If you’re fascinated by the intricate science of chemistry, you may want to consider a career as a Chemical Technician. Chemical Technicians work in laboratories and manufacturing facilities. They work with-scientists to study various substances, with applications ranging from a new product development…to a major medical breakthrough. Some collect and analyze air and water samples to monitor pollution levels view more

Civil engineers build things. Things like roads, bridges, tunnels, dams, and airports. They combine a knowledge of materials science, engineering, economics, physics, geology, and hydraulics to create the physical infrastructure essential to modern life. Naturally, there are numerous sub-specialties. Surveying and mapping engineers identify the best sites for construction. Hydraulic and irrigation engineers focus on dams, flood control, wells, and reservoirs view more

Buried underground are many minerals and other valuable deposits. Getting to them often requires the expertise of Earth Drillers. Mining companies use Earth Drillers for exploration. They dig up core samples that are then analyzed by geologists and other experts. Drillers are also employed to tap sub-surface water and salt deposits…to do soil testing… or to dig for construction projects. The work can be very demanding physically view more

Pollution is a major problem in today’s world. But we can breathe a little easier if Environmental Engineering Technicians are on the job. Working with environmental engineers and scientists, these technicians test the air, water and soil for pollution. This involves setting up and monitoring sophisticated equipment. If findings indicate that pollution levels need to be further investigated, these technicians become environmental detectives view more

Just about everything we do has an impact on the environment. Measuring that impact is the job of environmental engineers. They apply their engineering skills to assess the effect of projected or actual human activity from the use of off-road recreational vehicles…to housing developments. They also work to manage natural resources, and control pollution. They are also involved in recycling, waste disposal and public health issues view more

There is a price any society pays for progress. Often, that price is measured in damage to our environment or the public health. Environmental Scientists and Specialists, including health specialists, try to stop the damage. These specialists investigate what’s causing the pollution or health hazard. They may perform laboratory and field tests to monitor environmental resources and determine the contaminants and sources of pollution view more

Fire fighters have one of the most hazardous of all occupations. But it is also one of the most essential, for nothing is more damaging -— or more deadly -—than fire. Swinging a fire axe or aiming a fire hose that shoots water at 300 pounds per square inch requires strength and stamina. But fire fighting isn’t only about physical fitness. Most calls to fire departments involve medical emergencies view more

Gas is a product of nature. But it takes a lot of technology to extract gas from nature, and to distribute it for use in industry and homes. Gas Plant Operators are responsible for performing these tasks safely and efficiently. For example, they’re in charge of complex equipment that extracts nitrogen and oxygen from the air. Or they might be in a plant that liquefies, compresses, or re-gasifies natural gas view more

The first century of the Industrial Revolution left a legacy of hazardous waste that government and environmental experts are trying to clean up. Hazardous Materials and Waste Technicians are at the forefront of this effort. Some hazardous waste technicians work on-site; others, in a hazardous materials center, called a “hazmat facility.” There, they perform a variety of tasks including transportation, treatment and storage of hazardous wastes view more

H-VAC technicians are specialists in "heating, ventilation, and air conditioning" equipment. But a more accurate job title might be "human comfort specialist!" Most people take their comfort in a building or house for granted — until something goes wrong. Only then do they realize that they depend on HVAC technicians to keep them cool in summer and warm in winter. And rarely do they ever understand that that their comfort depends on complex systems of pipes, coils, ducts, fans, compressors, and machines view more

Water is one of our most precious resources. Hydrologists help protect that resource. Hydro means water. Ologist means one who studies. So Hydrologists are scientists who study the water in our environment. They use sophisticated techniques and equipment to monitor changes in water cycles. They study precipitation, its movements through the earth, and its return to the ocean and the atmosphere view more

The world’s demand for oil and natural gas is unceasing. To find new supplies of these vital resources, we depend on petroleum engineers. They search the world for reservoirs containing oil or natural gas, and work with geologists and other specialists to extract it. This is not a simple matter of plunging a drill into the ground. First, the team develops a map of the underground, and devises a drilling method, designing equipment and processes for that particular target—whether it be under a mountain, under a desert, or under the ocean view more

An oil refinery is a type of factory where crude oil is broken down into various components, and then recombined into new products…such as gasoline and jet fuel. A team of refinery technicians oversees this process. Refinery operators direct and control the continuous processes in petroleum refining. They're alert to any glitches in the system that might require immediate repairs to avoid damage to the quality and quantity of the product view more

The term plumber comes from the Latin word for lead, the material used for joints and pipes for centuries. Modern plumbers no longer use lead, but they still spend much of their time assembling, installing, and repairing pipes for systems that carry everything from water and steam to oil and gas. Plumbers can be found at construction sites and in residential and commercial buildings, where a great deal of the work involves cutting, bending, threading, and joining pipes and fittings view more

The world runs on oil and gas. Some of the people who help access these vital natural resources are the rotary drill operators. They have the unique expertise to reach the vast fields of oil and gas hidden far underground, whether beneath a sun-baked desert…or a stormy sea. Guided by scientists' field maps, the drillers install a derrick at the site to support the drilling equipment and to stabilize the drill rig view more

It's a dirty job, but somebody's got to do it -- and soil scientists do. They study the properties of soil -- all types of soil -- to help agriculture and other industries use it effectively. Soil scientists split their time between farms and agricultural research stations where they survey and collect soil samples…and laboratories where they use specialized equipment to analyze those samples view more

Water, water, everywhere: but it is safe to use? Water & Waste Treatment Plant Operators treat water so it's safe to drink, while Waste Treatment Plant Operators remove pollutants and other harmful materials from wastewater, making it safe to return to the environment. Water and Waste Treatment Plant Operators read gauges and meters and use computers to make sure that the equipment is operating properly view more
