The Department of Defense's (DOD) Office of Corrosion Policy and Oversight (Corrosion Office) provides information, including the needed funding levels for the military departments' Corrosion Control and Prevention Executives (Corrosion Executives), in its Corrosion Office Annual Reports to Congress. Corrosion Executives are responsible for overseeing efforts to prevent and mitigate corrosion of weapon system programs and infrastructure.

"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."

"Sealers, overlays, noncorroding rebars, anticorrosion admixtures, or cathodic protection systems can prevent corrosion"

"Corrosion is a dynamic process, more so than even most corrosion engineers realize. It typically has a number of influencing factors that can vary with time and process variables, and so cause corrosion events or upsets to occur. The reason for the lack of appreciation of this situation is that historically long time intervals associated with inspections and off-line measurements do not afford the opportunity to correlate corrosion excursions with operating and process parameters This paper illustrates the importance of implementing an appropriate and correspondingly dynamic means of corrosion appraisal to help manage industrial processes and related corrosion prevention treatments, and to minimize corrosion upsets and failures, and maximize the availability of the plant assets. Value statements are provided that show the potential savings associated with online, real-time corrosion 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

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-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.

We have all heard of citronella, commonly known to be a natural mosquito repellant. "Biopesticides are substances or mixtures of biological substances used to prevent, destroy, kill, control, or mitigate pests." This article is short but provides a valuable list of biopesticide plants that can be used as the basis for research.

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."

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.

"Through the framework of Collaborative Innovation Groups (CIGs), the Ocean Power Innovation Network (OPIN) offers support to SMEs to collaborate with other organisations, to solve problems which are barriers to the deployment of ocean energy. CIGs focus on challenges which cannot or have not been solved by one SME alone. The OPIN Team have supported a Collaborative Innovation Group (CIG) focussing on creating awareness on the impact of corrosion on offshore renewable projects and how corrosion monitoring can improve corrosion management."

"Arcadia program will work with nature to develop "probiotics" for military materials and equipment to prevent corrosion, decrease drag.(...) Bacteria are the most abundant and diverse lifeform on Earth, coating almost every surface, with the majority spending their lives in biofilms.his lifestyle is universally perceived as problematic since biofilms contribute significantly to equipment degradation. However, biofilms do not have to be a problem. New insights suggest biofilms could be rendered beneficial by redirecting their composition and structure. Similar to the Arcadian vision of harmony with nature, the DARPA Arcadia program will develop "probiotics" to protect military materials and equipment using naturally occurring microorganisms to generate robust and beneficial coatings."
