Environmental Science and Protection Technicians

37% increase in jobs 2002 - 2012

Significant Points

Work at remote field sites is common.

Federal, State, and local governments employ nearly one-half of all environmental scientists and geoscientists.

A bachelor's degree is adequate for a few entry-level jobs, but a master's degree is usually the minimum educational requirement; a Ph.D. degree is required for most high-level research positions.

Employment of geoscientists is expected to grow as fast as average, while environmental scientists and hydrologists will experience faster than average growth.

Nature of the Work

Environmental scientists and geoscientists use their knowledge of the physical makeup and history of the Earth to protect the environment; locate water, mineral, and energy resources; predict future geologic hazards; and offer advice on construction and land-use projects.

Environmental scientists conduct research to identify and abate or eliminate sources of pollutants that affect people, wildlife, and their environments. These workers analyze and report measurements and observations of air, water, soil, and other sources and make recommendations on how best to clean and preserve the environment. Understanding the issues involved in protecting the environment degradation, conservation, recycling, and replenishment is central to the work of environmental scientists, who often use their skills and knowledge to design and monitor waste disposal sites, preserve water supplies, and reclaim contaminated land and water to comply with Federal environmental regulations.

Many environmental scientists do work and have training that is similar to other physical or life scientists, but is applied to environmental areas. Some environmental scientists work in managerial positions, usually after spending some time performing research or learning about environmental laws and regulations. Many work as consultants to business firms or to government agencies, helping them comply with environmental policy, particularly with regard to ground-water contamination and flood control. Environmental scientists who determine policy may help identify how human behavior can be modified in the future to avoid such problems as ground-water contamination and depletion of the ozone layer.

Geoscientists study the composition, structure, and other physical aspects of the Earth. With the use of sophisticated instruments and by analyzing the composition of the earth and water, geoscientists study the Earth's geologic past and present.

Oceanographers use their knowledge of geology and geophysics, in addition to biology and chemistry, to study the world's oceans and coastal waters. They study the motion and circulation of the ocean waters; the physical and chemical properties of the oceans; and how these properties affect coastal areas, climate, and weather. Oceanographers are further broken down according to their areas of expertise.

Geoscientists can spend a large part of their time in the field, identifying and examining rocks, studying information collected by remote sensing instruments in satellites, conducting geological surveys, constructing field maps, and using instruments to measure the Earth's gravity and magnetic field. For example, they often perform seismic studies, which involve bouncing energy waves off buried rock layers, to search for oil and gas or to understand the structure of subsurface rock layers. Seismic signals generated by an earthquake are used to determine the earthquake's location and intensity. In laboratories, geologists and geophysicists examine the chemical and physical properties of specimens. They study fossil remains of animal and plant life or experiment with the flow of water and oil through rocks.

Working Conditions

Some environmental scientists and geoscientists spend the majority of their time in an office, but many others divide their time between fieldwork and office or laboratory work. Many environmental scientists, such as environmental ecologists, environmental chemists, and hydrologists, often take field trips that involve physical activity. Environmental scientists in the field may work in warm or cold climates, in all kinds of weather. In their research, they may dig or chip with a hammer, scoop with a net, and carry equipment in a backpack. Oceanographers may spend considerable time at sea on academic research ships. Fieldwork often requires working long hours. Geologists frequently travel to remote field sites by helicopter or four-wheel-drive vehicles and cover large areas on foot. An increasing number of exploration geologists and geophysicists work in foreign countries, sometimes in remote areas and under difficult conditions. Travel often is required to meet with prospective clients or investors.

Employment

Environmental scientists and geoscientists held about 101,000 jobs in 2002. Environmental scientists accounted for 65,000 of the total; geoscientists, 28,000; and hydrologists, 8,000. Many more individuals held environmental science and geosciences faculty positions in colleges and universities, but they are classified as college and university faculty. (See the statement on teachers postsecondary elsewhere in the Handbook.)

About 47 percent of environmental scientists were employed in State and local governments, 14 percent in architectural, engineering and related services, 13 percent in management, scientific, and technical consulting services, and 9 percent in the Federal Government. About 1,900 were self-employed.

Training

A bachelor's degree is adequate for a few entry-level positions, but environmental scientists and geoscientists increasingly need a master's degree in a natural science. A master's degree also is the minimum educational requirement for most entry-level research positions in private industry, Federal agencies, and State geological surveys. A doctoral degree is necessary for most high-level research positions.

Job Outlook

Overall employment of environmental scientists and geoscientists is expected to grow about as fast as the average for all occupations through 2012. Driving job growth will be public policy, which will force companies and organizations to comply with environmental laws and regulations, particularly those regarding ground-water contamination, clean air, and flood control.

Projected employment growth varies by occupational specialty. Environmental scientists and hydrologists are expected to grow faster than average. A general heightened awareness regarding the need to monitor the quality of the environment, to interpret the impact of human actions on terrestrial and aquatic ecosystems, and to develop strategies for ecosystem restoration are all increasingly important issues that will drive demand for environmental scientists. Issues related to water conservation, deteriorating coastal environments, and rising sea levels also will stimulate employment growth of these workers. As the population increases and moves to more environmentally sensitive locations, environmental scientists and hydrologists will be needed to assess building sites for potential geologic hazards, to mitigate the effects of natural hazards such as floods, tornadoes, and earthquakes, and to address issues related to pollution control and waste disposal. Hydrologists and environmental scientists also will be needed to conduct research on hazardous-waste sites in order to determine the impact of hazardous pollutants on soil and ground water so that engineers can design remediation systems. Demand is growing for environmental scientists who understand both the science and engineering aspects of waste remediation.

Earnings

Median annual earnings of environmental scientists were $47,600 in 2002. The middle 50 percent earned between $36,820 and $62,400. The lowest 10 percent earned less than $29,920, and the highest 10 percent earned more than $78,200.
