Toxic chemicals in drinking water in the United States could cause over 100,000 cancer cases, a scary new study suggests.
Researchers at the Environmental Working Group discovered 22 carcinogens in water throughout the country.
Despite the fact that most of the water systems they tested were within the federal limits for each of these poisons, the researchers estimated that their cumulative effects could be severe during the lifetime of Americans.
Exposure to arsenic, disinfectant products and traces of radioactive chemicals such as uranium and radium had the main effects on cancer risks.
Although levels for each fall below federal limits, the collective effects of toxic pollutants in the United States may: s drinking water be responsible for over 100,000 cases of cancer per year (file)
Over 1.7 million new cases of cancer are diagnosed in the United States each year.
Over the same period, over 600,000 people die from the disease.
Better prevention strategies, earlier detection and better treatments – such as the immunotherapies that revolutionize the future of the disease – have driven cancer mortality dramatically.
The elimination of the disease is not somewhere in sight.
This is partly because its roots are many and difficult to control.
Instead of being triggered by something, genetics, what you eat, where you live, how you eat, and of course the water you drink, all play the role of raising or lowering cancer risks.
Some chemicals, like arsenic, are almost impossible to stay out of the water in some places.
For example, in some areas of Illinois, the earth is rich in arsenic, a toxic, carcinogenic heavy metal, linked to liver and bladder cancer.
Arsenic seeps into the groundwater and is wound up in our bodies.
It also leaks into the water supply from many types of manufacturing plants.
The US water system treats drinking water with chlorine – a non-carcinogenic cleaning chemical – in an effort to reduce or eliminate the metal.
The US Environmental Protection Agency (EPA) limits the permitted level of arsenic in drinking water to 0.01 parts per million.
It has similar lid on other poisons like uranium and a lot of disinfectant.
Isolated, on any given day, these levels are safe.
But we do not drink these chemicals individually or in isolated cases.
"Drinking water contains complex mixtures of pollutants, but still the authorities are currently assessing the health risks of tap water pollution one by one," said Sydney Evans, principal author of the newspaper and a science analyst at EWG.
"In the real world, people are exposed to chemical combinations, so it is important that we begin to assess the health effects by looking at the combined effects of multiple pollutants."
EWG used a new model to estimate how much the collective effects of all water pollution would increase cancer risks during a person's lifetime, estimated to be about 70 years.
After their math, these pollutants are responsible for 100,000 or more cases of cancer in the United States.
"The vast majority of Community water systems meet legal standards," said Dr. Olga Naidenko, EWG's vice president of scientific investigations.
"Nevertheless, the latest research shows that pollutants present in the water at these concentrations – quite legally – can still harm human health.
" We must prioritize spring water protection to ensure that these pollutants do not start with drinking water supply . & # 39;
