A new interactive map details where hexavalent chromium, the notorious “Erin Brockovich” carcinogen, contaminates tap water serving 251 million people, exceeding levels scientists say are safe. Researchers at the Environmental Working Group analyzed federal and state water testing data to create the map.
The updated map includes 918 new detections of toxic hexavalent chromium, or chromium-6, in California since the last version of EWG’s map was released, in 2016. Chromium-6 contaminates water in all 50 states, Puerto Rico, the Northern Mariana Islands and Guam.
“Too many people are exposed to chromium-6 in their drinking water,” said Tasha Stoiber, Ph.D., a senior scientist at EWG. “Communities across the country have water with potentially harmful levels of this carcinogen.”
In January, researchers at the University of California, Berkeley, and the University of California, Los Angeles, found that 371,000 Californians are drinking water that may contain high levels of chromium-6, or chemicals like arsenic and nitrate. The researchers found disproportionate harm to communities of color and emphasized that the results of the study likely understated the number of people affected by unsafe drinking water.
“People have a right to clean and affordable drinking water served by community water systems and wells,” Stoiber said. “Despite knowledge of chromium-6 contaminating tap water, the Environmental Protection Agency has done nothing.”
There are no federal rules limiting chromium-6 in drinking water. The EPA has a drinking water standard of 100 parts per billion, or ppb, for total chromium, which includes all forms of chromium, including chromium-6. That standard is based on potential adverse dermatological effects over many years, such as allergic dermatitis and other skin reactions.
In 2007, the National Toxicology Program, a branch of the National Institutes of Health, published finding that long-term exposure to chromium-6 caused cancer in rodents. The EPA in 2008 then began a review of the harmful health effects linked to exposure to chromium-6 in drinking water. That review is ongoing.
“It is inexcusable the government has done so little to protect us from exposure to chromium-6, which has been shown to cause cancer,” said David Andrews, Ph.D., a senior scientist at the EWG.
“In nearly 15 years, the EPA has been unable to publish a completed human health assessment of chromium-6, which further blocks any progress toward a health-protective drinking water standard for this carcinogen. Every American should be outraged by this inaction,” Andrews added.
Government scientists in California and other states say extraordinarily low levels of chromium-6 can cause cancer in people. An analysis by state scientists in California showed that exposure in water suggests chromium-6 may cause stomach cancer.

Quality control and optimization of coating processes in chrome plating
Chrome plating is an electroplating technique to apply a thin layer of chromium onto a metal surface. This layer can have different functions, from increasing surface hardness, over providing corrosion or wear resistance to decorative purposes. For an efficient plating process, chrome plating baths contain catalysts, such as sulfuric acid, MSA, or MDSA. Excessive catalyst concentrations can cause defects on the plating surface, while insufficient concentrations can impair the process and/or cause dull spots or...

4 Health Benefits Of Water Purification With Hydrogen Water Dispenser Machine
We all want to drink clean and safe water. But the problem is that clean water is not available everywhere. Therefore, it is a great idea to use a high-quality water purifier. In case you don't know, groundwater may contain a lot of impurities. The presence of these elements in drinking water is not good for human health. In this article, we are going to discuss common impurities found in groundwater and the health benefits you can enjoy if you make use of a water purifier to get rid of these impurities from your...
THE SELECTION STEPS OF SLURRY PUMP
The reasonable selection of slurry pump is one of the key factors to improve the service life of the pump. The reasonable selection of slurry pump includes reasonable selection of pump series, performance parameters, material of overcurrent parts, sealing type and transmission mode.1. Selection of pump seriesThere are many types of centrifugal slurry pumps. Different series of pumps should be selected according to the nature of the slurry. Taking the Warman pump as an example, L-type pumps can be used for low-abras...

Point Of Use, POU water treatment for potable consumption needs to be the baseline common practice. The choice of treatment system can be of , just that, choice. But the facts and full understanding of these water treatment systems needs to be known. Marketing is fine, it is part of capitalism, but misleading claims need to be dealt with. There is on one "best" POU water treatment system or brand. This is why consumer education is needed. "Superman is not coming" we must save ourselves. Reading Erin Brockovich's book title above, is good to understand certain issues. Other book sources on the options of water treatment exist. Below is a link to the consumer reports. https://www.consumeraffairs.com/homeowners/water-treatment-systems/ . Whole house systems are different than POU systems. Point Of Entry, POE is a term for them vs POU. Every region can have different contaminants and many people have different reactions to contaminants. Infants are prone.
