INTRODUCTION
Total solids is a measure of the suspended and dissolved solids in water.
Suspended solids are those that can be retained on a water filter and are capable of
settling out of the water column onto the stream bottom when stream velocities are
low. They include silt, clay, plankton, organic wastes, and inorganic precipitates such
as those from acid mine drainage. Dissolved solids are those that pass through a
water filter. They include some organic materials, as well as salts, inorganic nutrients,
and toxins.
The concentration of dissolved solids in stream water is important because it
determines the flow of water in and out of the cells of aquatic organisms. Also, some
dissolved inorganic elements such as nitrogen, phosphorus, and sulfur are nutrients
essential for life. ow concentrations of total solids can result in limited growth of
aquatic organisms due to nutrient deficiencies. !levated levels of total solids,however, can lead to eutrophication of the stream or increased turbidity. "oth
eutrophication and increased turbidity result in a decrease in stream water quality.
!levated concentrations of total solids may indicate the presence of
agricultural activities, dredging, or mining upstream from your sample site.
OBJECTIVETo determine the total solids in the given water sample.
PROCEDURES
1. The water sample was shaken thoroughly to homogenise it.
2. # ml of sample was pipetted into the weighed porcelain crucibles or evaporating
dish, which has been cleaned and dried to a constant weight in an oven previously.
3. The water was evaporated off on a steam bath until dry and then it was dried in an
oven at $%# ℃ for one hour.
4. The porcelain crucibles or evaporating dish was cooled in a dessicator before it
was weighing. The drying was repeated until constant weight is obtained.

CONCLUSIONS
&rom the conclusion, we can conclude that the water sample from water
sample ' are not acceptable because it has bigger values from the another sample
which is sample $ and (. The value obtained for sample ' was ' is '(''.( ppm. So
that the value for sample $ and ( can be acceptable.
PRECAUTION
samples may need to be dried for a longer period of time, cooled under proper
desiccation and weighed rapidly in order to achieve a reasonable constant weight.
)e should be aware prolonged drying may result in loss of constituents, particularly
nitrates and chlorides.
