florida, which are embedded within a wildlife refuge." This hit resonates because it hits on lots of areas - environmental, political, technological, geopolitical, demography... There will always be people for and people against. I feels like Space X did a nice job of stacking the room in their favor.

The article discusses emissions at ports around the world and focuses on a measurement of a port's affects on the environment through a measurement called Port Environmental Index (PEI). The PEI consists of standards that will allow the tracking of emissions and effects on the environment for the port over time. The internet of things (IOT) will allow real time monitoring.

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

"Corrosion has a huge economic, environmental and sustainability impact on virtually all facets of constructional materials, from highways, bridges, and buildings to oil and gas, chemical processing, desalination, nuclear, power facilities, water, and wastewater systems. In addition to causing severe environmental damage and threats to public safety, corrosion disrupts operations and requires extensive repair and replacement of failed assets. The annual cost of corrosion worldwide was estimated to exceed $U.S.2.5 trillion in 2016, which translates to 3 to 4% of the Gross Domestic Product (GDP) of industrialized countries according to NACE IMPACT study report. (...) To reduce the huge cost and the environmental impact of corrosion and enhance the sustainability of materials used for construction, available corrosion control practices such as proper material design and selection, the use of corrosion inhibitors, coatings, cathodic protection etc., are recommended and could lead to savings of between 15 and 35% of the cost of corrosion. This translates to between US$375 and $875 billion annually"

An article about emergining issues in ports. This doesn't touch on current problems related to back ups from COVID, but it identifies several other issues such as international considerations, environmental, port scalability, governance and volatility of demand. Interesting in that it touches on so many issues. While so many articles focus on climate change this touches on other areas such as port governance.

"The dirt beneath our feet is getting poorer and on many farms worldwide, there is less and less of it." "This article is part of a new multimedia series Follow the Food by BBC Future and BBC World News. Follow the Food investigates how agriculture is responding to the profound challenges of climate change, environmental degradation and a rapidly growing global population. Our food supply chains are increasingly globalised, with crops grown on one continent to be consumed on another. The challenges to farming also span the world."

"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-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].'"

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-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.

"Canadian utility redirects $2.3B away from expensive 730MW coal to natural gas conversion, Investment will now fund 3.5 GW of affordable wind and solar." This is a positive move towards a "collective conscientiousness for social and environmental factors," by using renewable energy with new construction aimed for completion in 2025 (H1).

"It is estimated that worldwide plant disease caused 13%, insect 14% and weed 13% loss in food production and accounted for 2000 billion dollars economic loss per year" The initial response to this challenge has been the use of chemical pesticides, but those have historically caused environmental and health issues. This article does a nice job of summarizing the current state of nanopesticides, which hold the promise of being equally effective as the chemicals in use now while doing much less collateral damage. The article concludes with a punch list of the challenges that need to be overcome to make these nanopesticides easy to deploy and raise the confidence that they are safe.

The U.S. Environmental Protection Agency on Thursday finalized a rule that will slash the use of a potent climate-warming gas commonly used in refrigerators and air conditioners by 85% over the next 15 years, a move that will help halve greenhouse gas emissions this decade. he EPA and White House also announced on Thursday that the administration will take an interagency approach to prevent the illegal trade, production, use, and sale of HFCs and prepare for enforcement actions to punish violations of the law.

The segments mated briefly on Friday are codenamed B4 (the Super Heavy booster) and Ship 20 (the Starship upper-stage). The pair won't launch until they have a licence from the Federal Aviation Administration (FAA). The government agency is currently conducting an environmental review that will invite at some point a 30-day public consultation. So, the maiden orbital outing is still some way off. But Mr Musk is very keen that it should happen well before the end of the year. He described seeing the brief mating of the segments on Friday as a "dream come true". He has to make Starbase work, everything else is dependent on it. Never good to have all your eggs in one basket.

The Federal Aviation Administration (FAA) is evaluating Space Exploration Technologies Corporation's (SpaceX) Starship/Super Heavy program, in particular a proposal to operate the Starship/Super Heavy launch vehicle at its existing Boca Chica Launch Site in Cameron County, Texas and conduct launches originating from this site. This could be real trouble for Musk. If the FAA makes his life difficult, how will he react?

The third edition of NASA's "International Space Station Benefits for Humanity" book now is available. The new edition fills more than 200 pages with the many benefits of conducting research on the orbiting microgravity laboratory and includes new assessments of the economic value - as well as greater detail about the scientific value - of the International Space Station. Really this is NASA defending it's spending.

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.

The comments hint at Musk's goal, stated multiple times over the years, that he would like to transform the planet's atmosphere to make it more hospitable to human life. It forms part of his overall goal with SpaceX: reduce spaceflight costs, use it to establish permanent human presences elsewhere in space, and transform humanity into a multi-planetary species. I absolutely love that he thinks about changing another planets atmosphere. For get changing the world, change a different planet. Amazing.
