HOW DOES THE

THE REST OF THE WORLD?
50
In the United States, nearly 13 billion gallons of freshwater are extracted every hour.
The water is pumped into treatment plants, decontaminated, and distributed to the
masses. On average, each American is responsible for 125 gallons of freshwater usage
each day. Food production accounts for the majority of this usage.
SOURCES OF
FRESHWATER
Approximately 70% of the Earth is covered in water, but only 2.5%
of it is usable freshwater. Here’s the kicker: only 1% of the
freshwater on Earth is able to be extracted for treatment. The rest
is frozen inside of glaciers and snowfields. Surface water and
groundwater are the primary sources for freshwater extraction.
WHAT IS SURFACE WATER?
Surface water originates from rivers, lakes,
swamps, and marshes. It accounts for 75% of the
total freshwater used in the United States. Surface
water is pumped to a water treatment plant where
it is treated and distributed to municipalities. The
Great Lakes alone provide 84% of North America’s
freshwater supply. As the population continues to
grow, there is an urgent need to ensure that
freshwater sources remain clean and sustainable.
Groundwater lives below the Earth’s surface. It accounts for 25% of the freshwater used in the
United States. This water seeps through soil and fractures in rock formations, ultimately pooling
in naturally occurring underground reservoirs known as aquifers. Groundwater is extracted from
aquifers and pumped to water treatment plants. It is then treated and distributed to the masses.
The Ogallala Aquifer is the largest groundwater system in North America. It contains enough
water to cover all 50 states in 18 inches of water.
A COMPREHENSIVE OVERVIEW OF
FRESHWATER USAGE IN THE UNITED STATES
Each day, Americans use significantly more freshwater per capita than people in other similarly
developed nations. For example, the average American uses 4x more freshwater every day than
the average German. While a portion of this discrepancy is owed to the widespread geography of
the United States, that alone doesn’t account for the difference. Canada, another sprawling
nation, manages to use 40% less freshwater per capita on a daily basis. There is a pressing need
to reduce the collective water footprint in the United States for long-term sustainability.

Freshwater is used in a variety of ways. Obviously, we need to drink it to stay alive.
But there are many other uses. Freshwater is used to manufacture consumer
goods, plastic, and food. It is also used to power the world around us. Agricultural
irrigation alone uses 38% of all freshwater. Thermoelectric-power generation also
accounts for 38% of freshwater use, but it is typically returned to the water
supply—making it far more sustainable.
