Environmental Engineering
Environmental Engineering Science (EES)
is a multidisciplinary field of engineering science that
combines the biological, chemical and physical sciences
with the field of engineering. This major traditionally
requires the student to take many basic engineering
classes
in
fields
such
as
thermodynamics,
advanced math, computer modeling and simulation as
well as technical classes in subjects such as
statics, mechanics, hydrology, and fluid dynamics.

Environmental Engineers
Environmental engineers are the technical
professionals who identify and design solutions
for
environmental problems. Environmental
engineers provide safe drinking water, treat
and properly dispose of wastes, maintain air
quality,
control
water
pollution,
and
remediate sites contaminated due to spills or
improper disposal of hazardous substances.
They monitor the quality of the air, water,
and land. And, they develop new and
improved means to protect the environment.

ENVIRONMENTAL ENGINEER
An environmental engineer works
very closely with industry and
companies to ensure that they are in
compliance with all environmental
regulations and laws. In addition to
just working to ensure compliance an
environmental engineer also works
with the company to develop less
costly methods of production that will
still
be
effective
and
within
regulations. This function is very
important for companies as decreasing
the cost of production is important in
overall revenue for the company.

What topics does Environmental Engineering cover?
• Drinking water treatment - ensure an
adequate quantity of safe, high quality
water.
• Wastewater treatment - prevent negative
environmental impacts of the discharged
water and handle residuals generated,
such as bio-solids that can be used as
fertilizer.
• Air quality - design processes to prevent
industrial emissions.

What topics (cont.) ?
• Surface water quality - prevent degradation of
the quality of water in rivers and lakes.
• Solid waste - landfill design, recycling,
destruction processes.
• Hazardous waste - treatment of currently
generated hazardous industrial wastes and
clean-up of past contaminated sites.
• Industrial waste - Minimization/Treatment.
• Health and Safety

Impact of Development on Environment
The basic links in nature’s closed system are:
• The energy source—sunlight
• The earth’s non-living resources—oxygen,
water, etc.
• The plants, from planktons to fully grown
trees.
• The consumers that feed on plant products.
• The decomposers—bacteria, fungi and insects

Impact of Development on Environment
• Development and environment are interrelated
to each other.
Improper or uncontrolled
development is likely to cause adverse impacts
on the environment, and environmental
pollution or degradation may become a major
obstacle for social and economic development.
• Q: Write about the interrelation between the
development and the environment.
