Why can't 90-degree water do brain teasers?

You can't drink boiled water when it reaches 90 degrees Celsius, because the tap water you drink every day is chlorinated. The interaction between chlorine and residual organic matter in water will form toxic carcinogenic compounds such as halogenated hydrocarbons and chloroform. When boiling water is heated to 90℃, the content of halogenated hydrocarbons rises to 19 1 μ g/L, and chloroform rises to 177 μ g/L, both exceeding the national standard by two times. So you can't drink it.
