We use water every day for lots of things. For example, we brush our teeth, wash our dishes, and water our
lawns. Sometimes though, we forget that water is a valuable resource. Only 0.65% of Earth’s total water
supply is neither salty nor frozen and is usable. And the quality of that vital water is at risk, because as it moves
through the water cycle, it is exposed to a host of natural and man-made pollutants. As clouds drift above cities,
and rivers run past factories and fields, their waters pick up industrial and agricultural wastes. As groundwater
infiltrates through the soil, it gathers up mineral compounds and buried toxic chemicals.
This pollution can destroy our ecosystems, water quality, and our water supply. Pollution comes in the form
of pesticides, herbicides, fertilizers, paint, oil, gas, cleaning solvents, and other contaminants. It can seep into
the soil and reach our groundwater supply. Pollutants also enter streams, and oceans via sewer systems, killing
stream and ocean life. Beaches in Hawai‘i have been closed periodically due to pollution washed down from
streams or overflowing sewer systems.
Human activities that modify our ecosystems can inadvertently interfere with the water cycle. For example,
many industries release waste gases into the air, and when it rains, the gases are absorbed in the falling rain
– and may even be recycled again through the water cycle. This polluted rain is called acid rain. An acid is a
chemical that can harm living things. Since water is a universal solvent, many substances are dissolved by rain
only to find their way in surface runoff and groundwater.
By paying attention to how we treat water, and by keeping it clean, we can prevent water pollution. Today,
we finally are seeing people becoming more careful with the water they use. This is referred to as water
conservation and pollution prevention. There are many laws that govern residences and businesses, and the
way they dispose of toxins that may reach our water systems. For example, if your mom or dad has just finished
painting the living room and they need to dump the excess paint, or if your local car mechanic needs to dispose
of used oil, they must dispose of these toxins at a designated pollution collection agency. Homes and businesses
may also be limited by the amount of water they use during droughts.
Even the ancient Hawaiians had formal rules that discouraged water waste. The chiefs were the trustees of
water, and they exercised control over it. For example, they set up water use in the upland areas so that there
would be enough water to be used by lowland communities. They also established strict schedules for clearing
and diverting rivers and streams, so that not one family would have more water than needed. Farmers were
expected to keep their fields free of weeds and clutter to keep communal streams clean.
There are lots of ways we can prevent water pollution and exercise water conservation at home. Our water
supplies must be carefully managed, so that we can continue to provide people and wildlife with clean,
pure water. After all, water is the source of life. We cannot live without it…
