Curiosities
You can prevent water pollution by following some simple guidelines in your everyday life:

- Do not overuse pesticides and
fertilizers;

- Do not throw litter into rivers, lakes
or oceans;

- Be careful about what you throw
down your sink or toilet.


To prevent water pollution, we must concentrate our attention on four distinct areas:

- Septic Tanks;

- Ozone waste water treatment;

- Industrial water treatment;

- Denitrification;

- Sewage plants.


1) According to a 2012 study from UNICEF, 2,200 children die every day as a result of dirty drinking water.
2) Pollution is one of the biggest global killers, affecting over 100 million people. That’s comparable to global diseases like malaria and HIV.
In 2014 the blue flag was awarded (in Portugal) to 298 beaches and 17 marinas
