Rio Olympics 2016: 5 problems that have plagued this year's Olympic Games

4) Toxic water at games venues

There have been many issues regarding water pollution in Rio

In a very dangerous development, water bodies where the outdoor water sports like sailing, rowing, kayaking etc were supposed to take place was found to be severely polluted, leading many to question the ability of the organisers to ensure the safety of athletes.

Startling reports emerged of raw sewage and trash from the city flowing into the water bodies which are supposed to host Olympic events. A study found that Rio’s waters had viruses that were up to 1.7 million times more hazardous than an average beach in the US.

The toxic waters were not the only issue troubling those in charge of conducting the water sports. The main ramp at the sailing venue collapsed only days before the opening ceremony, highlighting the poor quality of construction undertaken.
