26
This is in gas form as well and the major source comes from the stationary fuel combustion, transportation, industrial processes, and solid waste.
Nitrogen Oxides (NOx)
27
It is in gas form and the major sources comes from the stationary fuel combustion, industrial processes, transportation, and other waste
Sulfur Dioxide (SO2)
28
• This is in metal or aerosol form. Maior sources come from the transportation, industrial processes, stationary fuel combustion, and solid waste.
Lead (Pb)
29
NAAQS or the
National Ambient Air Quality Standard
30
EPA or the
Environmental Protection Agency
31
These are the compounds that exist as vapors over the not normal range of air pressures and temperatures
Volatile Organic Compounds (VOCs)
32
a pungent water soluble gas as one of the most ubiquitous VOCs
Formaldehyde
33
Water in streams, rivers, lakes and reservoirs is called
surface water
34
The water that infiltrates the soil is referred to as
Subsurface water or groundwater
35
Groundwater that is not absorbed by the roots of vegetation moves slowly downwards until it reaches the zone of the soil completely saturated with water referred to as
aquifer
36
are porous water-saturated layers of underground bedrock sand and gravel that can yield economically significant amounts of water.
aquifers
37
The earth's supplies of fresh water available for our use is limited, only________ of the earth's water is available for the use by humans and much of this is hard to reach and too costly to be of practical value.
0.003%
38
Consumption of polluted water can result in outbreaks such as waterborne diseases such as
cholera, typhoid fever, dysentery, and other gastrointestinal diseases
39
Waterborne diseases are responsible for ______ deaths every year
11.5 million
40
In 2010 more than______ of the world's population lived without sanitation.
one-third
41
of the population had no access to clean drinking water.
11%
42
Common pollutants of area rivers, streams, bayous, lakes, ponds, estuaries, and bays include:
Fertilizer Mercury Herbicides/ Insecticides Oil and other chemicals
43
Water pollution includes any physical or chemical change in water that can harm living organisms or unfit for uses such as:
Drinking Domestic use Recreational fishing Industry Agriculture Transportation
44
Source of water pollution • Refers to a single identifiable source that discharges pollutants into the water such as the pipe, ditch or culvert.
Point sources
45
Source of water pollution • Includes all pollution that occurs through the runoff seepage or falling of pollutants into the water.
Non-point sources
46
Release of pollutants in the factory Sewage treatment plant
Point sources
47
• Run-off water from cities, highways, and farms resulting from rain events or called stormwater runoff • Seepage of leachates from landfills and acid rain
Non-point sources
48
is a greater problem than the point source pollution: because of the often difficult track and the actual source of the pollution and therefore to control it.
Non-point source pollution
49
