We all know that water is essential to our health. It’s recommended that we drink eight glasses of water a day to stay hydrated. But what if that water was contaminated with sewage? A new study has found that up to 10 percent of the world’s water supply is contaminated with feces.
In the study, published in the journal Science Advances, an international team of researchers analyzed data from over 2,000 sites in 192 countries. They found that 2 billion people around the world are drinking water that contains fecal matter.
Fecal contamination can come from a variety of sources, including sewage, animal waste, and agricultural runoff. The study found that the vast majority of the contaminated water sites were in developing countries.
The researchers say that the findings highlight the need for improved sanitation and water treatment in many parts of the world. They also point to the need for better monitoring of water quality.
So, next time you take a sip of water, think about where it came from and what might be in it. You might just decide to stick to bottled water instead.
