March 22 is a United Nations global anniversary aimed at raising awareness of the value of freshwater. The day aims to encourage action to address the global water crisis and raise awareness of the 2.2 billion people who lack access to safe drinking water.

Recent studies have shown that boiling tap water before drinking can remove nearly 90% of microplastics from the water source. The National Oceanic and Atmospheric Administration (NOAA) defines microplastics as very small plastic particles less than 5 mm in size.
