Physicochemical
measure the causes of pollution andthe +uantity of pollutants
based on fi!e parameters: 3"D, Ammonia, 2itrate,
Phosphates (D")4
3iological measure the effects of pollution
the e1amination of suitable resident organisms
Adaptability of species in the ecology

(efinition
What is water pollution5
occurs when a body of water is ad!ersely
affected due to the addition of large amounts
of materials to the water
6 the loss of any of the actual or potential
beneficial uses of water caused by any
change in its composition due to human
acti!ity7

T#"es of water "ollution
8o1ic substance chemical pollutant that is not a
naturally occurring substance in a+uatic ecosystems e4g herbicides,pesticides, ind compound
"rganic substance occurs when an e1cess of organicmatter, such as manure or sewage, enters the water4
8hermal pollution occur when water is used as acoolant near a power or industrial plant and then is returned to thea+uatic en!ironment at a higher temperature than it was originally4
cological pollution chemical pollution,organic pollution or thermal pollution are caused by nature

)ources
8here are types of sources
Point sources 2on&point sources
occur when
harmful
substances are
emitted directl# into a body of
water from
specific location
9actories, power
plant, oil refinery
A nonpoint source deli!ers
pollutants indirectly through
en!ironmental changese1ample : fertilizer from a
field is carried into a stream
by rain, in the form of run&off
which in turn effects a+uatic
life
Automobile, resident,
agriculture, urban,
construction, business,
storm drain
