How
did your day begin? After rolling out of bed, perhaps you went to
the bathroom, took a shower, brushed your teeth, and got dressed
for school. In the kitchen, there may have been a pot of coffee
brewing and someone at the sink rinsing dishes. Maybe you were asked
you to gather your dirty clothes for the washing machine. As you
left home, somewhere on the block there may have been a sprinkler
watering grass.
Now,
imagine starting your day over again without water.
You
couldn't shower or brush your teeth. Very quickly you would be faced
with the problem of a toilet that didn't work. What would you drink
and eat for breakfast? You couldn't drink orange juice, because
oranges grow on trees that need water. You couldn't drink milk.
Cows feed on grass that needs water, and cows need water to drink
too. At least you wouldn't have to gather your dirty clothes for
the washing machine. There would be no water to wash them! In fact,
if there was no water, you may not have made it to school. Cars
and buses use water to keep their engines cool.
How
many other ways would your life be affected?
Do
you know where the water you drink and use comes from?
If
you live in the Piedmont region of the Altamaha
River watershed (see map), your water comes from surface
water. If you live in the Coastal region (see map), your source
of water is groundwater.
Different
sources of water have different costs and benefits. Groundwater
needs to be pumped to the surface, however this water is relatively
clean. Surface
water requires a lot of treatment to clean it, but the
water is easy to reach. For many people, local geology
often determines whether their water comes from groundwater or from
surface water.
Local rivers provide the main source of drinkable water in the Piedmont
region. It is difficult to obtain groundwater here because of the
region's geology. The landscape is hilly, and the thick clay soil
does not absorb much water. Most rainwater flows downhill into streams
and rivers.
Surface
water needs to be treated in order for it to be safe to drink and
use. Water treatment facilities are special types of industrial
plants that filter and clean water. Several are located along the
rivers of the Altamaha River watershed. At each facility, river
water is withdrawn and cleaned. The facilities provide clean water
to the local cities and towns.
In
the Coastal region, most clean water is supplied by groundwater.
Most rain that falls here seeps into the ground. The landscape is
flat. The porous, sandy soil allows water to trickle deep into the
ground.
The
Floridan aquifer (see map) is the main source of drinkable water
in this region. Deep wells are drilled to the depth of the aquifer,
and water is pumped to the surface. Groundwater is pretty clean.
The only cleaning treatment the water receives, usually, is the
addition of chlorine.
In
both the Piedmont and Coastal regions there are a small number of
people who get drinkable water from wells on their property.
