Indicators of Physical
debris
Nuisance
Turbidity and color caused by dissolved and
suspended matter
Waste products are decomposed and consumed by
larger organisms to sustain life
Zone of Active Low DO (dissolved oxygen) or none at all
Decomposition Scum may be floating on surface
Odors from putrefaction of organic matter
Water is darker and grayish in color
Point where water quality gradually returns to its
biological and physical state prior to the entrance of
Zone of Recovery waste discharge
Algae reappears and fungi disappear
Some of the harder fish such as carp will appear

Involves collecting a designated amount of water in a
container at a specific point in the stream
Collected by mixing samples that have been
collected at regular intervals (usually 1 hr) over a 24 hr
period
Composite Sampling
Keep samples at or below 4°C during composite
sampling
Use same criteria as grab sampling
If analysis is not started within 2 hrs of sample
collection, keep the samples at or below 4°C from
Transportation of Samples time of collection
In no case start analysis more than 24 hrs after grab
sample collection

analysis
Tests untreated water to ensure that it is within
standards IAW TB MED 577
Survey three sites
Only sure way to get accurate data for the selection
of water point
