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

"A lack of face-to-face doctor visits in the UK since the start of the CCP virus pandemic may result in 10,000 unnecessary deaths due to cancer, according to a report from University College London published this week."

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

"What sounds like sci-fi is now becoming a reality, and as these minute cameras pass through your body, they take two pictures per second checking for signs of cancer and other conditions like Crohn's disease." This new technology is a less invasive and more convenient alternative to current practices. The ease of this care provides a more comfortable experience for those who would have needed a traditional endoscopy.

I've swallowed the pill camera before to check an issue in my gut. It was 14 hours of video!!!

usted iron pipes can react with residual disinfectants in drinking water distribution systems to produce carcinogenic hexavalent chromium in drinking water, reports a study by engineers at UC Riverside. Chromium is a metal that occurs naturally in the soil and groundwater.

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.

They are undifferentiated cells capable of being anything. You might know them as stem cells and now a robot can take them up your nose into your brain. "Researchers have developed a stem cell-based microrobot called "cellbot" capable of delivering stem cells to the brain via intranasal passage using a minimally invasive method. The cellbot has the potential to become a key player in the treatment of neurological disorders such as brain cancer, Parkinson's disease and Alzheimer's disease."

"An interdisciplinary approach is needed to find new solutions to a problem that costs the US economy $276 billion per year. What's already happening in one industry could be the solution to another's problem. A great example of this is the use of NASA's analytical methods to examine bacteria in spacecraft in a breast cancer study looking at the links between the disease and bacteria."

Corrosion is a huge cost to the environment. These range from structural failures resulting in environmental contamination, to harmful pollutants being released from iron corrosion, to the over-utilization of natural resources when repairing and replacing damaged metals (Hanson, 2011).(....)the longevity of the metal assets in question across key industries such as O&G, aerospace and architecture is one of the largest drivers for innovation in the coatings industry.

"Lead leached from old pipes after the city began using the Flint River in 2014 without adding corrosion-control chemicals. Flint returned in 2015 to Detroit's water system.(...)Residents in Flint whose homes still may need new water lines due to lead contamination may have a new benefactor in Elon Musk. The tech billionaire caused a stir on Twitter Wednesday, tweeting Wednesday that he was committing to "fund fixing the water in any house" with contamination above federal levels."
