WHAT ENVIRONMENTAL ENGINEERS DO

Environmental engineers use the principles of engineering, soil science, biology, and chemistry to develop solutions to environmental problems. They are involved in efforts to improve recycling, waste disposal, public health, and control of water and air pollution. They also address global issues, such as safe drinking water, climate change, and sustainability.

Environmental engineers typically do the following:

• Prepare, review, and update environmental investigation reports

• Design projects leading to environmental protection, such as water reclamation facilities, air pollution control systems, and operations that convert waste to energy

• Obtain, update, and maintain plans, permits, and standard operating procedures

• Provide technical support for environmental remediation projects and legal actions

• Analyze scientific data and do quality-control checks

• Monitor progress of environmental improvement programs

• Inspect industrial and municipal facilities and programs to ensure compliance with environmental regulations

• Advise corporations and government agencies about procedures for cleaning up contaminated sites

Environmental engineers conduct hazardous-waste management studies in which they evaluate the significance of the hazard and advise on treating and containing it. They also design municipal water supply and industrial wastewater treatment systems and research the environmental impact of proposed construction projects. Environmental engineers in government develop regulations to prevent mishaps.

Some environmental engineers study ways to minimize the effects of acid rain, global warming, automobile emissions, and ozone depletion. They also collaborate with environmental scientists, planners, hazardous waste technicians, engineers, and other specialists, such as experts in law and business, to address environmental problems and sustainability. For more information, see the job profiles on environmental scientists and specialists, hazardous materials removal workers, lawyers, and urban and regional planners.

RIVER

A river is a stream of water that flows through a "channel" (or passage) in the surface of the ground. The passage where the river flows is called the riverbed and the earth on each side is called a riverbank. A river begins on high ground or in hills or mountains and flows down from the high ground to the lower ground, because of gravity. A river begins as a small stream and gets bigger, the farther that it flows.

The water in a river is called "fresh water". It comes from rain or snow and it can usually be drunk safely, unless it has been polluted. The water in a sea cannot be drunk safely because it is "salt water". Both people and animals often live near rivers, because they need water to survive.

The beginning of a river

The start of a river is called its "source" or its "headwaters". The part of the river that is near the source is called a "young" or "youthful river". A young river is often in a V-shaped river bed, and flows quickly downhill over stones, and around big rocks. Young rivers often have lots of small waterfalls and rapids.

The source of a river may be a spring, often on a hill, mountain, or another high place. A spring is water that flows out from under the ground.

The source of a river may be a lake where lots of water from small streams gathers when it rains or snows.

A river may begin in mountains where there is snow. The melting snow runs together to form a small stream that runs down the mountain. As more little streams run in, the main stream gets bigger, until it forms a river.

Some rivers flow from hills where there is no snow, but lots of rain.

Some rivers only flow after there has been rain at the "headwaters".
