The cause and effects of water pollution by waste settlement seems to be one of the major sources and the causes water pollution that provides the most obvious impact, especially in urban communities in Indonesia.
Residential waste (household), which became one of the causes water pollution due by human activity itself. And in the end of this water pollution has an impact and adverse consequences for humans as well.
Water pollution is a change of state water reservoirs, which reduce water quality so water can not be used again its designation. These changes are due by human activity.
Waste Settlement. One of the causes water pollution is human activity which then creates waste (garbage) residential or household waste .
Residential Waste containing domestic waste in the form of organic waste and inorganic waste and detergents. Organic waste is waste that can be described or decomposed by bacteria, such as the remaining vegetables, fruits, and leaves. While inorganic waste such as paper, plastic, glass or glass, fabrics, woods, metals, rubber, and leather. Inorganic waste can not be broken down by bacteria (non biodegrable).
In addition to organic and inorganic waste, residential waste detergent is the most potentially polluting the water. And now, almost every household detergents.
The impact water pollution caused by waste settlement brings results or outcome of which :

- Decreasing
number of
oxygen
dissolved
in the
water because
most of the
oxygen
used
by
bacteria
to
make
the process of
waste
decomposition.
- Inorganic
waste
into
the river,
could
result in
prevents
sunlight
that is preventing
the process of
photosynthesis
from
aquatic plants
and
algae,
which
produce
oxygen.
- Detergents
very
difficult
broken down by bacteria
so that it will
remain
active
for
long periods
in
water,
polluted
water
and poisoned the
various
aquatic organisms.
- The use of
detergents
on a large
scale
also
increase
phosphate
compound
on
the river
or
lake
water, which stimulates
the growth of
algae
and
water hyacinth
(Eichhornia
crassipes).
- The growth of
algae
and
water hyacinth
which
causes
uncontrolled
surface
water in the lake
or
river
is closed
thereby blocking
the entry of
sunlight
and
resulted in
inhibition of
the process of photosynthesis.
- Water
plants
(water hyacinth
and
algae),
which
brings
death
due to
decomposition
of this
plant
will
spend the
supply
of oxygen.
- Materials
decomposition
aquatic plants
will
precipitate
and
cause
silting.

In addition to the waste caused by residential (household) sources or causes of water pollution is also caused by Agricultural waste, Industrial waste, and in certain places due to Mining waste.

Waste Handling Settlements. Need awareness of all levels of society to act wisely with the household waste it generates.
Waste management, changing lifestyle and mindset of garbage, doing the 3R (Reduce Reuse and Recycle), and not throw garbage, especially in rivers and water reservoirs such as rivers and lakes. Needs to be done by all parties to reduce the impact of water pollution caused by household waste (residential).
And all this can only be realized with a little action as the first, and start from yourself!!
