There are lots of man-made chemicals in drinking water!
CNN: Public Water Supply is unsafe for millions of Americans
Millions of American may be drinking water with unsafe levels of
industrial chemicals.
These chemicals, known as polyfluoroalkyl and perfluoroalkyl
substances or PFASs, have been linked to high cholesterol, obesity,
hormone suppression -- and even cancer.
Persistent Chemicals
-
Although PFASs are very versatile organic compounds that are used
for making packaging materials, these chemicals can be hazardous to
humans. Due to the ubiquity of PFASs, they are found everywhere in
our environment and they eventually permeate through our drinking
water. If these chemicals accumulate in the human body, they may
alter the cholesterol levels and timing of puberty. However, current
studies have not shown all the physical effects that PFASs have on
humans.
Public Water Supply
-
The EPA conducts stringent regulations and quality checks on
drinking water in America every year. The EPA discovered that over 6
million people have been exposed to drinking water that have
chemicals such as perfluorooctanesulfonic acid and perfluorooctanoic
acid. Moreover, the study showed that 16.5 million Americans have
one of six types of PFASs in their drinking water at or above the
maximum EPA limit.

Further studies from Harvard T.H. Chan School of Public health
expose greater concern for the use of these chemicals as they may
affect children’s immune system. In the research conducted by Dr.
Philippe Grand jean, he realized that PFASs could decrease the level
of antibodies against diphtheria and tetanus in young teenagers. In
addition, these chemicals disrupt the immune health for children
which reduces the effectiveness of vaccines
-
Extensive studies on environmental chemicals prove that they can
lower the risk of humans being exposed to them. For example,
perfluorooctanoic acid has been studied rigorously and meticulously
by researchers who have discovered the detrimental effects. As a
result, the EPA has imposed regulations to prohibit the production
of these chemicals.
